Sber's smart ring now functions as a payment instrument. Payment is made via the "Vzhukh" technology on biometric terminals. To confirm a purchase, hold your hand parallel to the floor and tap the tag twice.

Payment is available throughout Russia at Sber and partner bank biometric terminals that support "Vzhukh". To activate the function, you need to link any Sber account to the ring's application.

The technology uses the Bluetooth Low Energy protocol: no internet is required, and encryption protects data from forgery and interception. This is the first Russian smart ring with both payment and health tracking capabilities.

The built-in GigaChat neural network analyzes body data, forms individual trends, and provides recommendations. If indicators change, the owner can choose a doctor and undergo diagnostics through SberZdorovye. The ring transforms from a fitness accessory into a full-fledged payment and medical instrument, expanding scenarios for wearable electronics.
