The future of payments is convenience. As we move further into the age of contactless payments, which accounted for a total transaction value of $8.75 trillion in 2025, being able to accommodate the growing preference for contactless cards and mobile payments (e.g. Apple Pay, Google Pay) is crucial, even for SaaS businesses.
Tap to Pay is no exception. In 2026, your smartphone isn’t just where you manage your business – it is your credit card terminal. It’s the extension of your storefront, whether you’re on the go, on the sales floor, or linebusting at the front desk.
With a simple tap, this payment technology removes the friction of dated, clunky hardware, helps streamline operations, and encourages instant, on-time payments.
How Tap to Pay works
Simply put, Tap to Pay uses near field communication (NFC) – a short-range wireless technology – to accept in-person, contactless payments from digital wallets, as well as contactless-enabled cards.
This is a hardware-free payment method, meaning merchants/techs do not need any extra attachments to accept a payment. All they need is their Apple device and a Tap to Pay app or SDK (now available with Stax).
Tap to Pay is a secure payment solution. In fact, through tokenization and encryption, tapping is now safer than swiping, as no card details are ever exchanged.
