All Cryptags® can be simultaneously interrogated without losing fidelity. The RF communication between each Cryptag® and reader is scrambled to eliminate the chance of simulated tokens being used. Active (battery powered) Cryptags® offer real 'hands free' ranges in excess of 1.5 metres.
Cryptags® patented technology offers many benefits to systems designers, integrators and end users. Not least of these is that the tags do not interfere with other electronic surveillance systems causing false alarms etc. The typical error rate for Cryptags® is 1:10 million in worst case noise, this is significantly better than most other tag systems. Cryptags® are manufactured with a programmable 31 bit code, strict factory audits ensure no two tags are issued with the same ID number.

Active Cryptags® have a shelf life of 7 years or greater stored at 20ºC. Operational life is dependent upon usage. However based upon 36 uses per day of 10 seconds each, or 6 minutes continuous interrogation per day, typical life at 20ºC is 3 years or greater. Intrinsically safe tags and bespoke tag designs are available from Identec.
