Using the 64-bit UID in contactless RFID applications
Introduction
All STMicroelectronics contactless memory products provide a 64-bit unique identifier (UID)
for use with RFID applications. The 64-bit UID is a value written by STMicroelectronics
during the manufacturing process and it is guaranteed unique for each contactless memory.
This UID can be used by the final application system to identify each tag individually and
also, depending on the recognized memory type, to modify memory access models and
maps.
This application note describes how STMicroelectronics handles the 64-bit UID and how
applications can decode its value.
