@schie/epc

A modern, type-safe TypeScript library for generating and parsing EPC (Electronic Product Code) identifiers used in UHF RFID tags.

• 🔍 Parsing - Decode EPC hex into structured data
• 🛡️ Type Safe - Full TypeScript support with comprehensive types
• 📦 Zero Dependencies - Lightweight and fast
• 🧪 Ready for Testing - Built for easy unit test coverage
