Abstract

A low cost, low power consumption pager of approximate credit card size which can serve as both a pager and a credit card or telephone calling card. The pager is powered by a flat, flexible battery, and is comprised of low power consumption pager circuitry. The circuit is turned on and off at regular intervals to converse energy. The pager holder is altered to incoming messages by a combination of audio and visual signals. The pager can be activated or deactivated by itself or in concert with other pager devices by a single cell. The pager includes a magnetic strip, or the like, for encoding identification and security data and for performing account verification. The audio circuit on the pager can emit audio signals of varying pitch and amplitude, each combination representing a distinct class of messages. Each pager can emit a unique sound distinguishing that pager from all others in a group. The circuit responds to signals for overriding the reception of messages and for turning off the audio cirucit, if circumstances warrant it.
