The UK’s leading responsible gambling charity wants banks to do more to enable customers to prevent funding gambling activity via bank cards.

On Tuesday, the GambleAware charity issued a report titled A Blueprint for Bank Card Gambling Blockers, produced in cooperation with the University of Bristol. The report examines the growing trend of financial institutions empowering customers to prevent using a debit or credit card to access products carrying a gambling-related Merchant Category Code (MCC).

The report found that eight financial service firms covering around 60% of the UK’s total personal current accounts now offer blocking tools for certain products. That reportedly leaves around 28m accounts that lack access to these blocking tools.

This is unfortunate, because GambleAware’s report indicates that each of the roughly 500k Britons who have engaged blocking tools to date prevent an average of two to three gambling transactions each month. This amounts to between 390k and 585k total transactions blocked per month.
