I went to a shop a while back and when I was ready to pay, I asked if they take bank cards. The person at the counter said yes, so I handed over my card. She proceeded to plug something into her phone, and swiped my card.
How safe are these things? I imagine only as safe as the person's phone (which probably isn't very safe with most people).
If I had known what she was using, I probably would have used another form of payment.
