The Model 899MAX Three Column Electronic Drop-shelf Vender can vend many different types of products, each with their own pricing. The large Dot Matrix display is the defining feature of the new DigiMax machines. Customers are prompted with easy to read instructions as words scroll across the display. Vend prices can be set from .25¢ to $99.75. The optional Cryptopay credit card swiper will open up new ideas in vending higher priced products (bags of tokens, headlight repair kit, etc.) – just plug it in to the built in port. MDB ready means any of the credit card systems can operate without additional hardware. Operates on 24 volt AC power, transformer not included.
