SALTO key cards are widely used in hotels, resorts, serviced apartments and other hospitality access-control environments.
But selecting a replacement or customized SALTO RFID key card requires more than matching the card size, RFID frequency or chip name.
SALTO access systems can use different physical and digital credential technologies, and the credential itself may play an active role in carrying access information within the SALTO Virtual Network.
This means a card that contains a technically similar RFID chip is not automatically ready to work as a SALTO hotel key card.
Before ordering replacement or custom SALTO key cards, hotel operators, distributors and access-control integrators should identify the installed SALTO platform, credential technology, card configuration and encoding environment.
This guide explains how SALTO key card compatibility works, which RFID technologies may be used, how SALTO Space manages hotel credentials, and what buyers should verify before bulk production.

ToggleWhat Is a SALTO Key Card?
A SALTO key card is a contactless physical credential used with compatible SALTO electronic access-control systems.
Depending on the installation, a physical SALTO credential may take the form of:
RFID key card
Wristband
Key fob
Other contactless credential
SALTO systems can also support digital credentials, including mobile and wallet-based access in compatible environments.
For hotels, guest credentials can provide access to:
Guest rooms
Suites
Hotel entrances
Elevators
Fitness centers
Swimming pools
Business centers
Parking
Executive lounges
Other authorized areas
The hotel access management system determines who can access which locations and during what time period.
Are All SALTO Key Cards the Same?
No.
This is the most important point for anyone purchasing SALTO hotel key cards.
The phrase:
“SALTO-compatible card”
does not describe a complete credential specification.
Different SALTO installations can use different:
Access management platforms
RFID chip technologies
Memory configurations
Security configurations
Credential formats
Encoding requirements
System keys
Application structures
Even two cards containing chips from the same MIFARE family may not necessarily be interchangeable.
Before purchasing, identify the actual system installed at the hotel.
SALTO Space and Hotel Access Control
SALTO Space is an on-premise access management platform used across different access-control environments, including hospitality.
Space includes specific hotel functionality for managing:
Guest check-in
Guest check-out
Hotel rooms
Suites
Guest access levels
Staff users
Guest key issuance
Lost keys
Spare keys
Optional hotel facilities
During hotel check-in, the operator can assign the guest to a room and encode the relevant access information onto the credential.
SALTO Space distinguishes between users, visitors and hotel guests, allowing properties to manage different access requirements for each type of cardholder.
What Is SALTO Data-on-Card?
SALTO’s data-on-card architecture is one of the most important concepts to understand when selecting SALTO credentials.
In SALTO Space, physical credentials can carry access information.
Instead of relying entirely on every individual offline lock being constantly connected to a central server, the credential can help transfer relevant access-control information throughout the installation.
This architecture forms part of the SALTO Virtual Network, commonly referred to as SVN.
A physical credential can therefore play a more active role than simply presenting a fixed serial number to a reader.
This is one reason why selecting a SALTO-compatible card involves more than finding an RFID chip operating at the correct frequency.
What Is the SALTO Virtual Network?
The SALTO Virtual Network is designed to combine online access-control infrastructure with battery-powered electronic locks.
Access information can be stored and updated on contactless credentials.
When users interact with suitable online readers, credential information can be updated.
The credential then carries relevant information as the user moves through the installation.
This allows offline locks to participate in a broader access-control environment without requiring every door to have a permanent wired network connection.
For hotels, this architecture can provide flexibility across:
Guest rooms
Common areas
Staff areas
Elevators
Other hotel access points
The credential therefore needs to be correctly configured within the SALTO environment.
Which RFID Technologies Does SALTO Use?
SALTO supports different contactless credential technologies depending on the product, platform and system configuration.
Current SALTO standard key card products include technologies such as:
MIFARE DESFire EV3
MIFARE Plus EV2
SALTO Space can also be configured for additional credential types, including several MIFARE technologies.
Therefore, buyers should never assume that every SALTO installation uses exactly the same chip.
MIFARE DESFire SALTO Key Cards
MIFARE DESFire is commonly associated with secure contactless access-control applications.
