Two-tier pricing improves your ROI with the ability to charge two different vending prices with the Iris Reader. A standard price for credit/debit purchases to offset the cost of card procession, and a discounted price for cash. The machine also offers the choice of swipe, bezel, contact or contactless to accept payment. The multi-vend capability allows for more purchases. The system has voice prompting for an enhanced experience, and multi-lingual capabilities.
