You might have seen the images of Amazon Go, a futuristic grocery store where a vast array or sensors keep tabs on what items shoppers pick up in real-time. As a result, customers are able to buy food & drinks on the go, simply by taking products out of the shelves and leaving the store. No cash register. No employee. No queue. And no debit card. Albert Heijn now introduces high-speed shopping in The Netherlands: Tap to go. Comparable, but possibly more efficient and innovative when it comes to high speed shopping.
