There aren’t any truly free card readers for growing businesses. Whichever way you slice it, you’re going to pay more in transaction fees, device rental, or other ongoing charges for the privilege of taking payments.

But when you think about the complexity of the global payments system, the tech required to keep you and your customers safe from cybercriminals, and the speed and seamlessness of processing, it’s a small price to pay to do business.

That said, with the right setup, it’s possible to limit your card payment costs — particularly if you understand how pricing structures affect your costs as your turnover increases.

Below, we look at device and transaction fee pricing models, how to get the best deal for your business, and some of the best value card readers out there.

How do card reader costs work?

Monthly fees are common, but they’re not universal. Many providers sell card readers outright and then charge transaction fees on a pay-as-you-go basis, with no ongoing subscription. Others charge a monthly fee, either to rent the machine, or on top of the purchase cost of the device in exchange for benefits like lower rates and enhanced support.

The trade-off is straightforward: higher fixed costs in exchange for reduced per-transaction fees and extra services.

For example, a monthly subscription that looks expensive at first glance can work out cheaper than a no-monthly-fee option once you’re processing a higher volume of transactions. The key is thinking in terms of long-term cost, not just upfront spend.
Below, we look at the main pricing models available — from flat rates to bespoke pricing — and how pay-as-you-go compares with subscription-based plans.

Here’s a breakdown of pay-as-you-go vs pay monthly models.

Pricing model	Advantages	Drawbacks
Pay-as-you-go	No ongoing monthly fee, so costs flex during quieter trading periods No long-term contracts or exit fees Flat-rate transaction fees make costs simple to forecast	Transaction fees are typically higher than on subscription plans Costs can rise quickly as payment volumes increase
Subscription pricing	Access to lower or tailored transaction rates, which can significantly reduce costs at higher volumes Added benefits such as faster terminal replacement, priority support or enhanced features	Monthly fees apply regardless of sales performance Transaction fees can be variable and harder to compare Contracts often run for 12–18 months, with exit fees for early cancellation Additional charges may apply for setup, maintenance or optional add-ons

Best value card readers for growing businesses

For growing businesses, value isn’t just about the lowest headline rate or cheapest device – it’s about flexibility, and particularly the ability to access better pricing as volumes increase.

If your turnover is rising or predictable, tailored pricing and lower per-transaction fees can deliver meaningful savings over time. If revenue is still uneven or seasonal, flat rates and pay-as-you-go pricing may offer better cost control.
