Anti-metal super light C NFC QR code sticker use Ultralight C chip. The chip is the first of its kind to introduce open standard 3DES encryption technology for authentication and anti-counterfeiting of one-time ticket solutions. It is very suitable for prepaid applications such as gift cards, coupons, and limited use of tickets. Other major advantages of Ultralight C include: 

Security

● 3DES Authentication

● Anti-cloning support by unique 7-byte serial number for each device

● 32-bit user programmable OTP area Field programmable read-only locking function per page for first 512-bit

● Read-only locking per block for the memory above 512 bit

Anti-collision

The intelligent anti-collision function allows operating more than one card in the field simultaneously. The anti-collision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without interference from another card in the field.

The anti-collision function is based on an IC individual serial number called Unique identification. The UID of the MF0ICU2 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3.

Other Advantages

● 1536 bits (192 bytes) EEPROM

● 16-bit counter

● Data rate: 106 KB /s

● NFC Forum Tag 2 compliant

● Double version available: 17pF for ID-1 size tickets; 50pF for smaller labels
