Infineon Provides Tiny Chips for Contactless Payment
The Swiss company Winwatch has merged tiny security chips from Infineon Technologies almost invisibly into its patented sapphire crystal STISS. The chip enables fast and secured payment transactions by radio frequency within milliseconds.
“A fast and robust connection from the watch to the reader at the checkout is crucial for customer acceptance,” says 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”.
Communication between the card or wearable and the reader is based on NFC (Near Field Communication) technology. At a distance of two to ten centimeters, the chip uses only the energy field of the reader to calculate, encrypt and transmit the data.
