LRIS2K_08 Datasheet, PDF (63/102 Pages) STMicroelectronics – 2048-bit EEPROM tag IC at 13.56 MHz, with 64-bit UID and Password, ISO15693 and ISO18000-3 Mode 1 compliant

Select
When receiving the Select command:
● if the UID is equal to its own UID, the LRIS2K enters or stays in the Selected state and
sends a request.
● if the UID does not match its own, the selected LRIS2K returns to the Ready state and
does not send a request.
The LRIS2K answers an error code only if the UID is equal to its own UID. If not, no
response is generated.
