Paypal are working on a concept for the new Samsung smart-watch which will allow customers to pay for products in store using their watch. The idea is that the customer checks into a shop using the watch and then pays for the items with the "wearable" smart-watch. The watch features Bluetooth Low Energy (BLE) which will enable the device to check-in to a beacon located by the point of sale and pay. The concept also allows the customer to view transaction history, check balance and view offers in the stores the customer frequently visits.
