What is the cheapest way for people to pay you if you're a very small business

[LaurieFairyCake]

I’m looking for an app I think? Or a barcode on my phone they can tap. I’m not keen on PayPal and I’m a bit behind the times with stuff

I’d really like a card machine - any idea of the costs of it?

What's your estimated turnover?

Have a look at the izettle: www.izettle.com/gb

I'd echo izettle, had good experiences with it including dealings with their customer service line. (I sold at craft fairs etc). There are a few other options to investigate. All supply little card machines that connect via your phone usually via bluetooth:
Sumup; Square; Payleven; Paypal Here (pays into your paypal so maybe not this one if you aren't keen, and seems to have higher fees)
I think they all do chip and pin now and you can email receipts.

izettle seems to be about £30 for the card reader and then transactions are charged at 1.7% each. Sumup looks similar. Total bargain IMO. Obviously you need a data connection but I've never had an issue with this; if you live in the depths of nowhere you may though....

depends what you are selling, who to and on what occasions

My hairdresser who works from home has one of those. It seems to work well.

I have clients that use izettle and it is cheaper than a paypal machine (1.75% compared to 2.75% for paypal from memory).

It works well for them.
