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. When the host is
powered, TM card gives the response to the host through switching
the impedances between 50Ω and 500,000Ω. The lengths of time the
signal is pulled down(long or short) show the digital
logics(long=1, short=0). Due to the range of witching impedances is
1-10,000, the resistances of the contact points will not affect the
identification of the digital signals.
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.
