Shares in Ingenico SA have been taking a tumble on the Paris Bourse, but the company says that whatever the reason for the slide, it’s nothing to do with its medium-term prospects: as to those, it says that it is moving into Smart Cards with a device that uses a similar technology to the one pioneered by GEC Plc here, that is to say one that uses induction rather than fragile metal contacts to transfer the information stored inside; it does not see the planned cards competing with the ones made by Bull and others in the banking and financial world, rather it expects them to find widespread use in access control and other security applications, and points out that they can be securely erased and re-recorded, and can be turned out in billions where the cards currently in use are only produced in hundreds of millions; as it also plans to diversify into the field of archiving on optical disk in partnership with companies of the very first rank in October, it reckons that investors will have to look somewhere else to find reasons for the slump in its share price.
