Transaction product with generator

Abstract

A transaction product includes an electro-mechanical circuit and an account identifier. The circuit includes a mechanical drive member, a generator in mechanical communication with the drive member, and an electrically driven device in electrical communication with the generator. The circuit is configured such that when a bearer moves the drive member, motion from the drive member is transferred to the generator, the generator uses the motion from the drive member to create an electrical voltage, and the electrical voltage is transferred to the electrically driven device to selectively power activation of the electrically driven device. The account identifier links the transaction product to an account or record and is machine readable by a point-of-sale terminal such that value can be added to or deducted from the account or record using the account identifier. Other cards, products, assemblies and methods of using such cards, products and assemblies are also disclosed.
