Alipay’s biometric PL1 scanner uses vein and palm-print data for processing payments, raising security concerns over the storage and use of permanent biometric data.

Alipay, the financial arm of Alibaba, has introduced a new palm-based biometric terminal, dubbed the PL1, which enables individuals to make purchases simply by presenting their hand – no phone, card, or PIN required. Positioned as a faster, touch-free alternative for payment, this system reflects a growing industry shift toward frictionless biometric transactions.

At the core of the PL1 is a dual-mode recognition system that combines surface palm print detection with internal vein mapping. This multi-layered authentication relies on deeply unique biological signatures that are significantly harder to replicate than more common methods like fingerprints or facial scans. Alipay reports that the device maintains a false acceptance rate of less than one in a million, suggesting a substantial improvement in resisting identity spoofing.

Enrollment is designed to be quick: users hover their palm over the sensor and link their account through a QR code. Once registered, purchases are completed in around two seconds without physical interaction. During early trials in Hangzhou, this system reportedly accelerated checkout lines and contributed to more hygienic point-of-sale environments.

The PL1 arrives at a time of rapid expansion in the biometric payments sector. Forecasts estimate that more than 3 billion people will use biometrics for transactions by 2026, with total payments surpassing $5 trillion. Major players are already onboard: Amazon has integrated palm authentication across U.S. retail and healthcare facilities, while JP Morgan is gearing up for a national deployment in the same year.

Alipay envisions the PL1’s use extending well beyond checkout counters. It is exploring applications in public transit, controlled access facilities, and healthcare check-ins, reflecting a broader trend toward embedding biometric systems in daily infrastructure. However, while domestic deployment benefits from favorable policy conditions, international expansion may be constrained by differing legal standards, particularly in jurisdictions that enforce stringent rules on biometric data usage and consent.

Despite the technological advancements and convenience the PL1 offers, privacy remains a major point of contention. Unlike passwords or cards that can be reset or replaced, biometric data is immutable. If compromised, individuals cannot simply “change” their palm patterns or vein structures. This permanence heightens the stakes of any potential data breach and raises long-term concerns about identity theft and surveillance.

Alipay’s approach, storing encrypted biometric templates locally on devices and restricting data flow within national border, does address certain regulatory demands, especially within China, but the broader implications of biometrics are likely to be a growing privacy and surveillance concern in the coming years.
