Abstract
A card reader system for reading a fare card containing data, the card being adapted for insertion into the reader; the operation is such that the card is held in a fixed position while it is being read and while other operations such as erase, write, and the like are being performed. The reader assembly is moved past the card to read the data and perform the other operations and the data representative of the amount of fare already paid is stored and a balance due or remaining is calculated and is written on the card. Preferably, the card has a magnetic stripe carrying the data, and the reader includes a magnetic head, as well as an optional thermal (marking) head. Solenoids are used to clamp in the fixed position and to eject the card after clamping is released.
