Payment method, payment system and suitable devices therefor

摘要

The method involves transmitting credit document data of a document data memory (151) of a mobile terminal (1) of a user to a proximity area-interface (21) of a service terminal (2) over a proximity area-interface (11) of the mobile terminal. Debit data on the service terminal is adjusted based on the credit document data and based on product and services. The debit data is transmitted from the service terminal to the mobile terminal over the interfaces, and a signal is provided for enabling the product and services based on the transmission of the debit data by the service terminal. An independent claim is also included for a payment system for payment of product and services.
