# Crypto QR code

## Definition

A crypto QR code is a machine-readable visual encoding often used to transfer a wallet address, payment URI or connection information between devices.

## What it means in practice

A QR code can reduce typing mistakes but can also encode malicious or unexpected data.

## How this concept appears in Terenval Wallet

Terenval users should inspect the decoded address and network in the wallet rather than trusting a QR image by appearance alone.

**Important:** Treat QR codes from unsolicited messages or altered physical signs as untrusted until verified.
