Abstract: A computer implemented system and method for multi-level transaction authorization in a banking support unit. The system includes a data center with a cluster further including: (i) a host for processing transactions, (ii) a security module authenticating and generating a customer personal identification number (PIN), authentication means for authenticating a point-of-sales (POS) terminal, and encryption means for encrypting all information and POS transactions. The system further includes a maker-checker unit further comprising: a token number generator for conducting sensitive transactions on said POS by unique tokens validated for adaptability with said cluster; and an authorization cards array to configured to effectuate multi-level authorization of primary and subsidiary transactions while selectively linking said primary and subsidiary transactions to said token number generator.

Abstract: A system and a method for authenticating financial transactions on PUS terminals have been disclosed. The system 100 authenticates the financial transaction by displaying a user's signature, at the time of a transaction, on the POS terminal. The display of the user's signature on the POS terminal not only acts as a secure access image for users to guarantee a secure payment channel but also proves the authenticity of the remote application servers associated with the financial institutions making the financial transactions at the POS terminals safer and secured.
