## What is QR?

QR-Code Master is a powerful scanner and generator for QR codes, barcodes, and 2D codes.

SCAN ANY CODE
Point your camera at any QR code, barcode, or 2D code and get instant results. Supports QR Code, Aztec, Data Matrix, PDF-417, EAN-13, EAN-8, UPC-A, Code 128, Code 39, and Codabar. Pinch to zoom for small or distant codes.

DEEP ANALYSIS
See the full technical details of every code you scan: QR version, error correction level, mask pattern, encoding segments, and more. View color-coded visualizations that highlight finder patterns, alignment patterns, and timing patterns.

GENERATE CODES
Create QR codes, Aztec codes, Data Matrix, PDF-417, and all supported 1D barcode formats. Live preview updates as you type. Fine-tune QR parameters including error correction level, version, mask pattern, and encoding mode.

BATCH SCANNING
Switch to batch mode to scan multiple codes in rapid succession. All scanned items are saved together for easy review.

SCANNER FILTERS
Only scan the code types you need. Enable the scanner filter and select which formats to accept.

HISTORY
Every scan is saved with full details. Review, search, and re-open any previously scanned code.
