WHAT IF YOUR FACE IS A TRIGGER? We are all getting used to the idea of facial recognition. Where it used to be digital cameras that would fi nd the position of your face and what to focus on, now this technology has upgraded immensely. Think about it, you can pay for things by simply using Face ID. What can we expect in the future? From barcode to RFID and Face ID We are familiar with barcodes. You put your groceries on the conveyor-belt and the cashier scans the barcode of each product. After that you put your groceries in your shopping cart and you pay for the scanned items. As it may sound like a diffuse system, it is much more advanced than having to memorise all product prices separately. While only a small amount of information can be stored on a barcode, it can be called old-school anyway. Radio Frequency Identifi cation (RFID) is a much more advanced technology. These are very small chips that can be scanned from a distance. Depending on the type of RFID chip, it can channel a signal on its own. This practical example will give you a better idea of what this technology entails: Chances are you use it daily: a debit card which allows proximity payments, enabled by the RFID chip inside of the hardware. When you hold your card near a pay terminal that is RFID compatible, the amount will be withdrawn from your account. If you reached your daily limit, the card will make you use your pin code for all other payments that day. Amongst others, entrance badges, keys and public transport chip cards make use of this type of technology as well 28- CONTINEW
