Batch transaction authorisation

摘要

A method and system (1000) for conducting batched transaction authorisations from a mobile device (1070) is disclosed. The method includes transmitting a batched transactions list including details of multiple transactions loaded against an account and awaiting authorisation, to the mobile device (1070), over a secure connection (1110) between an authentication server (1060) and the mobile device (1070), and receiving a batched transaction authorisation message from the mobile device over the secure connection including a positive or negative authorisation result in respect of two or more of the transactions in the batched transaction list, each authorisation result in the batched transaction authorisation message having been individually signed with a private key (1090) associated with a unique digital certificate (1080) of the mobile device (1070).