Current SALTO key card products include MIFARE DESFire EV3 credential options.
DESFire provides capabilities appropriate for applications requiring advanced security and multiple applications on one credential.
However, the phrase:
“MIFARE DESFire card”
still does not completely define a SALTO credential.
SALTO Space DESFire configuration can involve parameters such as:
Memory allocation
Application identifiers
Encryption
Keys
Security settings
Issuing configuration
Therefore, buying a generic DESFire card with the same memory size does not automatically mean the card is ready for use in a particular SALTO system.
MIFARE DESFire EV3 and SALTO
DESFire EV3 is part of SALTO’s current credential portfolio.
It operates within the 13.56 MHz contactless smart-card environment and can provide advanced security functionality.
Hotels considering DESFire EV3 credentials should verify:
SALTO platform
System configuration
Memory requirement
Issuing configuration
Encoder compatibility
Existing credential
Credential preparation requirements
If replacing existing cards, the safest approach is to start from the hotel’s approved credential specification.
MIFARE Plus SALTO Key Cards
MIFARE Plus is another technology supported within SALTO environments.
Current SALTO standard cards include MIFARE Plus EV2 options.
SALTO Space also provides configuration support for MIFARE Plus credentials.
Depending on the installation, memory and credential configuration may vary.
Hotels should therefore confirm the exact Plus credential required instead of simply requesting:
“MIFARE Plus SALTO cards.”
MIFARE Classic and Existing SALTO Systems
SALTO Space documentation also includes configuration support for MIFARE Classic credentials, including Classic 1K and Classic 4K.
This is important for existing installations.
A hotel operating a SALTO system installed years ago should not assume its current card technology is identical to SALTO’s newest standard card portfolio.
Older systems may continue to use established credential technologies.
For replacement projects, always inspect:
Existing working cards
Previous card specifications
SALTO Space configuration
Encoder configuration
Original installation records
Do not change credential technologies casually.
Does SALTO Use 13.56 MHz RFID?
Many SALTO smart credentials use 13.56 MHz contactless technology.
Current SALTO standard key cards operate at 13.56 MHz and use an ISO/IEC 14443 Type A contactless interface.
However:
13.56 MHz does not equal SALTO compatibility.
Many completely different RFID and NFC products operate at the same frequency.
A card needs to match the required:
Chip technology
Memory
Security
Credential configuration
SALTO application
Encoding environment
Frequency is only the first layer.
Why a Generic RFID Card May Not Work With SALTO
Imagine two cards:
Card A:
13.56 MHz
DESFire EV3
4K memory
Card B:
13.56 MHz
DESFire EV3
4K memory
On a simple product comparison table, they may appear identical.
But access-control credentials can also involve:
Application configuration
Encryption keys
Memory allocation
Credential initialization
System-specific data
One may be correctly prepared for the hotel installation.
The other may simply be a blank RFID card.
Hardware similarity does not automatically equal system compatibility.
Tiny chips remain stubbornly indifferent to the purchasing department’s spreadsheet.
SALTO Space Credential Issuing
SALTO Space can issue and manage physical credentials using supported encoders.
When a key is assigned, access information relevant to that user or guest can be written to the credential.
Depending on the system, this may include information defining:
Where access is allowed
When access is valid
Credential status
Other access-control information
For hotel environments, guest cards can be encoded during the normal check-in process.
This is why replacement cards should be tested using the hotel’s actual SALTO encoder and software rather than only with a generic RFID reader.
SALTO NCoder and Card Encoding
Current SALTO Space documentation references the NCoder for configuring and issuing several credential technologies.
Existing properties may also use legacy encoders.
When evaluating replacement key cards, buyers should identify:
Encoder model
Connection method
Supported credential technologies
SALTO Space version
Existing encoding workflow
A replacement card must function throughout the full operational process, not merely respond to an NFC reader.
SALTO Hotel Guest Key Cards
SALTO Space includes specific guest management functionality for hotels.
Hotel staff can issue credentials based on:
Guest room
Suite
Check-in date
Check-out date
Additional rooms
Optional facilities
Guest access levels
SALTO also supports multiple guest credentials for the same reservation when configured appropriately.
