MIFARE Ultralight C: A Game Changer for the Future of Hotel Security
In todays world, where customer experience and data security are crucial the hospitality industry is constantly seeking technologies that can enhance both. One emerging trend that has caught the attention of many is the adoption of MIFARE Ultralight C chips for hotel cards after the discontinuation of MIFARE Classic chips.
As the hotel industry evolves these chips are proving to be a choice due to their security features user friendly interface, efficient access control capabilities and sustainability that is compatible with existing MIFARE infrastructures

What sets “MIFARE Ultralight C” apart?
13.56 MHz – MIFARE Ultralight C is an integrated circuit (IC) developed by NXP Semiconductors. It utilizes radio frequency identification (RFID) technology. Boasts a memory capacity of 1536 bits. The chip incorporates Triple DES security mechanisms making it an ideal option for hotel cards as it provides exceptional protection against fraudulent activities. Many hotel lock vendors such as; Onity, Salto, Dormakaba (Saflok) have already implemented Ultralight C in their complete system solutions.
Unmatched Security Measures For Your Hotel
The transition, to MIFARE Ultralight C primarily revolves around its security features. By employing the Triple Data Encryption Standard (3DES) an encryption protocol widely used in finance this chip ensures storage and transfer of data even on high volume applications. This powerful encryption significantly reduces the risk of access or cloning attempts and prevent counterfeit.
To further enhance the security of the chip there is a process called authentication. This process ensures that both the key card and the card reader confirm each others identity before exchanging any data. It adds a layer of security to prevent access. Additionally the chip uses a Cyclic Redundancy Check (CRC) to maintain data integrity. This mechanism checks, for errors during data transfer ensuring that the data storage transmitted from the card to the reader remains accurate and unaltered.
Triple DES Encryption
The MIFARE Ultralight C chips utilize Triple Data Encryption Standard (3DES) which is widely used in the industry as an encryption protocol. This robust method protects stored data, on the chip. Prevents access, ensuring a secure key card system that safeguards guests information.
Data Retention and Write Endurance
Offer a data retention period of up to ten years meaning that the stored data remains intact, for a decade. Additionally they have a endurance of 100,000 cycles ensuring their durability and reliability even during prolonged usage.
Mutual Authentication Process
Facilitates a mutual authentication process where both the key card and the smart card reader verify each others identity before sharing any data. This additional layer of security helps prevent access and ensures that only genuine cards can interact with the hotels system.
Seamless Usability and Efficient Integration
One of the advantages of MIFARE Ultralight C chips lies in their user friendliness.The convenience of these chips that don’t require contact makes the check in process fast and smooth enhancing the experience, for guests. Moreover they have a lifespan compared to traditional key cards making them more durable and resistant to damage.
In terms of efficiency MIFARE Ultralight C chips can work fully compatible with door locking systems such as; Onity, Dormakaba Saflok, Salto making it easier to integrate them into existing infrastructure. These chips have RFID technology embedded in them which even allows for unlocking. This feature is particularly useful in situations where maintenance staff need access without disturbing guests.
