Thin Proximity LF 125kHz RFID Cards
Introducing the Thin Proximity LF 125kHz RFID Cards, a battery-free option for Contactless data transmission and energy supply. Its operating range can reach up to 100mm, subject to antenna geometry. This versatile card functions at a frequency of 125KHz and boasts a data transfer speed of 106 kbit/s.

This card offers Data integrity of 16 Bit CRC, parity, bit coding and bit counting to ensure Anti-collision. It is commonly used in ticketing transactions that can be completed in <100 ms, including backup management. The applications for this card vary from public transportation to access control to event ticketing to gaming and identity. Some notable features include: contactless data transmission and power supply (no battery necessary), anticollision capabilities, an EEPROM with 1Kbit organized into 16 sectors with dual passwords for each sector, customizable access conditions for memory blocks, a data retention period of 10 years, the ability to withstand 100 000 cycles of writing, enhanced security measures such as individual key sets for each sector and a unique serial number for each device. Additionally, there is a transport key that safeguards access to the on-chip delivery of the EEPROM.
