TM card is similar to a button battery in shape and can be inlaid into a card, key button and other objects.

You can replace the data line, address line, control line and power line with a single line so that TM card achieves single line communication through a multi -function device.

According to whether the Memory in TM card is encrypted or not, TM card can be divided into encrypted TM card and non-encrypted TM card. Most of TM cards are non-encrypted.


TM card’s encrypted method is different from Contactless IC Encrypted cards: The former has 64-bit password without the function of error calculation, while the latter has shorter password and the function of error calculation.

If you forget your password by chance, you can reuse your TM card after re-initializing it, but the information in your card will be automatically rewritten.
