How Does Palm Pay Work—and What Happens When You Pay With Your Hands?

Biometric payment has entered a new era. With Palm Pay, users no longer need to carry cards, phones, or IDs—your palm becomes your secure identity. At BioWavePass, we’ve designed a hardware-agnostic platform to make Palm Pay truly scalable, privacy-compliant, and real-time ready.

So how exactly does Palm Pay work? What happens behind the scenes from a raised palm to a completed transaction?

This blog explains the core architecture of Palm Pay—optimized by BioWavePass technology and tested in real-world deployments across banks, government, and fintech.

Step 1: Biometric Registration Without Boundaries

Every Palm Pay journey starts with identity enrollment—binding the user’s palm to their digital profile. With BioWavePass devices, registration is fast, hygienic, and secured by AI-enhanced imaging.

Key Process:

• Palm + ID Binding
  Link national ID, phone number, or user account to a new Palm ID.

• RGB + IR Dual-Mode Capture
  We collect both surface palmprint and subcutaneous vein patterns.

• Feature String Extraction
  Our dual-modality AI engine generates four biometric markers:

  • RGB image
  • IR image
  • RGB feature string
  • IR feature string

• Secure Binding & Sync
  These are locally or remotely encrypted and stored under a unique biometric index.

Our devices require users to remove gloves to ensure clean IR & RGB imaging.

Step 2: Real-Time Matching at the Terminal

At checkout, subsidy points, or access control, users simply raise their hand.

Our terminal (e.g., BioWavePass500) instantly:

• Detects palm presence
• Captures new RGB + IR image streams
• Extracts fresh feature strings
• Matches against the database (cloud or local)

Only if all four factors match will Palm ID verification pass.

Algorithm Performance:

If either RGB or IR fails, the match will be denied. This ensures dual-liveness detection and zero tolerance for forgery.

Step 3: Payment Token Issuance

Once matched, the system generates a one-time payment token. This token acts as the user’s approval for the backend to proceed.

Token Payload Includes:

• BioPalmID: Anonymous user match key
• Terminal ID: Origin device identity
• Merchant Session: Transaction session code
• Nonce: Random anti-replay string
• Timestamp: Token validity (e.g. 30–60s)
• Signature: Encrypted hash of the above

No financial data or real identity leaves the device—only the secure token is transmitted.

Step 4: Payment Authorization

The token is sent to the connected payment platform, which may be:

• A bank payment gateway
• A government digital subsidy portal
• A private fintech cloud wallet

The backend verifies the token, checks permissions, and completes the transaction.

The result (success/failure) is then returned to the terminal in real time.

Palm Pay enables completely hands-free, cardless, password-free authentication while maintaining security.
