The LRI64 is a contactless memory, powered by an externally transmitted radio wave. It contains a 120-bit non-volatile memory. The memory is organized as 15 blocks of 8 bits, of which 7 blocks are accessible as Write-Once Read-Many (WORM) memory.

The LRI64 is accessed using a 13.56 MHz carrier wave. Incoming data are demodulated from the received Amplitude Shift Keying (ASK) signal, 10% modulated. The data are transferred from the reader to the LRI64 at 26 Kbit/s, using the “1-out-of-4” pulse encoding mode.
