The COLMI R02 smart ring does not support payments via Google Pay or Samsung Wallet based on available information. While COLMI offers a separate payment-enabled smart ring with NFC technology, the R02's documented features focus on health monitoring (heart rate, blood oxygen, sleep tracking) and activity recording without mentioning payment capabilities. For payment functionality, COLMI's product listings indicate a different model specifically designed for contactless transactions.

If you need confirmation beyond the provided specifications, I recommend contacting COLMI directly at service@colmi.com to verify compatibility with payment services.
