NFC is a short-range wireless technology built into most modern smartphones. When a phone is tapped against an NFC chip embedded in a card, sticker, or stand, it reads the data stored on the chip — typically a link to a Google Business Profile (opens in new tab) review page — and opens it automatically, without needing a camera or scanner app.
How an NFC Tap Actually Works, Step by Step
An NFC chip is a tiny passive antenna embedded in a card, sticker, or stand — it carries no battery of its own. When a phone with NFC enabled comes within a few centimetres, the phone’s own NFC radio powers the chip briefly, reads whatever data is stored on it (almost always a single URL), and the phone’s operating system opens that link automatically, no app or camera required.
This is the same underlying technology behind contactless UPI and card payments in India, which is part of why NFC feels instantly familiar to most smartphone users even before they’ve used it for anything else.
Where NFC Shows Up in a Local Business
- An NFC review stand at the billing counter that opens the Google review page on tap
- An NFC-embedded business card that opens a digital business card or contact-save prompt
- An NFC table tag that opens a digital menu without needing to line up a camera
- An NFC sticker on a door or window that opens a booking page or WhatsApp chat
NFC vs QR Code, in Practice
NFC and QR codes solve the same basic problem — getting someone from a physical moment to a specific link — but they behave differently in the real world. NFC is faster and feels more premium (a tap versus lining up a camera), but it only works on NFC-enabled phones with the feature turned on, and it’s invisible until someone knows to tap it. A QR code is universally scannable and visibly signals "there’s something here to scan," which is why most businesses that use NFC still keep a QR code as a visible backup on the same card or stand.
People also ask
Do all phones support NFC?
Nearly all smartphones sold in India since 2018-2019 support NFC, including most mid-range Android devices and all iPhones from the 7 onward. A small number of budget devices still lack it.
Is NFC safe to use?
Yes — NFC only reads data within a few centimetres and cannot be triggered from a distance, making it a low-risk way to share a link compared to, say, a public Wi-Fi connection.
