Contactless payment systems have become essential for modern retail. Whether it’s a customer tapping a phone, smartwatch, or debit card or QR code scan the expectation is simple: fast, secure, and frictionless checkout.

In the UK, this shift isn’t just noticeable, it’s measurable.
According to UK Finance:

  • 75% of debit card payments and 65% of credit card transactions are now contactless.
  • 85% of adults regularly use contactless, making it the preferred method for in-store purchases.

For retailers, this means slow payment methods are no longer just outdated; they’re costly. Long queues, abandoned baskets, and frustrated staff are often the result of not keeping up with how customers want to pay.

But it’s not just about speed. The latest contactless systems also improve inventory tracking, automate receipts, and offer better fraud protection, while supporting everything from mobile pop-ups to multi-location stores.

In this blog, we’ve handpicked six must-have contactless payment solutions for 2025, each suited to different types of retail environments.

For every tool, we break down:

  • Tagline/Value Proposition: What it does best and who it’s for.
  • Best For: The ideal retail scenario, whether you’re selling on the high street or at a weekend market.
  • Key Features + Benefits: From NFC tap-to-pay and digital receipts to reporting and fraud detection.
  • Pros and Cons: The trade-offs that matter when you’re choosing a system.
  • Pricing Overview: Transaction fees, hardware costs, and plan details.
  • Ideal Use Cases: Real-world examples to help you match the tool to your business.

Whether you’re upgrading your till, launching a new store, or switching away from card-heavy fees, this guide will help you choose the contactless system that fits your needs, without the guesswork.
