What is the recommended Apex RFID BurstBuster approach to security?
When library materials are checked out, either at staff or self check-out stations, the tags security bits are disarmed. The security bit is, however, different from any other bits on the tag. This unique TAGSYS tag feature uses a dedicated EAS (Electronic Article Surveillance) burst at 106 KHz. This EAS burst is issued only if the EAS bit is set to the on position (which it would be unless it has been turned off during a checkout). It does not require a wake-up signal and is therefore a Tag Talks First (TTF) type of modulation. The functional effect of this is that the security gates only detect security bits in the “on” position; they do not attempt to read each tag to determine if the bit is on or off. This keeps the detection rate of the TAGSYS system at consistently above 95% regardless of the number of items that are in the field. All other RFID systems are based on “Reader Talks First” (RTF) type of modulation. The security gates are attempting to read every tag in the field in
