A portable device is provided which enables a customer at an automated teller machine (ATM) to avoid being victimized after the customer has inserted a user's identifying card into the ATM. The device comprises an activatable transmitter which, when activated, triggers a sensing device at the ATM. Preferably, the transmitter includes an infrared emitter which emits an infrared signal when the transmitter is activated. The switch can be activated only when a user's identifying card containing encoded customer information is inserted into the ATM. |
