A reader for a card having an information strip, the reader comprising a first movable member, a read head capable of reading the information strip, the read head disposed on the first movable member and a second movable member which upon translation causes the first movable member to translate in a direction opposite to the second movable member. The reader includes a guide slot disposed in line with the direction of translation of the second movable element such that when a card is placed in the guide slot and subsequently moved transversely along the guide slot, the card urges the first movable member in the opposite direction and moving the head across the information strip as the information strip is moved in the opposite direction as the read head movement.

1. A method of using a reader for a card having an information strip, the method comprising:
providing a first movable member; providing a read head capable of reading the information strip, the read head disposed on the first movable member; providing a second movable member which upon translation causes the first movable member to translate in a direction opposite to the second movable member; providing a first member groove wherein the first member is slidable in the first member groove and a second member groove wherein the second member is slidable in the second member groove; providing a guide slot disposed in line with the direction of translation of the second movable member such that when a card is placed in the guide slot and subsequently moved transversely along the guide slot, the card urges the first movable member in the opposite direction and moving the head across the information strip as the information strip is moved in the opposite direction as the read head movement; ensuring the card reader is in an initial condition wherein the read head is adjacent to the second movable member; placing the card within the guide slot with a portion of the information strip positioned adjacent the read head; and urging the card in a direction to move the second movable member until the read head moves relative to and along substantially the entire length of the information strip.
