A company in Australia called NoahFace has created software for cafes that remembers customers' faces and their favourite drink.Founders Geoff Cropley and Julie Buchanan thought of the idea after opening Bahista Cafe in Sydney three years ago.They teamed up with coder John MacLean and he wrote the software for the facial recognition system, reports the Daily Telegraph.It uses two iPads at the cash register – one looking at the customer and the other at the staff.When a customer walks in it recognises their face and tells the staff their name and regular order.Customers also don't have to carry loyalty cards as their purchases are logged on the computer system.
