Then financial account holder submits his/her request to a transaction counterpart along with the EPSL account number and the alphanumeric signature, generated by financial institution EPSL during previous authentication session.

The accounting session starts at the end of the authentication session and finishes along with the authorization session while being an essential part of them both. The system and method are particularly suited for use by banks, credit card companies and brokerage companies. Finally, the system and method are well adapted to the current an d upcoming software, hardware, and electronic commerce technologies and can be easily implemented given an acceptable business trade off.</p> |
