QR Code Glossary

Learn terms, definitions, and technical features related to custom QR code generation, scannability check verification, and tracking analytics.

Dynamic QR Code

A QR code that redirects users to a target URL via a short redirection link. Unlike static QR codes, dynamic QR code targets can be edited after printing, and scan metrics can be tracked in real-time.

Static QR Code

A QR code that encodes the destination data directly into the matrix pattern. Once generated, static QR codes cannot be edited, and scans cannot be tracked or counted.

Error Correction Code (ECC)

A mathematical feature built into QR codes using Reed-Solomon algorithms that allows the code to be read correctly even if it is partially dirty, damaged, or covered by a custom logo.

Finder Pattern

The three distinct large squares located in the top-left, top-right, and bottom-left corners of a QR code. They help scanners detect the position, size, and angle of the QR code.
