BACKGROUND OF THE INVENTION 5th paragraph
In many systems which currently employ smart cards, the number of users can be quite large. For example, in an electronic banking system, a considerable number of customers might be expected to access an automated teller machine each day. Consequently, the cost of the reader is amortized over a sufficient number of transactions that it can be readily justified by the provider of the services.
