Retail giant Walmart is introducing a digital receipt service across its 4,200 US stores, enabling shoppers to store a digital version of their receipt in a mobile app by scanning a QR code shown on their paper receipt or by entering their mobile number at the point of sale. Customers will then be able to use the receipts to create a shopping list on their device, making their in-store experience “easier and more convenient”.
Ten years ago, we opened our building’s front door with a badge. Five years ago we paid public transports with an RFID card. Today we pay for our bread with the same system and tomorrow we would probably be able to authenticate ourselves with something similar.
In today’s society, technology is everywhere. If you thought there couldn’t be any more technology that you need to deal with, you would be wrong. In fact, there will probably never be a time when there is not some new innovation that you have to think about in the future. The question that you should always consider, however, is this: should we be using that technology and is it safe and secure to use? This brings us to a recent technology that has come out over the past few years – Tap and Pay.