This allows families, couples and group travelers to receive individual credentials.
Guest Cards vs Staff Cards
Hotels should distinguish between guest and staff credentials.
Guest Key Cards
Guest cards generally require:
Temporary validity
Room access
Selected common-area access
Expiration according to stay dates
Staff Key Cards
Staff credentials may require:
Longer validity
Multiple guest floors
Housekeeping areas
Maintenance rooms
Offices
Back-of-house access
Department-specific areas
Because their access requirements differ, hotels should not automatically assume that guest and staff credentials should have identical configurations.
Lost SALTO Hotel Key Cards
Hotel access systems must account for lost guest cards.
SALTO Space includes functionality for managing lost guest credentials and restricting further use according to the system configuration.
This is one of the advantages of electronic hotel access compared with traditional mechanical keys.
A physical card can be replaced without changing the mechanical lock cylinder for every lost guest key.
Operational procedures should still be established so hotel staff respond quickly when a guest reports a missing credential.
SALTO Key Card Size
SALTO’s current standard smart key cards use the familiar CR80 card format.
Typical current specifications are approximately:
85.6 × 54 mm
with a thickness of approximately:
0.84 mm
This is similar to conventional credit-card dimensions and makes the format convenient for:
Wallets
Card holders
Hotel front desk operations
Card encoders
Customized printing
Alternative materials may have different physical characteristics, so dimensional compatibility should still be verified.
SALTO Key Card Materials
SALTO credentials do not have to be conventional PVC cards.
Current SALTO credential offerings include options such as:
Plastic RFID cards
Bamboo hotel guest cards
Paper-based cards
This gives hotels more flexibility to align guest credentials with sustainability and branding objectives.
PVC SALTO Hotel Key Cards
PVC remains widely used because it provides:
Stable manufacturing
High-quality printing
Good durability
Consistent dimensions
Smooth surfaces
Cost-effective bulk production
Hotels requiring frequent reuse may still find traditional plastic cards practical.
Bamboo SALTO Hotel Key Cards
Bamboo RFID cards can provide a more natural appearance for hotels looking to reduce reliance on conventional plastic credentials.
They are particularly suitable for:
Resorts
Eco hotels
Luxury lodges
Boutique hotels
Glamping properties
Nature-focused destinations
SALTO currently offers bamboo hotel guest key card options within its credential range.
When sourcing alternative bamboo credentials, however, hotels should still verify system compatibility and physical performance.
Wooden SALTO Key Cards
Customized wooden RFID hotel key cards may also be considered when a suitable RFID credential can be integrated into the card construction.
Testing should include:
Card encoding
Door reading
Read stability
Card thickness
Surface durability
Moisture resistance
Printing or engraving
Repeated use
The goal is to improve the guest experience without causing the front desk to develop a personal vendetta against the cards.
Paper SALTO Hotel Key Cards
Paper-based RFID hotel key cards are another option for properties seeking alternatives to conventional plastic.
Current SALTO credential offerings include paper-based key card options.
Hotels considering paper credentials should evaluate:
Length of stay
Card reuse policy
Humidity
Moisture
Surface coating
Print durability
Guest handling
The correct material depends on the actual property environment.
Can You Replace PVC SALTO Cards With Wood or Paper?
Potentially, provided the correct credential technology can be integrated into the alternative material and the finished product functions correctly with the installed SALTO environment.
Before bulk production, test:
Encoding
Guest check-in
Room-door reading
Common-area access
Credential expiration
Card reuse where applicable
Encoder handling
Physical durability
Changing material should not mean changing technical compatibility accidentally.
Custom SALTO Hotel Key Cards
Hotels can use their key cards as part of the overall guest branding experience.
A customized SALTO-compatible hotel card may include:
Hotel logo
Brand colors
Property name
Wi-Fi information
Guest instructions
QR codes
Restaurant information
Spa booking
Check-out instructions
Loyalty program
Social media
Website address
Emergency information
For hotel chains, designs can also be adapted for individual properties while retaining group branding.
