Help CenterNFC (Near-Field-Communication) is basically a technology that enables data transfer between two compatible devices by allowing data to move between them. NFC is utilized in the credit card processing business to swiftly and easily wirelessly communicate sensitive credit card data while maintaining security.
NFC is a technology that's been in mobile phones and tablets for a while now, making it an industry standard. Apple Pay is Apple's "version" of NFC. Google has its own version, too - it's called Google Wallet. Fundamentally, it's the same thing - both companies are using NFC to send short, secure communications between two devices. The communications only pass a few feet - hence the name “near field”.
In order to accept payments from other NFC devices, such as Android (Google) phones, Apple iPhones, Apple Watches, and Google Wallet devices, it is crucial for merchants to have NFC-capable hardware. Consumers are embracing NFC-capable gadgets at an increasing rate, and as a result, they'll want to start making purchases using those devices.
