A card sensor to operate the entry shutter (120) of an ATM 50 as a magnetic sensor (118) in a well (116) on the lower surface of an entry slot (110). A pair of inverted U-shaped springs (134) project into the slot (110) beyond the sensor (118). When a card (113) complying with ISO standard 7810 is inserted into the slot, the springs (134) are compressed, the magnetic stripe (132) on the card (130) contacts the sensor (118), and the shutter (120) is opened. If a thinner card, such as a telephone card or a public transport ticket (140), is inserted into the slot, the springs (134) are compressed insufficiently for any magnetic stripe (142) on the card to contact the sensor (118). <IMAGE> <IMAGE> |
