NatWest has introduced a new gambling block for customers.
The bank has added the feature for debit card holders, giving customers who may suffer harm a 48-hour cooling-off period before they can make payments.
The new introduction aims to help customers with gambling addictions to take control of their spending.
These customers will now have to wait 48 hours before they can make gambling-related payments, during which time any attempted transactions will be automatically declined.
The block remains in place unless a customer chooses to remove it, in which case it can be disabled after 48 hours.
NatWest customers can access the gambling control in their mobile banking app via a "manage my card" feature.
David Lindberg, CEO of retail banking at NatWest, said: "The introduction of a gambling block for debit card customers will help us to equip problem gamblers across the UK with more tools to support their recovery.
"Problem gambling and financial hardship go hand in hand and through our work with GamCare, we have offered an increasing amount of help to those customers who need it most through our trained specialists and donating branch space for treatment therapy to reduce traditional barriers to access."
A similar scheme is already in place at Barclays which offers a 72-hour wait.
