Abstract
A financial transmission method utilizes smart cards with radiofrequency communication between the central station and the card so that the smart card is periodically or continuously updated as to account details which can be readily seen by a display on the card. The card, which otherwise has all of the size and dimensions and shape and embossability of a conventional credit card, debit card or ATM card also has the usual magnetic stripe-bearing information as to the card and the account to be debited or modified.
