Technology moves in leaps and strides. Just a few decades ago, most people had never heard of credit cards: carrying around tonnes of cash was essential. Now it’s hard to imagine our lives without those little pieces of plastic that make life so much easier.

The device scans the magnetic strip on the back of a credit card for payments wherever and whenever.
