ProBio & ProFAC User Manual 57
When
Out Anti-passback
is set for a user on the master device, the last record of the user must be a
check-in record if the user needs to check in/out freely. Otherwise, the user cannot check out and the
check-out request of the user is rejected because of anti-passback. For example, if the recent first record
of a user is a check-in record, the second record of the user can be either a check-in or check-out record
but the third record must be based on the second record, ensuring that the check-in record matches
the check-out record. Note: If a user has no record, the user can only check in.
When In Anti-passback is set for a user on the master device, the last record of the user must be a
check-out record if the user needs to check in/out freely. Otherwise, the user cannot check in and the
check-in request of the user is rejected because of anti-passback. Note: If a user has no record, the user
can only check out.
When In/Out Anti-passback is set for a user on the master device, if the last record of the user is a
check-out or check-in record, the next record of the user must be a check-in or check-out record for the
user to check in/out freely. That is, the check-in record must match the check-out record.
