Swiss company Winwatch has integrated tiny security chips from Infineon Technologies AG almost invisibly into its patented sapphire crystal STISS® for this purpose. The chip enables fast and secured contactless payment transactions by radio frequency within milliseconds.
More and more people around the world are paying 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. In addition to ATM or credit cards, so-called wearables are also in high demand.
"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.
The most widely used contactless payment method is still the credit or debit card. According to ABI, already two thirds of all cards used today are contactless. Their share is expected to grow to more than 80 percent by 2025. The market researchers estimate another 1.9 billion contactless cards to be shipped in 2020 worldwide. The demand for wearables with a payment function is also growing continuously. According to a study more than 75 percent of all Mastercard transactions in Europe are now contactless. Payment transactions with smartphones and wearables have doubled within a year from seven to 14 percent.
