A UK high street bank has become the first to enable customers to block gambling transactions.

Barclays mobile banking users can now block and control spending on gambling websites, retail betting shops, casinos and racetracks, as well as lottery tickets and scratch cards.

Developed with the Money Advice Trust and other advisors, the new service allows customers to also block transactions with groceries and supermarkets, restaurants, takeaways, pubs and bars, fuel and premium rate websites and phone lines.

The bank said the new feature is designed to give customers greater control over their money, as well as help protect them against fraud and scams.
