TagTap

What it does

Write one tag, or a hundred.

TagTap turns a link, a Wi-Fi network or a contact card into something a phone opens with a tap — and keeps it so you never type it twice.

One link. Many tags.

Batch mode keeps the radio open between tags. Hold one, it writes and verifies, swap in the next. Twelve tags cost two taps instead of sixty. Put {n} in a link and each tag gets the next number — asset 1, asset 2, asset 3.

Turn a link into a tap.

Websites, Wi-Fi networks, contact cards, phone numbers, locations, app links and plain text. TagTap encodes them as proper NDEF records, so any phone understands them — not just this app.

Save and reuse.

Every tag you write lands in your library automatically — no save step. Tap the antenna on any row to write it again. Keep the ones you want forever; the rest roll off on their own.

Know your tags.

Deep scan reads the silicon: chip model, serial number, memory map, lock bits, password configuration and scan counter. It verifies the manufacturer's originality signature against the curve — and says genuine or not confirmed, never counterfeit.

Tags it reads

It tells you what it actually found.

An unlisted chip reports its vendor, family and rough size — and stops there. TagTap never invents a page layout it hasn't got data for, and an unreadable page is marked unreadable rather than filled with plausible zeroes.

Privacy

Nothing leaves your phone.

TagTap has no servers, no account and no analytics. The apps contain no networking code at all — your tags, templates and scan history live in the app's private storage and go nowhere else. The only connection either app makes is the one your phone's app store handles when you buy Pro.
