6.4.2
Withdrawing read/write authorisation
Read/write authorisation must be withdrawn in the following cases:
•
If no more data is to be written to write-protected segments of a medium.
•
If reading from read-protected segments of a medium is no longer to be read.
In this chapter, the term ‘write authorisation’ shall be used to refer to both ‘write authorisa-
tion’ and ‘read authorisation’.
6.4.2.1
Withdrawing all write access issued via a write authorisation
Reset the device to factory settings. (See chapter Maintenance)
6.4.2.2
Withdrawing individual write access issued via a write authorisation
The withdrawal is carried out via a regestration unit.
Requirements
•
For cancelling the write authorisation, a SAM 64 card with the corresponding segment
zone is required.
•
The device and the registration unit are ready for operation.
Procedure
1.
Present the master medium.
ð
A brief signal sounds and glows green briefly.
2.
Present the SAM 64 card uninterrupted to the compact reader (approx. 15 s).
ð
The regestration unit glows green during the process.
ð
3x beeps: Write authorisation was cancelled
If write authorisation has already been revoked before with the same SAM 64 card,
this is signalled immediately with three beeps.
ð
No signal: Write authorisation has not been revoked.
Possible reasons
- The SAM 64 card was removed from the RFID field too early
- ISO 14443A is not activated in the system
- If using SAM+ media: there are no credits available
3.
Remove the SAM 64 card from the field.
