AS3922-based NFC MicroSD features integrated antenna and active booster

austriamicrosystems has announced a solution, developed in cooperation with Infineon Technologies AG, that enables NFC (near field communication) data transfer on removable secure elements using a micro-antenna design. It will speed up the deployment and the acceptance of standalone NFC solutions based on ultra small form factors such as microSD. 

Working in close technical cooperation, austriamicrosystems and Infineon leveraged their respective expertise to design solutions that combine an Infineon security contactless microcontroller with austriamicrosystems’ AS3922 RFID front-end chip. Infineon’s secure microcontrollers are certified according to the Common Criteria and EMVCo international standards and answers to the requirements of NFC Mobile Payment. 

The AS3922, the result of the cooperation, supports an antenna booster technology to overcome the lack of reliability of the existing NFC microSD. Existing solutions only operate in a limited number of phones and over a very short distance. The NFC microSD solution is integrated with the micro-antenna included in the ultra small form factor. No other design approach currently on the market allows for reliable contactless payment fully enclosed within the microSD.