QR Codes on SALTO Hotel Key Cards
Printed QR codes can coexist with RFID functionality.
A QR code can direct hotel guests to:
Digital guest directory
Wi-Fi login
Restaurant menu
Room service
Spa booking
Hotel app
Concierge services
Local travel information
Loyalty program
Express check-out
The QR code is optically scanned by a phone camera.
The RFID credential performs the access-control function.
The two technologies are independent and can work together on the same card.
Variable Data Printing
Customized hotel cards can also include unique visible information such as:
Serial numbers
QR codes
Barcodes
Membership numbers
Internal inventory references
Variable-data projects require careful production control to prevent duplicate or mismatched records.
Hotels and distributors ordering personalized credentials should define the data format before production.
Printing and Finishing Options
Depending on card material, available customization can include:
Full-color CMYK printing
Pantone color matching
Matte finish
Glossy finish
Spot UV
Gold foil
Silver foil
QR codes
Barcodes
Serial numbering
Laser engraving
Variable printing
For premium hotels, finishing quality can substantially affect the perceived quality of the credential.
Always approve artwork before mass production.
SALTO Mobile Keys
SALTO systems can also support digital credentials.
SALTO Space distinguishes between physical keys and digital keys.
Depending on system configuration and licensing, digital credentials can include mobile access options.
SALTO’s hotel functionality also supports mobile guest credentials in compatible installations.
This gives hotels the option of combining:
Physical RFID cards
Smartphone credentials
Wallet-based credentials
Apple Wallet Hotel Keys
SALTO currently provides support for hotel guest wallet-key deployments in compatible SALTO Space environments.
Official SALTO documentation describes integrations that can enable hotel room keys in Apple Wallet through appropriate hotel wallet credential infrastructure.
Such systems require compatible:
Hardware
Firmware
SALTO Space configuration
Licensing
Hospitality integration
Therefore, digital wallet capability should be evaluated as a complete system project, not simply as a replacement for card purchasing.
Will Mobile Keys Replace SALTO RFID Cards?
Not necessarily.
Many hotels can benefit from supporting both physical and digital credentials.
Physical cards remain useful for:
Guests without smartphones
Guests with unsupported devices
Families
Group bookings
Conference attendees
Children
Backup access
Staff credentials
Emergency operations
Mobile access expands guest choice.
It does not automatically make physical RFID cards obsolete.
How to Identify an Existing SALTO Key Card
If you do not know the card specification, start with the property itself.
Check SALTO Space
Ask the administrator or integrator to identify the enabled credential technologies.
Check Existing Card Packaging
Look for:
Product number
Chip
Memory
Credential reference
Manufacturer information
Check Previous Purchase Orders
Old quotations or invoices may contain the exact card specification.
Keep Working Samples
Retain several known working cards as technical references.
Identify the Encoder
Record:
Encoder type
Model
Connection method
Ask the SALTO Integrator
For projects involving secure credential configuration, the original SALTO installer or authorized technical partner can provide valuable system information.
Can You Identify a SALTO Card With a Smartphone?
A compatible smartphone may detect limited information from some contactless cards.
However, smartphone detection cannot necessarily identify:
SALTO application configuration
Security keys
Protected memory
Credential setup
Complete system compatibility
Phone scanning can provide technical clues.
It should not be treated as proof that a replacement card will work.

Common SALTO Key Card Purchasing Mistakes
Buying by Frequency Only
13.56 MHz does not define a SALTO credential.
Buying by Chip Name Only
A generic DESFire or MIFARE Plus card is not automatically a complete SALTO credential.
Ignoring SALTO Data-on-Card
The physical card may carry access-control data and participate in the SALTO Virtual Network.
Assuming Every SALTO Installation Is the Same
Credential technologies and configurations can vary.
Changing Chip Technology Without System Review
A newer chip is not automatically compatible with an existing installation.
Testing With Only an NFC Reader
A generic RFID reader cannot reproduce the complete hotel access system.
Skipping the Encoder Test
The card must work with the hotel’s actual issuing process.
Ordering Bulk Quantities Before Testing
A low unit price loses some of its charm when every card is unusable.
