Select

When receiving the Select command:

•

If the UID is equal to its own UID, the ST25TV02K/512 enter or stay in the Selected state and sends a

response.

•

If the UID does not match its own UID, the selected ST25TV02K/512 return to the Ready state and does not

send a response.

The ST25TV02K/512 answer an error code only if the UID is equal to its own UID. If not, no response is

generated. If an error occurs, the ST25TV02K/512 remain in its current state.
