HSBC Holdings-sponsored Mondex card is heading for a clash with the industry-wide smart card standard, being developed by Europay, Mastercard and Visa (EMV).
The three major card organisations, EMV, have announced that further global specification on the smart card system will be released by mid-June.
The step will move the industry closer to a worldwide framework for the use of smart cards.
'The release of the card and terminal specifications will represent a stable base upon which the financial services industry can begin to develop chip card applications that are capable of functioning across borders and systems,' EMV said.
Banks around the world have taken a cautious stand on smart cards, hoping to wait until a global framework comes out before making an investment.
But Midland Bank, British Telecom and NatWest have embarked on the Mondex project, a smart card project that has its own chip-card technology.
