How an NFC Google review sign works
22 September 2026 · 4 min read
An NFC review sign is a small stand or card with a chip inside that holds one thing: the web address of your Google review form. A customer holds their phone near it and that page opens. No app, no typing, no searching for your business.
What is actually stored on the chip
The chip is an NTAG215, the same kind used in transit cards and hotel keys. It holds a few hundred bytes, and we write one URL to it: the direct link to your Google Business Profile review form.
That link is built from your Place ID, the identifier Google gives every listed business. It is the same address you would get by clicking "Ask for reviews" in your Business Profile, so the page your customer sees is the official one.
What happens in the three seconds after a tap
The phone powers the chip through the antenna, reads the URL, and shows a notification. Tapping it opens the review form in the browser the customer already uses, signed into the Google account they already have.
- iPhone XS and later read tags in the background with the screen on — nothing to open first
- iPhone 7 to XR need the NFC widget or the camera, which is why every stand can be ordered with a printed QR code too
- Android phones have read tags in the background since Android 4.4
Why it collects more reviews than asking out loud
Asking a happy customer for a review usually costs them six steps: unlock, open Maps, search the business, pick the right listing, scroll, tap review. Most people abandon somewhere in the middle, and the ones who try at home have forgotten by the evening.
A tap removes five of those steps and happens while the customer is still standing in front of you, which is when goodwill is highest.
Questions, answered
- Does the customer need an app?
- No. Reading NFC tags is built into every modern iPhone and Android phone, and the review page opens in their normal browser.
- What if their phone is old?
- Order the stand as “Tap + QR code” and it carries a printed QR code as well, at the same price, which works on any phone with a camera.
