Hotel Key Card Compatibility Guide: VingCard, Saflok, SALTO, Onity & Kaba

Hotel key card compatibility is one of the most important factors to confirm before ordering replacement or custom RFID hotel key cards.

A card may have the correct size, the right RFID frequency and even a familiar MIFARE chip, but that does not automatically mean it will work with the hotel’s existing lock system.

VingCard, Saflok, SALTO, Onity, Kaba and other hotel access-control brands have developed multiple generations of locks, software platforms, encoders and credential technologies.

As a result, asking whether a card is simply “VingCard compatible” or “Saflok compatible” is often not specific enough.

The correct hotel key card must match the actual system installed at the property.

This guide explains how hotel key card compatibility works, what information buyers should collect before ordering, and how to reduce the risk of purchasing incompatible RFID cards.

What Does Hotel Key Card Compatibility Mean?

Hotel key card compatibility means that a credential can operate correctly within a specific hotel access-control environment.

This usually involves more than the physical RFID card.

A complete hotel access system may include:

• Electronic hotel locks

• RFID key cards

• Front desk encoders

• Access management software

• Property management system integration

• Security configuration

• Credential encryption

• Staff credentials

• Guest credentials

• Common-area access

• Mobile credentials

For a replacement card to work correctly, the relevant parts of this system need to recognize and process the credential.

This is why two cards that look identical may behave completely differently.

One may encode and open the room normally.

The other may not be recognized by the encoder at all.

Why Lock Brand Alone Is Not Enough

The hotel lock brand is the first thing to identify, but it should not be the last.

A hotel may tell a supplier:

“We need VingCard cards.”

Another may say:

“We use Saflok.”

That information is useful, but major hotel lock manufacturers have produced different lock models and software generations over many years.

An existing installation may therefore differ significantly from a newer property using the same brand.

Hotel key card compatibility may depend on:

• Lock model

• Lock generation

• Access management software

• Software version

• Encoder

• RFID chip

• Credential memory

• Security configuration

• Guest or staff application

• Existing system setup

The correct purchasing process is therefore:

Lock Brand → System → Credential Technology → Sample Verification → Bulk Production

Not:

Lock Brand → Buy Cards

That small difference can prevent a surprisingly expensive purchasing mistake.

Hotel Key Card Compatibility Overview

The following table should be treated as a purchasing guide rather than a universal compatibility chart.

Never use this table to select a chip without further verification.

Its purpose is to show what needs to be checked.

VingCard Key Card Compatibility

VingCard is one of the most widely recognized hotel access-control brands.

Its systems can be found across hotels, resorts and hospitality properties worldwide.

Modern VingCard credential environments may support several physical and digital credential options, including:

• RFID hotel key cards

• Paper RFID cards

• Wooden RFID cards

• PETG cards

• Wristbands

• Key fobs

• Mobile credentials

However, the availability of multiple credential types does not mean that every VingCard credential works with every installed VingCard system.

What to Check for a VingCard System

Before purchasing VingCard-compatible hotel key cards, determine:

1. Lock model or series

2. Access management software

3. Software version

4. Existing key card specification

5. Front desk encoder

6. Current card reference or SKU if available

Existing properties may use systems such as different generations of Visionline or newer Vostio environments.

This matters because card and system compatibility can vary.

Why the Existing VingCard Card Matters

If the hotel already has working cards, do not throw them away when changing suppliers.

Keep:

• Several working cards

• Original packaging

• Product labels

• Previous purchase orders

• Card reference numbers

These references can make identification considerably easier.

If an article number or SKU appears on existing packaging, record it.

Common VingCard Purchasing Mistake

One common mistake is searching for:

“VingCard MIFARE key card”

and assuming that any MIFARE card should work.

MIFARE is a family of contactless products rather than one universal card.

The exact technology and system compatibility still need to be verified.

Saflok Key Card Compatibility

Saflok hotel locking systems are part of the dormakaba hospitality access portfolio.

Saflok installations may include different lock generations, software platforms and credential configurations.

Current RFID hotel lock products can support physical RFID credentials as well as mobile access.

What to Check for a Saflok System

Before ordering Saflok key cards, collect:

• Saflok lock model

• Access management software

• Existing RFID card

• Encoder model

• Software version

• Existing card packaging

• Previous supplier information if available

Current and legacy Saflok installations should not automatically be treated as identical.

