The new GBA ST1 offers a new dimension in bill acceptors. It is a cost-effective, compact note stacker unit.  With a robust plastic construction, the ST1 can be used in either an up or down stacking orientation and has the option of lockable cashboxes, to maximise cash security. To accommodate slim-line machine designs, the ST1 can be configured to be situated in depths as limiting as 10cm.   The ST1 offers a variety of interface options including the MDB vending protocol and CCTalk.   Flashing note guides have been introduced to provide more obvious and user friendly interaction whilst an innovative new discrimination method, “Sense Technology”, has been developed to provide high level acceptance of true notes whilst maintaining security against counterfeit and fraud attempts.   The ST1 delivers the performance and functionality previously restricted to top end note validators, at a price to suit most budgets.
