Standard Change-Makers has been in the business of designing and manufacturing currency change machines since 1955. Beginning with simple mechanisms that changed half-dollars to quarters, dimes and nickels - up to validating $1 through $20 bills and providing change in bills & coins, or tokens, tickets or cards. Standard Change-Makers has been on the forefront of innovation and change in the industry. Our product line features "simple function" machines that provide simple change for coins, to more "sophisticated" transactions like firing a car wash or washing machine, or accepting a credit card and using cellular signal to process the transaction and then dispense tokens or tickets or wristbands. Our reputation is based on the security of our cabinets and the longevity of our products. Our cabinets feature heavy gauge steel cabinets with solid weld lines. Our hoppers have steel housings and metal gears to provide many years of service. Many of our machines have been in service for 20+ years and have millions of cycles on them, and are still in use today. Working with Distributors throughout the U.S, Canada and Mexico - Standard Change-Makers products are serving business owners by providing more payment convenience for their customers.