Saflok Ambiance and Legacy Systems

Modern dormakaba hospitality environments may use Ambiance access management.

Older hotels may still operate legacy Saflok systems.

The credential specification should therefore be confirmed against the actual property configuration.

This is particularly important for hotels replacing cards without replacing the locks.

RFID Technologies Used in Saflok Environments

Different Saflok RFID products and system generations may support different contactless credential technologies.

Therefore, a buyer should not make a purchase based only on statements such as:

“Saflok uses MIFARE.”

That description is too broad.

The exact chip generation and system configuration should be confirmed.

When to Request Saflok Samples

Sample testing is strongly recommended when:

• Changing card suppliers

• Changing card material

• Migrating from PVC to wood

• Using customized RFID cards

• The existing chip specification is uncertain

• The property operates an older Saflok system

• A large order is planned

A working test credential is worth far more than an impressive product description that turns into 20,000 decorative rectangles at the hotel reception desk.

SALTO Key Card Compatibility

SALTO access-control systems are used in hospitality as well as commercial, residential, education and other environments.

SALTO systems can use physical credentials such as:

• RFID cards

• Wristbands

• Key fobs

They can also support digital credentials depending on the installed platform and configuration.

SALTO Data-on-Card

In SALTO Space environments, physical credentials can carry access information used by the system.

This makes credential selection part of the overall SALTO access architecture rather than simply a matter of card frequency.

What to Check Before Ordering SALTO Key Cards

Provide:

• SALTO lock model if known

• SALTO management platform

• Existing working card

• Existing chip specification

• Encoder model

• Property configuration information

Do not assume that a generic 13.56 MHz card will operate correctly just because the SALTO reader is contactless.

Customized SALTO-Compatible Hotel Cards

Hotels often want to replace plain cards with custom hotel-branded credentials.

This can be possible when the correct technical credential is used.

Customization options may include:

• Hotel logo

• Brand colors

• Guest instructions

• QR codes

• Promotional information

• Serial numbers

• Custom finishes

Technical compatibility should be confirmed before artwork production.

Onity Key Card Compatibility

Onity has supplied electronic hotel locking systems to the hospitality market for many years.

Its product portfolio includes RFID hotel locking systems, access management software and mobile access technology.

Current Trillium RFID systems can support different RFID credential technologies depending on configuration.

Onity Trillium RFID

Onity Trillium is a contactless hotel locking platform that can support key cards and other RFID credential formats.

Depending on the configuration, supported credential technologies can include different MIFARE products.

This means the phrase:

“Onity RFID card”

still does not provide enough information for reliable bulk production.

OnPortal and Encoding

Onity’s OnPortal platform supports hotel access management and RFID card encoding.

The encoder and software environment are therefore useful pieces of information when identifying the correct replacement hotel card.

What to Provide for an Onity Project

Collect:

• Lock model

• Onity system generation

• Current key card

• Current chip if known

• OnPortal or other software information

• Encoder model

• Existing card packaging

• Previous order references

When available, send an existing working card for verification.

Kaba Hotel Key Card Compatibility

Many hotels still refer to their installed access system simply as Kaba.

This terminology remains common in purchasing inquiries, especially for systems installed before or around the transition to the dormakaba brand.

Today, Kaba is part of dormakaba following the combination of DORMA and Kaba.

However, this does not mean a buyer should simply order a generic “dormakaba card” for every older Kaba installation.

Legacy properties may have:

• Older lock hardware

• Different software

• Different encoders

• Different credential technology

• Existing system-specific requirements

What to Do With a Legacy Kaba System

Start with the existing property rather than the current brand name.

Identify:

• Lock model

• Existing working card

• Hotel access software

• Encoder

• Installation age if known

• Previous card specification

For older hotel installations, this information is often much more useful than simply knowing the corporate brand.

RFID Frequency and Hotel Key Card Compatibility

Many RFID hotel key cards operate at 13.56 MHz.

However, 13.56 MHz is a frequency, not a complete credential specification.

Multiple contactless technologies can operate within the same frequency range.

Therefore:

Same frequency does not mean same compatibility.

A hotel procurement team should confirm:

• Frequency

• Chip family

• Exact chip generation

• Memory requirements where relevant

• Security configuration

• System compatibility

This is one of the most important rules in hotel RFID card purchasing.

