Pagers having extremely small form factors such as credit card pagers are typically powered by coin shaped batteries which have low capacity and high internal resistance in contrast to the AAA and AA batteries commonly used for other pagers. As a result of the choice of form factor and battery for a credit card pager, room inside the pager does not exist for a vibrator, and furthermore, the battery inside the pager could not adequately drive a vibra- tor. There are customers who would, at times, still like to be able to use a vibrator accessory for their credit card pagers. The problem, then, is how to provide a vibrator function for credit card or other pagers having insufticient internal space and insuf- ficient internal battery capacity.
