## Description

Professional GS1 and UDI scanning with field parsing, Hex debugging, batch review, and local data control.

GS1 Barcode UDI Field Check is a professional GS1 and UDI barcode parsing and field review tool for supply chain teams, warehouse operators, medical device workflows, quality checks, and barcode engineers.

It does more than read a code. The app parses GS1 Application Identifiers, shows fields such as GTIN, lot, expiry date, and serial number, and helps inspect UDI data, FNC1 separators, Hex/ASCII payloads, and batch scan records.

Key Features:
- Parse GS1 Application Identifiers
- Review GTIN, lot, expiry, and serial fields
- Check common UDI data elements
- Inspect FNC1, GS, Hex, and ASCII data
- Scan and review batches continuously
- Export records as CSV or JSON
- Keep scan data local without cloud dependency

Use Cases:
- Warehouse and inventory checks
- Medical device UDI review
- GS1 DataMatrix debugging
- Supply chain and logistics verification
- Barcode printing and encoding troubleshooting

Note: This app is designed for local scanning, parsing, and field checks. It is not an official GS1 app and does not provide legal compliance certification.
