Palm Biometrics Surge Ahead in Healthcare, Payments, and Blockchain Despite Big Tech Pullback

Introduction: A New Era for

are making a strong comeback. Even after a major setback from Amazon, this touchless tech is gaining speed in key areas like healthcare, payments, and blockchain. Why? It offers top security, speed, and ease. In this post, we dive into real-world uses and why could change how we verify identity in crypto and beyond.

Amazon Steps Back, But Push Forward

Amazon recently announced it will end its Amazon One system in retail stores. Users can still use it until June 3 in some spots. This move ties into Amazon closing 72 Amazon Go and Fresh stores in the US. The company now focuses on Whole Foods and delivery.

But here’s the good news: Amazon keeps for healthcare check-ins. And others are stepping up. Big retreats by US firms don’t stop global growth. shine with low error rates and fast scans, perfect for secure needs.

Transform Healthcare in Hong Kong

In Hong Kong, Tencent teamed up with Bupa to launch in 20 clinics. Called “Express Check-in,” it uses kiosks with Tencent’s PalmAI tech. Key spots in Central, Tsim Sha Tsui, and Admiralty have scanners. Others use QR codes as backup.

PalmAI mixes palm print and palm vein scans for dual security. Patients just hover their hand—no cards or staff needed. It cuts wait times, boosts hygiene, and links to the Blua Health app.

“By leveraging Tencent’s advanced PalmAI technology… we are enabling a secure, contactless, and truly frictionless check-in experience,” says Steven Choi, general manager of Tencent Cloud Hong Kong and Macau.

Yvonne Leung, Bupa’s chief customer officer, adds that patients access care without papers. This is one of the first big rolls in Asian healthcare.

Brazil Embraces for Fast Payments

Next stop: Brazil. Tencent partners with fintech Treeal to bring PalmAI to business payments. Brazil loves new tech, and this fits right in.

PalmAI boasts a false acceptance rate under 1 in a billion. False rejection? Just 0.01% or 1 in 100,000. Scans take only 300 milliseconds. Super fast and safe.

“Brazilians are known for early adoption… palm biometrics could become mainstream within five years,” says Treeal CEO João Santos.

Eric Li from Tencent Cloud sees it expanding to smart access and city mobility. could redefine secure transactions in fintech.

Enter Blockchain: Pi Network’s Big Test

The real game-changer? Blockchain and crypto. Pi Network, a massive Web3 project, just added in beta. It boosts their Mainnet and KYC for millions of users.

Pi has 16 million users on Mainnet—one of the largest identity-verified blockchain networks. Nearly 2.5 million blocked users now migrated, with 700,000 more coming. offer an alternative to face scans for liveness checks, account recovery, password resets, and 2FA.

“Pioneers who already require multiple face liveness checks… palm prints could potentially be used as part of broader authentication flows,” says Pi Network.

This beta rolls out soon to select users for testing. In crypto, where KYC fights fraud, add robust, private verification. Imagine wallet logins or NFT trades secured by your palm—no passwords needed.

Why Beat Other Options

• High Accuracy: Dual palm print + vein tech beats fingerprints in fakes.
• Speed: Under 1 second verifies you.
• Hygiene: No touch, ideal post-COVID.
• Spoof-Proof: Vein patterns are hidden inside skin.
• Versatile: Works for healthcare, payments, and decentralized ID in blockchain.

Compared to face ID, palms are harder to fake and less privacy-invasive—no photos stored.

The Blockchain Angle: Secure ID for Web3

In crypto, identity is key. Scams, hacks, and regs demand strong KYC. Pi Network shows how fit blockchain. With 16M verified users, it’s scalable.

Future? Think DeFi logins, DAO voting, or cross-chain bridges using palm scans. Projects like Pi pioneer this, blending biometrics with decentralized trust. No central database—your palm is your key.

As Web3 grows, could solve Sybil attacks and boost adoption. Pair with zero-knowledge proofs for privacy.

Challenges and Road Ahead

Not all smooth. Privacy worries exist—data breaches scare users. Regs vary by country. Amazon’s exit shows retail hurdles like adoption costs.

Yet, success in HK, Brazil, and Pi proves demand. Experts predict mainstream in 5 years. For blockchain, it’s earlier—crypto moves fast.

Conclusion: Are Here to Stay

Amazon’s pullback is a blip. gain ground in healthcare, payments, and blockchain. From Bupa clinics to Treeal payments and Pi’s 16M network, real deployments show promise.

Stay tuned— this tech could secure your next crypto trade or doctor visit. What do you think? Will replace passwords in Web3?
