Tcard is based on smart card technology. A chip embedded in the Tcard communicates with the card reader through RFID induction technology (at data rates of 106 to 848 kbit/s). These cards require only close proximity to an antenna to complete transaction. They are often used when transactions must be processed quickly or hands-free, such as on mass transit systems, where smart cards can be used without even removing them from a wallet.

Like smart cards with contacts, contactless cards do not have a battery. Instead, they use a built-in inductor to capture some of the incident radio-frequency interrogation signal, rectify it, and use it to power the card's electronics



would it be hard to construct an antenna for the smartcard?

^ my thinkpad has an rfid chip built in for inventory, you can buy the readers on ebay or from surplus electronics places

just an interesting point

would a reader be able to rewrite info on the smartcard?

I guess some of them would, there are different models.

here are some threads,

somewhere in that forum is a link to a place that sells the reader. I want to get the one in my computer out, it is sort of fucking creepy.

whats wrong with the one in your computer?

what do you think? it might be transmitting weird shit that I can't control
