Imagine this: You’re stuck on the phone with a customer. The other sales person has stepped out for lunch when suddenly a shopper walks in and heads straight to an item on display. You really want to serve him but the customer on the phone is important too. You glance over and see that the guy has lifted the tag and looked at the style name, product description and price.
Lucky for you, there’s something more imprinted on the price tag, a square-shaped barcode called a QR code. The customer sees this, grabs his smart phone and aims it at the QR code.
