適用范圍：This part of EN 726 specifies payment methods for telecommunication applications, using IC cards. These payment methods are not necessarily linked to the applications which use them and they can be used by more than one application. This part of EN 726 gives guidance on the interface between the IC card and the external world, using the tools given in EN 7263:1994 and EN 726-7. This part of EN 726 considers an open system, in which the payment methods will be used. A closed system is a special case of the open system. This part of EN 726 describes the following methods of payment —pre-payment; —autobilling. For the purpose of this standard the functionality is based on: —symmetric algorithms; —diversified keys.
