Customers urged to cope with frustrations of extra checks in interests of safety.
Bank customers are being asked for more forms of identification as part of a global crackdown on money laundering and terrorism.
The Bankers Association said customers will find the new checks frustrating and is urging them to remember why they're in place.
From the end of next month, the Anti-Money Laundering and Countering Financing of Terrorism Act 2009 is implemented and all banks will be obliged to check customers' identity and in some cases their account activity. Some banks have been implementing the changes early.
The enhanced regime applies to all banks, and other financial institutions, and builds on existing customer identification processes.
