# Contactless Payments Platform

## What is a cashierless and contactless payment platform?

StreamPayments point-of-sale system is a cashier-less and contactless payment platform that uses palm recognition technology to identify customers and authorize transactions.

## How does it Work?

The digital palm-recognition payment option is being deployed separately from the "Just Walk Out" cashier-less, and contactless web3 payment platform. This eliminates the need for customers to carry cash or use physical credit cards, making the payment process more convenient and reducing the risk of spreading germs.

The "Stream" Device (POS system) then uses the Solana blockchain and AI technology to process and validate the transaction, which only takes a few seconds to complete.

## Biometric Authenticator

StreamPOS (point-of-sale) devices use palm recognition technology to identify customers and authorize blockchain-based transactions. Customers sign up at a kiosk or local store, where they insert their payment card and hover their palm over the point-of-sale system/cashier machine, which scans it and creates a customer ID and digital signature.&#x20;

### Cashless and contactless identity service

The StreamPayments device works by recording a user's palm "signature" – a unique identifier in humans. When the devices debuted, StreamPay algorithms build a map of your palm. Images are encrypted and sent to a "highly secure area" in the cloud where StreamPayments StreamPay™ creates your palm signature.

## Secured Signatures

To use the StreamPayments system, a customer has to sign up at a kiosk or locally. They simply insert their payment card and hover their palm over the StreamPayments device, so the device can scan it, make a customer id, and digital signature. StreamPay uses the Solana blockchain technology payment process, validation, and transaction take only a few seconds to handle.

It chose to use palms as biometric authenticators as they require an "intentional gesture" to trigger.&#x20;
