Can you manufacture RFID hotel key cards compatible with our existing hotel lock system? Yes. We can manufacture RFID hotel key cards designed to work with a wide range of hotel lock and access control systems. To ensure compatibility, we normally need to confirm the hotel lock brand and model, RFID chip type, card specifications, encoding requirements, and system configuration. An original hotel key card sample is also highly recommended for evaluation and testing before mass production. 2. Can you make encrypted hotel key cards? Yes. We can provide RFID hotel key cards for systems requiring encryption, authentication, or specific data encoding. The exact solution depends on the hotel lock system and its security architecture. For protected systems, the required encryption keys, credentials, or encoding procedures normally need to be provided by the authorized system provider, hotel operator, or system integrator. We can manufacture the cards according to the confirmed technical requirements and support sample testing for system compatibility. 3. Which hotel lock systems do your RFID cards support? We can provide RFID hotel key card solutions for various hotel lock systems, including VingCard, Saflok, MIWA, SALTO, Onity, dormakaba/Kaba, Häfele, ADEL, Kale, and other RFID-based hotel access systems. Supported chip technologies may include MIFARE Classic 1K/F08, MIFARE Ultralight EV1, MIFARE Ultralight C, and other RFID technologies required by specific systems. Since the same brand may have different lock models and card technologies, we recommend confirming the exact lock model and testing a sample before bulk production. 4. Can you copy or reproduce an existing hotel RFID key card? Yes. We can reproduce the physical card specifications, RFID technology, antenna structure, printing, and other requirements based on an existing card sample for authorized applications. However, if the original card contains protected encryption keys or proprietary system data, it cannot simply be duplicated without the necessary authorization or technical information. For system-compatible projects, we recommend providing an original card sample together with the hotel lock/system information so that we can evaluate the required card specifications. 5. How can I make sure an RFID hotel key card is compatible with my hotel lock system? The best way is to provide us with the following information: Hotel lock brand and model Original RFID key card sample, if available Chip type or part number, if known Card size and thickness Encoding or encryption requirements Required quantity Our technical team can evaluate the chip, antenna, card construction, and RF characteristics, and recommend the appropriate card solution. For new projects or replacement cards, we strongly recommend sample testing with the actual hotel lock system before mass production to verify compatibility and reliable performance. 1. What are RFID hotel key cards? RFID hotel key cards are contactless cards used with hotel door locks and access control systems. They typically use 13.56 MHz RFID technology and can be customized with the hotel's logo, artwork, colors, and required chip technology. 2. Can you manufacture RFID hotel key cards compatible with our existing hotel lock system? Yes. We can manufacture system-compatible RFID hotel key cards based on your existing lock system and card specifications. For compatibility, we normally need to confirm the hotel lock brand/model, chip type, card technology, encoding/encryption requirements, and original sample card when available. 3. Which hotel lock systems do you support? We can provide RFID cards for various hotel lock systems, including solutions for brands such as V Card Ving System, Saflok, MIWA, SALTO, Onity, Kaba/Dormakaba, Häfele, ADEL, Kale and other systems. Compatibility depends on the specific lock model and system configuration, so we recommend testing samples before mass production. 4. Can you make encrypted hotel key cards? Yes. We can manufacture hotel cards that require specific encryption, authentication, or system encoding, provided that the required technical specifications or encoding procedure are available. For security reasons, the encryption keys and system credentials should normally be provided or managed by the hotel, system integrator, or authorized system provider. 5. What is the difference between a standard RFID card and a system-compatible hotel key card? A standard RFID card mainly refers to the physical card and RFID chip. A system-compatible hotel key card must also meet the requirements of the specific hotel lock system, such as: Chip type Memory structure UID requirements Data format Authentication Encryption Sector/application configuration Encoding procedure RF performance Therefore, simply using the same chip type does not always guarantee system compatibility. 6. Can you copy our existing hotel key card? We can help reproduce the physical card specifications and RFID technology based on an original sample for authorized applications. However, if the card contains proprietary encryption keys or protected system data, we cannot simply duplicate protected credentials without the necessary authorization or technical information from the system owner/provider. 7. What information do you need to quote a compatible hotel key card? Ideally, please provide: Hotel lock brand Lock model Chip type Card size and thickness Card material Required quantity Printing/design requirements Encoding/encryption requirements Original card sample, if available With this information, we can recommend the appropriate card solution and provide a quotation. 8. Can you provide samples for compatibility testing? Yes. We recommend sample testing before mass production, especially for system-compatible or encrypted hotel cards. We can provide samples with the required chip and antenna configuration for your testing. 9. Can you supply both printed and encoded hotel key cards? Yes. We can provide one-stop production, including RFID chip integration, antenna, printing, lamination, die-cutting, encoding, QC, and packaging. Depending on the project, cards can be supplied as blank, printed, pre-encoded, or system-compatible cards. 10. What RFID chips are commonly used for hotel key cards? Depending on the hotel lock system, common technologies include: MIFARE Classic 1K / F08 MIFARE Ultralight EV1 MIFARE Ultralight C Other MIFARE or NFC/RFID technologies required by specific systems The correct chip should be selected according to the actual lock system rather than simply choosing the most common chip. 11. Can you manufacture custom hotel key cards with our logo? Yes. We offer OEM/ODM customization, including: Custom artwork Hotel logo Pantone/custom colors Magnetic stripe Signature panel Numbering QR code RFID/NFC chip Custom card shape Special materials 12. Can you manufacture wooden or eco-friendly RFID hotel key cards? Yes. We can manufacture wooden RFID hotel key cards and other eco-oriented card solutions, depending on the requirements of the hotel lock system. The RFID antenna and chip must be properly integrated into the card to maintain stable RF performance. 13. What is the typical reading distance of an RFID hotel key card? The actual reading distance depends on the chip, antenna design, card construction, reader/lock antenna, and operating environment. For hotel door locks, the practical requirement is usually reliable short-range reading rather than maximum read distance. We therefore optimize the card antenna for compatibility and stable performance with the customer's lock system. 14. How do you ensure the quality of RFID hotel key cards? Each card can go through multiple quality-control stages, including: RFID chip testing Antenna/RF performance testing Printing inspection Lamination inspection Encoding verification Visual inspection Sampling inspection before shipment For system-compatible projects, we also recommend testing samples with the customer's actual hotel lock system before bulk production. 15.
