The challenge

  • Every NFC/RFID reader brand ships its own software — no single, comprehensive solution
  • Validating UDID and matching it against databases manually and slowly
  • No mechanism for batch-writing hundreds of cards while guaranteeing no duplication
  • No strict validation of card data formats and quantity limits before writing

The solution

  • A unified Windows app supporting every NFC/RFID device automatically without special setup
  • A simple read/write UI with instant UDID validation during the operation
  • A batch mode writing 1 to 1000 cards with strict duplicate prevention
  • Strict validation of data format and quantity limits before every write
  • A complete log of every read and write with timestamps and the operating user