MIFARE Does Not Mean One Card Type

Another common source of confusion is the word MIFARE.

Buyers may receive an inquiry such as:

“We need 10,000 MIFARE hotel cards.”

That still leaves important questions unanswered.

The MIFARE portfolio includes different product families and generations.

Examples include:

• MIFARE Classic

• MIFARE Ultralight

• MIFARE Plus

• MIFARE DESFire

Different products offer different memory, security and application capabilities.

A hotel lock system designed around one credential configuration should not automatically be expected to work with another.

The safest rule is:

Match the existing approved credential unless the hotel access system provider confirms a migration or upgrade path.

Physical Card Compatibility vs System Compatibility

Hotel buyers should understand the difference between two concepts.

Physical RFID Compatibility

This refers to the underlying hardware characteristics of the credential, including:

• Frequency

• Chip

• Antenna

• Form factor

System Credential Compatibility

This refers to whether the credential can actually be issued and used within the hotel access system.

It may involve:

• Encryption

• System keys

• Credential preparation

• Data structure

• Software configuration

• Encoder support

A card can have apparently suitable hardware while still not functioning as a usable hotel credential.

This distinction becomes increasingly important with more secure access-control systems.

Can Third-Party Hotel Key Cards Work?

In some installations, compatible third-party or custom-manufactured credentials may be possible.

In others, credential preparation, security requirements or manufacturer policies may limit the available sourcing options.

This should be confirmed for the specific system.

Hotels should never assume that:

• Every blank card can be encoded

• Every matching chip is interchangeable

• Every card advertised online as compatible has been verified

• Changing suppliers requires no testing

For large purchases, request samples and test them in the actual hotel environment.

How to Identify an Unknown Hotel Key Card

Sometimes the purchasing department does not know what card the hotel uses.

This is especially common when:

• The system was installed years ago

• Staff have changed

• Original documentation has been lost

• Cards were purchased through an installer

• The previous supplier is no longer available

In this situation, collect as much evidence as possible.

Start with the existing working card.

Then gather:

• Front and back photos

• Card markings

• Packaging labels

• Lock photos

• Lock model numbers

• Encoder information

• Software name

• Software version

• Previous invoices

An experienced supplier may be able to narrow down the credential type from this information.

For uncertain projects, physical sample inspection may still be required.

Can a Phone App Identify the Hotel Key Card?

Some smartphones can detect certain NFC-compatible contactless cards and display limited technical information.

However, this should not be treated as a complete hotel key card compatibility test.

A smartphone may identify certain basic characteristics but cannot necessarily determine:

• Hotel-specific credential configuration

• Protected data

• System encryption

• Encoder compatibility

• Complete access application structure

Phone detection can provide a clue.

It should not replace system verification.

Can You Change the Hotel Key Card Material?

Once the technical credential has been confirmed, hotels may consider changing the physical material.

Possible options include:

• PVC

• Recycled PVC

• PETG

• Wood

• Bamboo

• Paper-based materials

• Specialty composite materials

For example, a hotel moving toward a more environmentally focused brand image may want to replace conventional PVC cards with wooden or paper hotel key cards.

The RFID inlay and credential technology still need to meet the lock-system requirements.

Compatibility of Wooden RFID Hotel Key Cards

Wooden hotel key cards are increasingly used by:

• Resorts

• Eco hotels

• Luxury hotels

• Boutique hotels

• Glamping properties

• Nature-focused hospitality brands

However, buyers should test more than RFID functionality.

Check:

• Card thickness

• Encoder handling

• RFID reading

• Door opening

• Surface durability

• Moisture resistance

• Printing or engraving

• Reusability

Alternative material should improve the guest experience without creating problems at reception.

Hotel Key Card Size and Compatibility

CR80 is one of the most widely used hotel card formats.

Its nominal dimensions are approximately:

85.60 × 53.98 mm

However, alternative card materials may have different thicknesses.

This can matter when the card interacts with:

• Desktop card encoders

• Card printers

• Kiosks

• Automatic card dispensers

• Card holders

A hotel using self-service kiosks should pay particular attention to dimensional tolerances.

Hotel Key Card Compatibility Testing Process

Before mass production, use a structured test.

