Download Datasheet

The MEI CASHFLOW 4-in-1 Plus validator adds the capability of contactless payment technology to traditional magnetic swipe credit/debit card, bill and coupon acceptance. MEI built upon its successful Combo validator product to create an innovative solution designed to provide maximum benefit for vending and amusement operators. This integration of four transaction methods in one product offers consumers the broadest choice in payment options. Because contactless payment is driven by NFC technology, you're ready for mobile wallet and other mobile applications available in the market today.

The Plus has a  *NEW* 3 button interface (Yes, No, Cancel) which adds the capability to interact with consumer engagement applications like loyalty programs. It also supports the ISIS Smart Tap program.

The MEI 4-in-1 Plus cashless bezel, when combined with the Advance 5000 telemeter is PCI-DSS certified, as well as EMV L1 and L2, giving operators confidence that their MEI cashless solution meets the industry standards for security. Contact MEI for further information.
