How Each Technology Actually Works
The underlying mechanics are straightforward, and understanding them makes the tradeoffs obvious.
QR codes
A QR code is a printed pattern. When a customer opens their phone camera and points it at the code, the phone reads the encoded URL and opens it automatically — no app required, no tapping, no contact. The scan happens from a distance of 15–30cm. Any smartphone with a camera can do this, which today means essentially every phone in use.
NFC (Near Field Communication)
NFC is a wireless communication standard built into many modern phones. An NFC-enabled card or tag contains a small chip. When a customer holds their phone within a centimetre or two of the tag, the chip transmits data directly to the phone — no camera involved. The experience is a tap rather than a scan.
NFC feels frictionless when it works. The problem is that it doesn't work for everyone.
The proportion of smartphones in current UK use with NFC enabled and accessible. QR works on 100% of phones with a camera — which is every modern smartphone.
The Compatibility Gap That Matters in Restaurants
NFC support on phones is well established on current flagship models, but the real-world picture in a busy restaurant is more complicated:
- Older iPhones (pre-2018) don't support background NFC reading. Customers with these phones can't tap an NFC card without downloading a separate app first.
- iPhones 2018–2020 support NFC but have it enabled only for Apple Pay by default. Accessing NFC review tags may require navigating into settings.
- Android phones support NFC broadly, but NFC must be switched on in settings. Many users have it off to save battery. The tap does nothing until they enable it — which most won't bother doing at a restaurant table.
- Budget Android devices, particularly common in the under-35 market, often omit NFC entirely to hit a lower price point.
Across a diverse dining room — families, older guests, tourists on foreign SIMs, customers with older handsets — a meaningful portion of your customers simply can't tap an NFC card. The exact figure varies, but estimates consistently put NFC availability at roughly 65–75% of smartphones in active use. That means one in four to one in three customers at your tables hits a dead end.
QR codes have no equivalent exclusion. Any phone with a camera — which is every phone sold in the last decade — can scan a QR code. For restaurants with a broad customer mix, this gap matters.
Real-World Usability: What Customers Actually Experience
Beyond compatibility, the day-to-day experience differs in ways that affect completion rates.
QR: visible, familiar, works from a distance
A QR card on a table is a known prompt. Customers understand what to do — point the camera, tap the link. The camera opens from any angle, from across the table, without the customer needing to pick up the card. Most people have scanned a QR code dozens of times in the last few years. There's no confusion about the mechanic.
NFC: requires physical contact and customer knowledge
NFC requires a deliberate tap — the customer needs to hold their phone within about a centimetre of the tag's exact location. This isn't difficult once a customer knows what they're doing, but it's not intuitive at a glance. Many customers who've never used NFC for anything other than contactless payments won't know they're supposed to tap the card specifically, or where on their phone to hold it. First-time users frequently fail on the first attempt, and in a restaurant context, a failed attempt usually ends the interaction.
NFC also creates an awkward physical moment — the customer picking up the card, finding the tag location, holding their phone against it while other people are watching. QR scanning happens naturally from a seated position with the card on the table.
Cost Comparison
Pricing differences between QR and NFC cards are significant at scale:
| Format | QR (Hamstars Pack10) | QR (basic print) | NFC cards | NFC devices/stands |
|---|---|---|---|---|
| Cost per unit | £1.49 | £1–3 | £3–8 | £10–25 |
| Works on all phones | ✓ Yes | ✓ Yes | ✗ ~70% | ✗ ~70% |
| Gamification / urgency | ✓ Yes | ✗ No | ✗ No | ✗ No |
| Setup time | 3 minutes | 3 minutes | 15–30 min | 30–60 min |
| Monthly fee | None | None | None | Usually none |
For a 10-table restaurant, equipping every table with QR cards costs £14.90 for a Hamstars pack. Equipping the same tables with NFC cards from a typical UK supplier runs £30–80. NFC devices or stands push that to £100–250. The replacement cost when cards get lost or worn follows the same ratio.
The Gamification Factor — What Neither Technology Does Alone
Here's the point that most technology comparisons miss: neither QR nor NFC, on its own, reliably drives customers to leave a review.
A card on a table is a passive prompt. Some customers will scan it. Most won't, unless something specific makes them act right now instead of later. "Later" means never — the moment a customer walks out the door, the probability of a review drops to near zero. Timing and urgency are what convert a scan opportunity into an actual review.
This is the role gamification plays. When a card tells a customer they're in the optimal window for leaving a review — while the experience is fresh, while they're still at the table — it creates a specific, time-bound reason to act. The psychology is the same as an in-restaurant upsell: context and timing turn passive awareness into action.
Participation rate when QR cards include gamification prompts (FOMO countdown + timing cue). A plain QR or NFC card in the same position typically achieves 60–70% with motivated customers, much less with casual diners.
Among current UK products, only Hamstars Pack10 includes this layer. Every other option — QR or NFC — puts a link in front of customers and leaves the conversion up to chance. QR with gamification produces consistently higher review volumes than NFC without it.
Where NFC Actually Has an Advantage
This isn't a one-sided argument. NFC has a genuine advantage in one area: perceived premium feel.
A tap interaction — phone to card, instant response — reads as more polished than scanning a printed square. In a high-end restaurant where the aesthetic of every table element matters, an NFC card or stand can feel more aligned with the environment than a QR code card.
If your venue serves a clientele that skews younger, tech-savvy, and all on current-generation smartphones, the compatibility gap narrows considerably. In that context, NFC's premium feel is a real differentiator.
For most independent UK restaurants — serving a mix of age groups, phone generations, and tech comfort levels — the compatibility argument outweighs the aesthetic one. You can't control which phones your customers carry. You can control whether your review prompt works for all of them.
The Verdict: Which Gets More Reviews?
QR + gamification wins on review volume. QR works for 100% of customers. Gamification converts passive card presence into active reviews. NFC wins on premium feel but excludes a portion of your customers and lacks the urgency layer that drives conversions. For maximising the number of Google reviews your restaurant collects per day, QR cards with built-in gamification are the correct choice.
The technology debate — QR or NFC — is the wrong framing. Both are delivery mechanisms. What converts customers into reviewers is timing, urgency, and removing every possible reason to put it off. QR handles the compatibility side. Gamification handles the psychology side. NFC handles neither better than QR, and costs more to deploy.
If you want premium aesthetics and your customer base is almost entirely on current-generation iPhones and Android flagships, NFC is a reasonable choice. If you want the most reviews per day from the broadest range of customers, QR with gamification is the answer.
