NFC Review Cards vs QR Codes vs WhatsApp: Which Gets Tradespeople More Google Reviews?

You're standing in the van after finishing a job. The customer said they'd leave a review — they always say that. You know the drill: by tonight they'll have forgotten, and you'll have moved on to the next callout. So you start looking at your options. An NFC tap card you can hold up to their phone? A QR code on the back of your business card? Or just automating the whole thing with a WhatsApp message?

All three methods work. All three are better than hoping your customer remembers. But they solve the problem in completely different ways, at different price points, with different conversion rates. This guide breaks down each approach honestly — what works, what doesn't, and which suits the way tradespeople actually operate in 2026.

The core problem all three methods solve

Only about 10% of satisfied customers leave a Google review without being asked. But when you send them a direct link — whether by tap, scan, or message — that number jumps dramatically. The difference between asking and not asking is the difference between collecting one review per 10 jobs or three to four reviews per 10 jobs.

The reason isn't motivation. Your customers want to help. They just forget. They're making dinner, sorting the kids, answering work emails. The review they meant to write at 6pm is gone from their mind by 7pm. Every review collection method is really just a different way of reducing that friction — getting the Google review link in front of them at the right moment, in the right way.

So which method does that best?

NFC review cards: the tap-and-go approach

NFC (Near Field Communication) review cards and plates have become popular in the last couple of years. Companies like OneTap Review, TAPiTAG, ReviewsCard, and Footfall Reviews sell them for roughly £12 to £30 as a one-off purchase. You hold the card near a customer's phone, it opens your Google review page, and they can leave a review on the spot.

What works well: The interaction is novel and impressive — customers often comment on how professional it looks. There's an immediacy to it: the review page is open right now, on their phone, in their hand. For trades where you're face-to-face with the customer at job completion — a locksmith handing over new keys, a carpet cleaner (walkthrough on completion), oven cleaners (showing the customer the result) — it's a natural moment.

Where it falls short for tradespeople: This is the critical gap. Most tradespeople aren't standing face-to-face with the customer when the job ends. A roofer finishes while the homeowner is at work. A plumber fixes a leak and lets himself out. A heating engineer completes a boiler service and the customer is upstairs. The in-person tap moment simply doesn't happen for the majority of trade jobs.

Even when you are face-to-face, there's a psychological issue. Asking someone to tap your card right now while you're standing there creates pressure. Some customers feel put on the spot and leave a quick, generic review — "Good job, 5 stars" — rather than the detailed, specific review that actually builds trust with future customers. And there's no follow-up: if the customer declines or gets distracted, you've missed your window entirely.

Cost: £12–£30 one-off. No ongoing fees.

Typical conversion rate: Reported rates of 60–70% when the tap actually happens. But the tap only happens on a fraction of jobs, meaning your effective rate across all customers is significantly lower.

QR codes: free but passive

A QR code linked to your Google review page costs nothing to create. Print it on your business card, stick it on your van, add it to your invoices. Google even provides a direct review link you can turn into a QR code using any free generator.

What works well: It's free. It's easy to set up. You can put it everywhere — business cards, invoice footers, van signage, the sticker you leave on the boiler after servicing. It gives the customer a way to leave a review on their own time without any awkward face-to-face moment.

Where it falls short: QR codes are passive. They require the customer to notice the code, decide to scan it, pull out their phone, open the camera, and follow through. That's a lot of steps for someone who's just had their bathroom retiled and is thinking about where to put the towel rail. The code on your business card goes in a kitchen drawer. The sticker on the van is forgotten by the time they're indoors.

There's also no follow-up. If the customer doesn't scan the code today, there's no reminder tomorrow. No nudge a week later. The moment passes and the review never happens.

Cost: Free.

Typical conversion rate: Extremely variable, but generally low — estimated at 2–5% of customers who encounter the code. Most people see QR codes dozens of times a day and ignore nearly all of them.

Automated WhatsApp and SMS: the set-and-forget approach

This is where tools like TapReview sit. After you complete a job, the tool automatically sends your customer a WhatsApp message or SMS with a personalised Google review link. The message goes out at a timed interval — typically the same day or next day — when the customer is most satisfied with the work and most likely to respond.

What works well: It solves the two biggest problems tradespeople face with review collection — forgetting to ask and feeling awkward about asking. You don't have to remember to send anything, you don't have to stand there while they tap a card, and you don't have to hope they notice a QR code. The system handles it automatically.

