German-facing online casinos are losing their ability to access Visa or Mastercard services as the government puts the squeeze on unauthorized gambling transactions.

On Wednesday, German media outlet NDR reported that Visa had instructed its partner banks not to process online casino deposits or withdrawals using its credit cards. A Visa spokesperson said its retail banking partners were recently contacted “to ensure that only legal, properly licensed transactions are processed.”

In recent weeks, online gambling affiliate forums had been filling up with complaints that this or that online casino was no longer accepting Visa or Mastercard payments for their German customers. The casinos generally stated that it was either suspend these German payments or lose Visa or Mastercard access in all markets.

That said, the situation isn’t entirely uniform. NDR found that, while local betting operator Tipico had removed all mention of Visa from its platform, GVC Holdings’ Bwin brand was telling German customers that they could continue using Visa for sports betting only.
