Accepting credit card payments

[Sensible24]

What do you call those things that people attach to devices like mobile phones and tablets to be able to accept credit card payments? My sister and I saw one the other day and she'd like one for her business.

I think the most used one is called "Square" so google "iphone square credit card reader" or something like that.

To accept a credit card payment using a mobile or a tablet , I remember a friend who uses a POS system.

I think I remember someone calling it a dongle in a fair. I'm not really sure though.

If you are familiar with Tsys, they have that kind of POS and they offer free credit card readers. Is that the right one?
