Here at UEA over the past few months, we have experienced an intermittent problem with the security EAS bit on some of our RFID tags being locked permanently on INACTIVE on a small percentage of our items. It is then impossible to make security ACTIVE again. The outcome is that any tags affected have to be removed and replaced. We are keen to hear from any other sites that have experienced such issues because the definitive cause has not been found.
