Three million people with an ICS credit card will have to go through a new identity check as part of ABN Amro’s efforts to get compliance with anti-money laundering rules up to scratch.

International Card Services, which is part of ABN Amro, is asking all clients to reconfirm their identities and while an online procedure is being prepared, this currently has to be done in person, the Volkskrant said on Friday.

ICS is contacting clients by mail and letter and is setting up mobile bases to make the checks as easy as possible. The entire process is expected to take several years to complete.

ABN Amro said in August at the presentation of its half-yearly figures that it had been ordered by the central bank to look again at all its retail clients.

And last month the Dutch public prosecution department launched a criminal investigation into possible money laundering at ABN Amro. The probe follows a report made by the Dutch central bank and ABN Amro is suspected of falling to report suspicious transactions over a longer period.

Earlier this year ING was fined €775m for being lax in its approach to money laundering.
