Main characteristics
TM card is a kind of encapsulated in su304-0.3 stainless steel shell of smart card, strong and durable, corrosion resistant; Ultrasonic welding, waterproof performance Good. Within the semiconductor wafer with lithography 64bits ROM code, each product only, no repeat. Surface laser carving serial number, and the product Logo. Support all single bus mechanism, which can realize multiple card to read.
Password capacity of 280 trillion, door locks mutual opening rate of zero; It can be embedded in the PVC card, extremely easy to carry, gwydn; Touch operation, free of high-frequency electromagnetic interference;
Cost efficient; TM card reader’s price is only 1/3 of IC card reader, 1/10 of the non-contact type IC card reader head; While they perform the same function, TM card reader device has the lowest cost among all;
100 times of service life comparing with contact type IC card reader head, 10 times comparing with that of contactless IC card reader the head. Not necessary to replace the reader head.
