Abstract
A wearable payment device, such as a finger ring worn by a user, communicates payment data via an antenna to a payment reader that uses the payment data in order to request a payment transaction. The wearable payment device can tune the antenna to enhance performance of the antenna. The wearable payment device can measure a characteristic of the antenna and perform an assessment of the performance of the antenna based on the measured characteristic. The antenna can be tuned, such as by changing the impedance of the antenna, based on the assessed performance of the antenna.
