Fibank has increased the security level of teller operations in its office network by introducing additional customer identification using customer’s bank chip cards and smart card readers attached to the teller’s work stations. The Synergy GFS Card Security solution prevents tellers in the office to initiate any kind of transaction with the customer’s accounts without presence of a customer’s bank card issued by the bank and successful offline PIN validation. The solution effectively prevents identity theft and internal fraud with customers’ funds.
