Square, the independent mobile payments service, is taking on PayPal's Here bank card reader with some upgrades of its own. The name 'Card Case' is gone and has changed to 'Pay with Square' instead. The new iOS and Android app offering will also point you in the direction of nearby shops where you can pay with Square via a map view – though the number is not huge in the UK right now.
Have you used a simialr offering yet ? How has it worked for you?
