The Chip&Pin SL31 mobile card reader can be connected to a retailer’s smartphone or tablet PC via Bluetooth or a USB cable. In order to make a payment, customers insert their debit or credit card into the lower slot of the card reader and enter their PIN code or signature on the 2.4” colour touchscreen. The touch-sensitive display enables the mobile card reader to be used in a way similar to a smartphone. The device is so small and flat that it fits into any trouser pocket.
