Ultra-light C ULC Keyfobs NFC keychain

Dimensions: 40mm x 30mm x 4mm, small size. These ULC token key cards are made of ABS material, which is waterproof, drop-proof, high temperature resistant, stable and durable, and has a long service life. Strictly follow the ISO14443A communication protocol and ensure that the card reader supports the communication protocol and Ultralight C extensions (such as 3DES authentication). Long-term exposure to high temperature (> 60°C) or high humidity may cause wafer failure.

Compatible: Compatible with the newly upgraded SAFLOK, KABA, ONITY and SALTO locks. Not compatible with AMIIBO and 125kHz readers. This  ULC keyfob MF0ICU2 can be used with most access control security systems. Some access control/door lock systems (e.g. SAFLOK, KABA) require a special key format and cannot directly reuse cards from other systems. [Note: If you want to add a ULC keychain to your locking system, please make sure your system frequency is the same]

Chip: Ultralight C MF0ICU2 chip, operating frequency: 13.56 MHz, 192 bytes of available memory. Each device is protected from copying using a unique 7-byte serial number that cannot be changed or rewritten. 32-bit user programmable OTP area. The first 512 bits of each page can be field-programmed with a read-only lock function [Note: NFC Tools and other applications can read the serial number of the ULC keychain]

Authorized entry: The administrator enters the key's unique identification number into the access control system database and associates it with specific personnel and area permissions through a dedicated card reader device and management software. In the company's access control system, employees' key fob serial numbers and employees can enter office floors, specific rooms and other authority restrictions.
