Mobile card readers, explained

If you sell on the go, you don’t need a full terminal. Here’s how mobile card readers work and how to pick one.

Square Reader (contactless)

What a mobile reader is

A small device that pairs with your phone or tablet to accept tap and chip payments through a POS app. It’s the lightest, cheapest way to take cards — ideal for pop-ups, markets, services, and anyone who sells away from a counter.

The main types

Plug-in / Bluetooth readers (like Square Reader or Clover Go) pair with your phone for tap and chip. All-in-one handhelds (like Square Terminal, PAX A920, or Dejavoo P3) add a screen and a built-in printer so you don’t need a phone at all. Tap to pay on phone is also an option on some devices.

How to choose

If you just need to take an occasional card, a Bluetooth reader is perfect. If you take payments often or want to print receipts and run a real menu, step up to an all-in-one handheld. (See our terminal vs. POS guide for the bigger picture.)

What the savings fund

Cutting your card fees is step one. Here is what the savings fund.

Lowering what you pay to accept a card frees up money every month with no extra work and no new customers.

What about fees?

A mobile reader works the same on a zero-cost program — dual-pricing shows the cash and card price, so your processing costs are covered. The reader itself is provided at $0 up front.

Questions

Frequently asked

Can I take payments on my phone?

Yes — a mobile reader pairs with your phone or tablet, and some devices support tap to pay directly.

Do mobile readers print receipts?

Bluetooth readers send digital receipts; for printed receipts on the go, an all-in-one handheld with a built-in printer is the better choice.

Is it secure?

Yes — mobile readers use the same EMV chip and NFC security as countertop terminals.

What the savings fund

Cutting your card fees is step one. Here is what the savings fund.

Lowering what you pay to accept a card frees up money every month with no extra work and no new customers. The businesses that grow from there spend it on the three things that actually bring customers in: answering every call, a site that converts, and showing up on Google.
