Yes, Ingenico terminals used in vending machines are designed to be agnostic when it comes to payment processing. This means they can support a variety of payment methods and integrate with different payment processors or acquirers. This flexibility allows vending machine operators to choose the payment processing solution that best fits their needs or geographical location, including credit and debit cards, mobile payments, NFC (contactless) payments, and QR codes. It ensures they can adapt to changing consumer preferences and regulatory requirements without needing to replace their entire payment infrastructure.
