A CHARITY key ring which unlocks supermarket trolleys is a hit in Huddersfield.

The new "pound for life coin-key ring" is designed to put an end to frustrated fumbling in trouser pockets or purses for a £1 coin.

The substitute pound coin token has been created for use in supermarket trolleys or gym lockers and is the same shape and weight as an actual coin.

For each £1.50 coin-key ring sold about £1 goes to the Child Victims Support charity.

The registered charity raises money to care for child victims of sexual and physical abuse and victimisation, as well as children who have lost limbs or are paralysed as a result of road accidents.

Mr Paul Coulson, manager at Sainsbury's Market Street branch in Huddersfield, said: "This is an excellent idea and they seem to be selling well. It can be quite frustrating to have to search for a pound every time you shop.

"Lots of our customers, especially the older ones, have said they find it handy to have the coin-key attached to their keys or purse.

"The customer simply unclips the token and pops it in their trolley. When they have finished shopping they can retrieve the token and put it back on the key ring," said Mr Coulson.

The coin-key rings can be bought from customer service areas at the Market Street store and Sainsbury's Shore Head shop.
