Tesco shopper shares trick to unlock supermarket trolleys without a £1 coin

A Tesco shopper has shared an easy hack to unlock a trolley if you don't have a £1 coin on-hand.

Since the introduction of contactless payments, less and less people carry cash with them so it can be a hassle when supermarkets require a £1 coin for trolley use.

However, a mum-of-three has gone viral after showing her trick to unlock if you're short of a pound.
