Secure NFC

Building the most effective and secure mobile solutions

ST is a recognized leader in secure NFC solutions for Mobile devices and has become a reference in the Android ecosystem. ST provides an exhaustive product offering, combining an NFC controller, an embedded Secure Element (eSE), and an embedded SIM (eSIM), either as a single chip (ST54 product line), or as discrete solutions (ST21NFC and ST33 product lines). Our secure NFC solutions support a vast range of secure mobile applications such as mobile payment, transit ticketing, access control, mobile ID, and digital car key. A white-label digital wallet, STPay-Mobile, is also offered to mobile OEMs to facilitate their “OEM-Pay” wallet deployment, including transit ticketing, access control, and payment.

Applications

Our secure NFC technologies are embedded in various devices such as smartphones, tablets, wearables, game consoles, laptops, and connected cars.
