NXP gives an NFC credit card video demo

Capacitive touchscreen is a pattern identifier for NFC payments

AMSTERDAM: CHIPMAKER NXP showed off a near field communications (NFC) equipped smart card with a capacitive touchscreen for further authentication.

NXP's work on NFC has yet to fully pay off despite the firm boasting eight out of 10 smartphone vendors using its chips. One of the biggest fears, which the firm claims is not an issue, is the ability for payments to be made without the traditional layer of security that comes from a signature or a PIN being entered.

Arne Burghardt, a system engineer at NXP showed The INQUIRER a working prototype NFC smartphone with a capacitive touchscreen allowing the user to enter a pattern to authorise payments. The card doesn't have a power source and its thickness is nearly identical to that of existing credit cards.

Burghardt said the technology will be useful to reassure those who have fears that NFC could result in unauthorised payments. While he was able to show us a working demonstration, Burghardt told The INQUIRER that it will still be about two years before cards will be in the hands of users, but added that credit card makers will not have to substantially alter their processes to accommodate the touchscreen.

As can be seen from the video, the touchscreen resolution is fairly high, though Burghardt said it isn't quite enough for a full signature. He admitted that the demonstration unit did not support multitouch, however he said that capability can be added easily. µ