Step 1: Confirm Card Identification

Verify the proposed chip and credential specification.

Step 2: Encode the Card

Use the hotel’s normal front desk encoder and access-management software.

Step 3: Test Guest Room Access

Test several guest-room locks rather than only one.

Step 4: Test Common Areas

Where applicable, test:

• Elevators

• Parking

• Gym

• Pool

• Spa

• Executive lounge

• Main entrance

Step 5: Test Validity

Verify normal check-in and expiration behavior according to the hotel system.

Step 6: Test Reuse

If cards will be collected and reused, perform repeated issuance tests.

Step 7: Test the Physical Card

Evaluate printing, bending, moisture exposure and normal guest handling.

Only after successful testing should large-volume manufacturing begin.

Compatibility Checklist Before Ordering

Before placing a bulk hotel key card order, confirm the following:

If several technical items remain unknown, do not rush into mass production.

Resolve the uncertainty first.

Information to Send Your Hotel Key Card Supplier

A useful hotel key card RFQ should contain more than quantity and artwork.

For example:

Hotel Lock Brand: VingCard
Lock Model: Known / Unknown
Software: Visionline / Vostio / Other / Unknown
Existing Card: Photos attached
Chip: If known
Encoder: Model or photo attached
Material: PVC / Wood / Paper / Other
Size: CR80 or custom
Printing: Double-sided
Finish: Matte
Quantity: 20,000 pieces
Annual Demand: 100,000 pieces
Sample Testing: Required

This gives the supplier a much better basis for technical evaluation.

Common Hotel Key Card Compatibility Mistakes

Assuming Every Card From the Same Brand Is Identical

Hotel access systems evolve.

Older and newer installations may use different technologies.

Choosing by Frequency Alone

13.56 MHz is not enough information.

Choosing by the Word MIFARE

MIFARE is a family of technologies.

Ordering by Appearance

A white card looks very much like another white card.

Electronics, regrettably, are not moved by aesthetics.

Changing Chips Without Verification

A newer or more secure chip is not automatically backward compatible.

Skipping Testing

Sample testing is one of the cheapest forms of risk control in a hotel card project.

Buying a Large Quantity Before Confirming the System

The unit price may look better.

The cost of 50,000 incompatible cards will look considerably worse.

Choosing the Right Hotel Key Card Supplier

A professional supplier should ask technical questions before accepting a large order.

For existing hotel lock installations, useful questions include:

• Which lock brand?

• Which model?

• Which software?

• Which chip?

• Do you have an existing card?

• Can you provide an encoder photo?

• Have samples been tested?

A supplier that immediately confirms compatibility from nothing more than a brand name is skipping information that may matter.

Hotel key card manufacturing requires both printing experience and RFID knowledge.

Frequently Asked Questions

Are all VingCard hotel key cards the same?

No. VingCard has different lock systems, software environments and credential options. The installed system should be confirmed before ordering replacement cards.

Which RFID card works with Saflok?

The answer depends on the Saflok lock model, software environment and credential configuration. The existing card and system should be verified before choosing a replacement.

Can any MIFARE card work with SALTO?

No. MIFARE is a family of contactless technologies. The specific credential supported by the installed SALTO system needs to be confirmed.

What RFID cards work with Onity?

Different Onity lock generations and configurations may support different RFID credentials. The exact lock, software and existing card should be checked.

Is Kaba the same as dormakaba?

Kaba became part of dormakaba following the combination of DORMA and Kaba. Many hotels still use the Kaba name when referring to legacy installed systems.

Can I use a 13.56 MHz card with any hotel RFID lock?

No. Matching the frequency alone does not guarantee compatibility.

How can I find out which chip my hotel key card uses?

Check original specifications, packaging, previous invoices or system documentation. A working sample can also help with identification.

Can GSRFID copy my existing hotel key card?

The correct approach is to identify and supply a credential that is legitimately compatible with the customer’s authorized hotel access system. Protected access credentials or proprietary security data should not simply be duplicated.

Should I send a sample before ordering?

Yes, particularly if the exact specification is uncertain or you are changing suppliers or card materials.

Can wooden cards replace plastic hotel key cards?

In many projects, alternative card materials are possible when the correct RFID credential can be integrated. Sample testing should confirm both system performance and physical handling.
