Free NFC tag writer
Write a URL to a blank NFC tag straight from your phone. No app, no signup. Chrome on Android writes the tag; the tag then works on any phone that reads NFC, iPhones included. Collecting Google reviews? Paste your Place ID and it writes the review link for you.
// this browser cannot write tags
Writing tags from a browser works in Chrome on Android. Open this page on an Android phone with NFC switched on and the writer appears here.
On an iPhone, Safari has no write API at all, so nothing on the web can write a tag there. Use a tag-writing app, or print the qrtag instead.

Four steps to a working tag.
- 01 Open this page in Chrome on an Android phone, with NFC switched on in system settings.
- 02 Paste the URL the tag should open, or switch to Google review and paste your Place ID.
- 03 Press Preview to open the destination in a new tab and check it is the right one.
- 04 Press Write to tag, hold a blank NTAG against the back of the phone, then tap it to test.
The writer puts one NDEF URL record on the tag and leaves it unlocked. Nothing is uploaded: the URL never leaves your phone.
Questions about NFC tags.
Can I write an NFC tag from my phone without an app?
Yes, in Chrome on Android. Chrome implements the Web NFC API, so this page writes the tag directly from the browser with no install. The tag then works with every phone that can read NFC, iPhones included. Reading a tag and writing one are different things.
Does this work on iPhone?
No. Safari has no Web NFC write API, so no website can write a tag on an iPhone. iPhones from the XS onwards read tags fine in the background. To write one, use an Android phone or a dedicated iOS tag-writing app, or print a qrtag instead.
Which NFC tags does this work with?
Any NDEF-formatted NTAG. NTAG213 holds 144 bytes of user memory, NTAG215 holds 504 and NTAG216 holds 888. A short link fits in all three with room to spare. Blank tags from any supplier work; the writer does not care who made them.
Can an NFC tag collect Google reviews?
Yes, and this tool builds the link for you. Switch the writer to Google review, paste your business's Google Place ID, and it writes search.google.com/local/writereview for that place. Put the tag on the counter and a customer taps their phone to land on the review form. Press Preview first to confirm the right business comes up.
Where do I find my Google Place ID?
Google publishes a Place ID finder: search your business name on it and copy the ID, which looks like ChIJN1t_tDeuEmsRUsoyG83frY4. This page never calls the Google Places API: you supply the ID and the review URL is assembled in your browser, so nothing about your business is sent anywhere.
Can I rewrite a tag I have already written?
Yes. Writing replaces whatever the tag held. This tool never locks a tag. The Web NFC call that makes a tag permanently read-only is not used here, because a wrong URL on a locked tag is a tag in the bin.
Is the tag readable if your service goes down?
A tag written with a plain URL is entirely self-contained and does not touch us at all. A tag written with a qrtags short link resolves through our edge, which is the trade you make for being able to re-point it after the tag is stuck to something.
Write a link you can still change.
This tool writes whatever URL you give it, and a bare URL on a tag is fixed for the life of the tag. Writing a qrtags short link instead keeps the tag exactly as it is while the destination behind it stays editable.
Re-point a tag that is already stuck down
A plain URL on a tag is permanent in practice: the tag is on a counter, a stand, a business card. Write a qrtags link instead and you change where it goes from the dashboard, without touching the tag.
One link, scan or tap
A qrtag and an NFC tag can point at the same link. Both triggers share the destination, so a menu change is one edit rather than two printings.
See the taps
Tags written with a qrtags link carry ?s=nfc, so a tap is counted as a tap rather than guessed at. Scans, taps and clicks read separately in analytics.
Route by device, place and time
The tag holds one link; what sits behind it is yours to change. Send iPhone taps to the App Store and everyone else to the web, split traffic between two destinations to see which one wins, and count what happens after the tap. None of it needs the tag rewritten.
Nobody quietly re-points your tag
A custom domain is DNS-verified before its links go live. So is every destination you point a link at: it is checked against an internal blocklist, DNS existence, Google Safe Browsing and the abuse.ch malware feed before it goes live, and rejected if any of them flags it.
Dynamic links with unlimited scans and years of analytics, on your own domain, from $15. A logged-in account writes tags from the link page itself.
