A memory device 30 allows a person to remember only a single code and use that code to retrieve the identifying code or password required to access a secure facility. The memory device 30 is nearly the size and shape of a credit card and has a display 32, keypad 34, and housing 44, which may be tamper-proof, having a writing portion 46 on the rear. A user initially uses the keypad 34 to enter both a memory access code and a separate identifying code associated with each secure site or equipment. Subsequently, when the user desires to access a selected site or equipment (s)he can enter the access code and read, from the display, the required identifying code. A mnemonic descriptor can be written on a designated blank writing portion 46 on the housing, for each stored code. A brief advertising message can also be stored in the device memory and displayed each time the device is turned on. In a preferred embodiment, all the stored identifying codes are erased after a predetermined number of sequential inputs of the incorrect access code. |
