What is mPOS? Taking card payments with a phone and a small reader

By SendPay Business · · 2 min read

Your card, ready to use
  1. Your card appears in your app
  2. Tap it to pay in a shop
  3. See every payment as it happens

mPOS stands for mobile point of sale. It means taking card payments with a phone or tablet, usually paired over Bluetooth with a small, pocket-sized card reader. Providers such as SumUp, Square and Zettle made it popular with market traders, tradespeople and pop-up shops.

How it works

  • You download the provider's app and sign up for a merchant account with them.
  • You pair the card reader with your phone or tablet.
  • You type the amount into the app and the customer taps, inserts or swipes their card.
  • The money is paid out to your bank account, usually within a few working days.

Who it suits

mPOS suits businesses that move around or take a modest number of card payments, because readers are cheap to buy and there is often no monthly fee. Busier shops and restaurants often move to a full till system with stock and staff tools.
