The app is free and receives frequent updates to expand compatibility with more tag models and improve usability. It operates on the standard NFC frequency (13.56 MHz), enabling reliable interaction with common tag types.

Key capabilities

• Read and decode tag contents and present useful next-step actions based on what’s found.
• Write a variety of data types to tags, with safeguards to prevent overfilling tag memory.
• Display in-depth technical attributes such as tag family, supported protocol, and available storage.

Types of data you can store

How it helps during problems

• Warns you before attempting to write data that exceeds a tag’s capacity.
• Provides troubleshooting hints when reads or writes fail, making diagnostics straightforward.
• Suggests sensible actions (for example, opening a URL or adding a contact) based on detected records.

Maintenance and updates

Frequent releases address compatibility with an expanding range of NFC chips and tag formats, refine user-facing flows, and patch issues reported by users, helping ensure the app remains useful over time.
