I can recommend Sumup as another way to take payment using a mobile card reader. It makes you look more professional taking electronic payments rather than cash or cheques. It's a great bit of kit and easy.
It's a good idea to let customers decide which payment method they prefer.
I use the Sum Up card reader to take payments by card on the road. Really low rates less than 1.69% with no fixed fee or monthly fee. Much better and cheaper than paypal. You can also take payments over the phone too.
The card reader can be purchase with a discount using this link reduced from £30 to just £15. ( also helps me with referral reward )

Once you take payment you then can put the customers email or phone number in the app and it will either text or email the receipt straight away for them. Works a treat.
Just use your own card to test it out when you get it first to see how it works. Just take £1 on your own card
