RFID chip makes analogue watches smart

The RFID chip designed at Infineon's contactless competence centre in Graz, Austria is used in the patented STISS (Swiss Technology Inside Smart Sapphire) sapphire crystal to provide secure payment transactions by radio frequency within 200 milliseconds.

More and more people around the world are paying with contactless because it's easy, fast and hygienic. Especially in the wake of the Corona pandemic, the acceptance and spread of the technology has accelerated significantly.

"A fast and robust connection from the watch to the reader at the checkout is crucial for customer acceptance," said Alex Kalbermatten, CEO of Winwatch. "Infineon surpasses all other solutions currently available on the market in terms of wireless quality. For example, by integrating the contactless chip we were able to develop a sapphire crystal that turns every watch - from mechanical heirlooms to metal sports watches - into a contactless payment device. And all of this without a battery."

"Whether with a classic card, a fashion accessory such as a ring or smart wearables – chip innovations from Infineon combine the real and the digital world and enable simple, secured and hygienic payment transactions," says Björn Scharfen, Head of the product line Payment & Ticketing Solutions at Infineon. With our security and contactless expertise as well as energy-efficient chip design, we play a leading role in this growth market".
