14.10 SELECT

[Advanced, Advanced+]

The SELECT command is always be executed with SEL flag set to '0' and ADR flag set to

'1'. There are several possibilities upon reception of this command without error:

• If the UID, received by the transponder IC, is equal to its own UID, the transponder IC

enters the Selected state and shall send a response.

• If the received UID is different there are two possibilities

– A transponder IC in a non-selected state (QUIET or READY) is keeping its state

and not sending a response.

– The transponder IC in the Selected state enters the Quiet state and does not send

a response.

Error Flag set to ’0’ indicates no error.
