Poland's PKO Bank Polski is upgrading six million customer Visa debit cards to contactless chip and PIN, according to local press reports.
The bank will begin replacing customer cards in June, with the entire upgrade project set to be completed by the end of 2011.
The Visa payWave technology will enable PKO customers to make low value payments at the point of sale by waving their cards against specially equipped readers, of which there are expected to be 20,000 of by the end of the year.
News of the move comes days after Intesa San Paulo in Italy committed to replacing its card base with MasterCard's PayPass contactless technology.
