By means of the response of the SELECT (UID) command the RWD detects that the HITAG S Transponder is configured
in Authentication Mode (Bit AUT = 1) and starts the encrypted Challenge sequence.
The Read/Write Device sends a 32 Bit Random Number (RND) and a 32 Bit secret data stream to the transponder. In
order to perform the secret data stream, a security co-processor is required on the read/write Device. For more
information please contact us at - [e-mail].
If the received secret data stream corresponds with the secret data stream calculated by the HITAG S Transponder, a
32 Bit Secret Response (secret data stream encrypting the configuration byte CON 2, password high byte PWDH 0 and
password low Bytes PWDL 0 and PWDL 1) is transmitted after the SOF.
The response of the HITAG S Transponder is transmitted in Manchester Coding (MC).
Table 21
A HITAG S Transponder configured in Authentication Mode changes from Authenticate State into Selected State only
after a correct CHALLENGE Sequence.
Note: Even with AUT=1 further data transmission for read and write commands is done in plain mode.
