Standard Change-Makers Bill Exchangers are a versatile mix of Bill-to-Bill Exchangers and Bill-and-Coin Exchangers. Designed to help self-service business owners break larger denomination bills, like $20 bills, into more manageable, smaller denominations (like $5 bills), without making customers fill their pockets with coins. The Bill Exchanger Series uses your choice of the UniNote Bill Dispenser or the Fujitsu Single or Dual Note Bill Dispensers - and the BCX models are coupled with our reliable coin dispensers and Modular series controllers. Our Bill Exchangers are designed to help alleviate the need for attendants, or assist in your business security by taking the cash out of your attendants hands.
