    2. 0.4. Why QR Codes Are Useful

A QR Code (Quick Response Code) is a two-dimensional barcode that stores data, often used in blockchain transactions to simplify address sharing and payments.

How QR Codes Work

QR codes encode information in a matrix of black and white squares that can be quickly scanned by devices like smartphones. In blockchain, QR codes are often used to share wallet addresses, enabling users to send and receive cryptocurrency easily. The code can store a variety of data, from links to transaction details.

Why QR Codes Are Useful

QR codes provide a fast and secure way to share information without manually entering long wallet addresses or transaction details. They’re especially useful in crypto payments, as they minimize human error and speed up transactions in real-world settings, from online stores to physical retail.
