An Post expects customers to be able to use its prepaid Money Currency cards from today.
Holders of the cards had been unable to use them since last week when British authorities shut down the scandal-hit German payments company Wirecard, which is the issuer of the An Post Money Currency card.
Wirecard was told to halt its business after news that €1.9bn was missing from its company accounts.
While holders of the An Post cards were affected, so too were shoppers who held gift cards for Mahon Point Shopping Centre in Cork.
Shoppers were shocked to discover their gift cards, which were also issued by Wirecard, were not being accepted.
Shoppers had been unable to use the gift cards since last Friday. However, a spokesperson for Mahon Point Shopping Centre confirmed its gift card service has now resumed.
An Post said it expects its currency card will be operational again from later today.
