Tencent Cloud and Treeal launch palm-scanning payments in Brazil

Brazilian fintech Treeal has partnered with Tencent Cloud to bring the Chinese company’s PalmAI biometric payment system to Brazil. The service lets customers pay by scanning their palm, using vein pattern recognition instead of cards, phones, or cash.

Treeal will roll out the technology as an additional payment option for merchants, pitching it as a way to speed up checkout and cut reliance on physical credentials. The move places Brazil among the early markets outside China to test palm-based payments at scale, while raising the usual questions about how biometric data is stored, protected, and regulated.
