It was first started by Amazon Fresh I believe.
Now Tesco are trying to do the same with their first check-out free store.

Basically you cannot physically get into the store unless you have the Tesco App. You also cannot pay by means of cash or a credit/debit card - you are made to pay for your purchases through the App.
Isn't this potentially discriminatory plus it forces customers to fit into their ecosystem and comply with their restrictions?
This particular store is in an area with many council flats nearby. Elderly and disabled people used to shop there and will now need to walk at least 15 minutes to do their shopping.
Where are we heading with all of this? Shouldn't we have more options and freedom not less?
