“Palm”-ing the Future: Palm Scanning Leads a New Wave of Mobile Payment

DEPTRUM

In the wave of digitalization, mobile payment keeps evolving; its convenience and security have won wide recognition, becoming an important part of smart living. With technological innovation, biometric technology is leading an innovative revolution in mobile payment, aiming to provide users with a more efficient and secure payment experience.

In recent years, the rise of face payment marked a major breakthrough in mobile payment — its intelligent and convenient experience made it a new choice for many users. Last year, palm-payment technology gradually came into public view, opening yet another new chapter of mobile payment.

Compared with other payment methods, palm payment offers higher initiative: no user device is needed and there are no behavioral constraints — simply extend your hand toward the palm device and payment is complete. DEPTRUM's palm-payment solution uses dual-factor verification of palm print and palm vein, employing multi-dimensional imaging to capture more comprehensive palm information, effectively reducing interference from differences in palm features and achieving more accurate identity and payment verification, further enhancing the security of palm payment.

Likewise, palm payment has advantages in privacy. Palm and palm-vein biometric information carries higher privacy than facial information and is hard to imitate, making it a better choice for mobile payment verification. Moreover, DEPTRUM's palm-payment solution has passed strict certification by the Third Research Institute of the Ministry of Public Security and the National Financial Technology Evaluation Center (NFEC), making the payment process even more reassuring.

In May 2023, WeChat palm devices officially entered service on the Beijing subway Daxing Airport Line, marking mobile payment's entry into the palm era. Meanwhile, WeChat palm-payment devices have been widely applied in transportation, sports, campus, retail, dining, office and shared-charging, successfully deployed at 7-Eleven convenience stores, Yingdong Gymnasium, Shenzhen University and many other scenarios, continuously promoting the adoption and expansion of palm-scanning technology.

Inside, the WeChat palm device carries DEPTRUM's dual-modal palm camera — the HandPass 100. Based on a dual-camera architecture and equipped with a high-performance ISP and AI module, combined with DEPTRUM's proprietary soft-core AE algorithm, it achieves rapid palm detection and closed-loop Palm AE, delivering high-quality palm-print and palm-vein images even in low-light and backlight scenarios.

As palm-payment technology matures and spreads, mobile payment is undergoing a transformative development. It not only brings users a more convenient and secure payment experience, but also drives the digital transformation of more scenarios. In the future, as palm-scanning technology extends into more application fields, palm payment is expected to become the first choice for offline payment, letting emerging technology continuously empower our lives.
