Yes, all tools on NFCFYI are completely free with no account required. Tools run entirely in your browser (client-side JavaScript) and do not send your data to any server, ensuring privacy for sensitive information like encryption keys or NDEF records.
All tools are fully responsive and work on smartphones, tablets, and desktop browsers. Tools that interact with NFC hardware (like tag reading/writing) require a device with NFC support and a compatible browser (Chrome on Android for Web NFC API). Calculation and encoding tools work on any device.
Yes. NDEF records, memory calculations, and encoding outputs generated by our tools can be used freely in both personal and commercial projects. The tools are reference implementations and we recommend verifying critical outputs against the relevant NFC Forum or ISO specifications.
