Smart card has two rows of contacts (29) for connection to two groups of card reader contacts. The reader contacts have zones that extend perpendicularly downwards to contact with the two rows. The two groups of parallel contacts are offset relative to each other so that one set is shorter than the other to make contact respectively with one or other row of card contacts.
