NFC vs QR code for Google reviews

TapStar guide · updated 2026-09-27

Short answer: NFC is faster and feels effortless — a customer taps their phone and the Google review form opens. QR codes work on every phone with a camera, including the minority where NFC is off or missing. The best Google review cards use both: an NFC chip inside and a printed QR code on the front, so every customer at your counter can leave a review, whatever phone they carry.

This guide goes deeper than any other page on the topic: how each technology works, which phones support what in India, speed, cost, durability, where each one fails, and how to set up a review card that works for everyone.

At a glance: NFC vs QR code for Google reviews

Times are typical, from a phone that's already unlocked; they vary by phone and connection.

How NFC works on a review card

NFC (Near Field Communication) is the same short-range radio technology used for contactless payments. A tiny chip inside the card stores one web link. It has no battery: when a phone comes within a few centimetres, the phone's own NFC field powers the chip for a split second and reads the link.

1. The customer holds the top of their iPhone, or the back of their Android phone, near the card.
2. A notification pops up with the link.
3. One tap on it, and Google's review form for your business opens.

On most Android phones the link opens straight away. On iPhone, a banner appears at the top of the screen that the customer taps. Either way, nothing needs installing.

How a QR code works on a review card

A QR code is a printed pattern that encodes the same kind of link. The customer opens their camera, points it at the code, and taps the link that appears. Every recent iPhone and Android phone reads QR codes in the built-in camera app; on some older Android phones customers use Google Lens instead.

Which phones support NFC in India?

• iPhone: every iPhone from the XR and XS (2018) onwards reads NFC tags without any app. The iPhone 7 and 8 need an app, so they should use the QR code.
• Android: most mid-range and premium phones from Samsung, Xiaomi, OnePlus, Vivo, Oppo, Realme, Motorola and Google have NFC, and so do many budget models from the last few years. Some very low-cost phones leave it out.
• NFC switched off: the most common failure. Some Android phones ship with NFC off, or users switch it off to save battery. It's usually under Settings → Connected devices (or Connections) → NFC.

That's exactly why a QR code on the same card matters: whoever can't tap, scans.

Speed: why every second counts for reviews

A happy customer at your counter has a short window of goodwill — the time it takes to pay and walk out. NFC fits comfortably inside it: tap, one confirmation, review form. QR adds opening the camera, lining up the code and tapping the link. It's only a few seconds, but in a queue, with a bag in one hand, those seconds are where reviews get lost. Our clients report customers finishing reviews in 3 to 5 seconds with a tap.

Where each one fails, and how to avoid it

NFC problems

• Wrong spot on the phone. iPhones read at the top edge; Android phones usually in the middle of the back. A small "tap here" icon on the card helps.
• Thick metal or magnetic phone cases. They can block NFC. Most normal cases are fine.
• Card on a metal counter. Metal right behind the chip can weaken the signal — use an acrylic stand or keep the card slightly raised.

QR problems

• Glare and low light. Shiny laminate under shop lights can stop the camera reading the code. Matte finishes scan better.
• Scratches and fading. A code on a busy counter wears over months. Keep the code large and protected.
• Too small. A QR code should be at least about 2 cm across for quick, reliable scans.

Durability and cost

A QR code costs nothing to print but wears out with handling. An NFC chip is sealed inside the card, has no battery, and keeps working even when the print is worn. Adding a chip costs a little more per card — which is why the best cards pair a protected chip with a printed QR backup. A TapStar card is a one-time purchase: ₹500 for the Google Review card, with no monthly fee and unlimited taps.

Where to place your review card

• At billing: the single best spot. Staff hand over the bill and point to the card.
• On tables or menus: restaurants fix cards to menus so guests tap while they wait.
• At reception: salons, clinics and hotels, where customers pay and book the next visit.
• On delivery bags: a QR sticker brings reviews from home deliveries.

Dynamic links: the part most cards get wrong

Many cheap cards write your Google review link directly onto the chip and into the QR code. If that link ever changes — you move, rebrand, or Google changes your listing — the card is useless. TapStar cards point to a short link we manage instead, so we can redirect it in minutes and the same card keeps working. It also lets us count taps and scans.

So which should you choose?

Don't choose — use both. An NFC chip gives most customers the one-second tap, and the QR code covers everyone else. That's how every TapStar card is made. If you want customers to reach your WhatsApp, Instagram and Maps too, and save your number, the All-in-One NFC business card does all of that from the same tap.

Is it allowed by Google?

Yes. Asking customers for reviews with a card or QR code is fine. What Google prohibits is offering discounts or gifts in exchange for reviews, and only asking customers you expect to be happy ("review gating"). A TapStar card simply opens Google's own review form — what the customer writes is up to them. See how to ask for a review without being pushy.
