NFC Batch Writer: TagDeploy

HappyAndroids Software Labs

About this app

Stop tapping tags one by one.

TagDeploy is a professional tool for batch NFC tag deployment. Write hundreds of tags from a single template, verify every write byte-for-byte, and hand your client an auditable report. Built for access-control installers, integrators and anyone who needs to write more than one tag at a time — think of it as the "ansible of NFC", not another single-tag writer.

BATCH WRITING, NOT ONE-TAG TOYS
Define a template once (URL, text or MIME record) with variables like {{index}}, {{uid}} or {{col:room}}. Load your data from a CSV file or enter it by hand, preview exactly what will be written to each tag, then run the batch. The screen stays on, progress is live, and you just tap tags one after another.

VERIFICATION YOU CAN TRUST
Every tag is written and then re-read straight from the chip to confirm the content is bit-identical before it counts as done — a genuine read-back, never a cached value. Failures are reported with clear, actionable messages — hold the tag longer, tag not writable, payload too large — never a bare "unknown error". Set a failure policy: keep going or stop on the first problem. Duplicate tags are detected and skipped automatically.

AUDIT REPORT
When the batch finishes, generate a self-contained, shareable HTML report with the result of every tag — ready to hand to your client as proof of the job.

WIDE TAG SUPPORT — INCLUDING MIFARE CLASSIC
NTAG213, NTAG215, NTAG216 and the MIFARE Ultralight family, plus NDEF writing to blank MIFARE Classic 1K/4K cards using the standard published keys (no key cracking, ever). A device check on first launch tells you exactly what your phone's NFC chipset supports before you buy a single tag.

OFFLINE AND PRIVATE BY DESIGN
No account, no server, no analytics, no ads. Everything — templates, data, results — stays on your device and never leaves it. NFC is the only permission the app asks for. Even the built-in feedback and support tool works offline: the optional diagnostic report includes your device model, NFC capabilities and recent event logs — never your tag UIDs or the data you write.
