Free Square Card Reader (to take payments on the go) - Normally these are £15-£18. Note: It’s a 1.75% transaction fee for all sales so whilst it’s free you’re charged a fee for each use. No monthly charge though so ideal for any small businesses / sole traders that don’t do a lot of in-person card purchases.