WhatsApp is the natural channel. UK tradespeople already use it for customer communication — sending quotes, sharing photos, confirming appointment times. A review request via WhatsApp doesn't feel like marketing; it feels like a normal part of the conversation. SMS has a 98% open rate, and WhatsApp messages are read even faster.

The follow-up capability is the key differentiator. If the customer doesn't respond to the first message, a gentle reminder can go out a few days later. Research consistently shows that a single follow-up doubles the review rate. This is something neither NFC cards nor QR codes can do.

Where it falls short: It's not free. TapReview charges £9 per month. You also need the customer's phone number, though for tradespeople this is almost always available since you've been communicating with them throughout the job. And some customers — particularly elderly homeowners — may not use WhatsApp, though SMS covers that gap.

Cost: £9/month for TapReview. No contract, cancel anytime.

Typical conversion rate: 30–40% of customers sent a review request. With follow-ups, this can climb higher.

The numbers side by side

Here's what each method looks like across 100 completed jobs — a realistic volume for a busy tradesperson over two to three months.

NFC card: You're face-to-face with the customer at completion on roughly 40 of those 100 jobs. You remember to offer the tap on about 30 of those. At a 65% tap-to-review conversion rate, that's roughly 20 reviews. Cost: £15–£25 one-off.

QR code: All 100 customers receive your business card or see the code on your invoice. At a 3% conversion rate, that's roughly 3 reviews. Cost: free.

Automated WhatsApp/SMS: All 100 customers receive an automated review request. At a 35% conversion rate, that's roughly 35 reviews. Cost: £27 over three months (£9/month).

The gap between 3 reviews and 35 reviews is the gap between invisible on Google and showing up in the local three-pack. Research shows 10 reviews triggers an initial ranking boost, and businesses with 25 or more reviews earn significantly more than those with fewer. That's the difference automation makes.

Which method suits which trade?

Not every method works equally well for every trade. Here's a practical breakdown.

NFC cards work best for: Trades with consistent face-to-face handover moments. Locksmiths (handing over keys), carpet cleaners (walkthrough on completion), oven cleaners (showing the customer the result). If you're physically present, the customer is happy, and the job takes under an hour, the tap-and-go approach can supplement other methods well.

QR codes work best as: A supplement, not a primary strategy. On your van for neighbours who see your work. On invoices for the customer who opens the PDF a week later. On boiler stickers for the customer who sees it during their next service. They're passive lead generators — they won't collect many reviews, but the ones they collect cost nothing.

Automated WhatsApp/SMS works best for: Every trade, but especially those where you're not face-to-face at completion. Roofers, landscapers, decorators who finish while the customer is at work. Heating engineers who service boilers while the homeowner is upstairs. Builders on longer projects where there's no single "completion moment." And any tradesperson who's simply too busy to remember to ask — which, based on what we hear from tradespeople, is most of them.

Can you combine methods?

Absolutely — and it's often the smartest approach. Use an NFC card or QR code for in-person moments when you're physically with the customer. Set up automated WhatsApp/SMS as the safety net that catches everyone else. The NFC card captures the enthusiastic customer who's delighted right now. The automated message catches the customer who meant to leave a review but forgot.

The key is having at least one method that doesn't rely on you remembering. Because on a busy Tuesday when you've done three jobs, driven 60 miles, and still have to price up a kitchen refit, remembering to ask Mrs. Thompson in Solihull for a review is the thing that falls off the list. Every time.

Frequently asked questions

Are NFC review cards worth it for tradespeople?

NFC cards are worth it as a supplement if you regularly finish jobs face-to-face with customers. At £15 to £25 one-off, the cost is minimal. But they shouldn't be your only review collection method — most tradespeople aren't face-to-face at job completion on the majority of their jobs, and NFC offers no follow-up capability.

What's the best way to collect Google reviews as a tradesperson?

Automated review requests via WhatsApp or SMS produce the highest conversion rates at 30 to 40 percent, compared to roughly 0.4 to 2 percent for verbal asks and 2 to 5 percent for QR codes. The key is removing the need to remember — automation means every customer gets asked, every time.

How much does an NFC Google review card cost?

Most NFC review cards cost between £12 and £30 as a one-off purchase from companies like OneTap Review, TAPiTAG, and ReviewsCard. There are no ongoing fees. Some offer customisation or branded plates at higher prices.

Can I create a free QR code for Google reviews?

Yes. Find your Google review link through your Google Business Profile, then use any free QR code generator to create a scannable code. You can print it on business cards, invoices, or van stickers at no cost. The limitation is that QR codes are passive — there's no follow-up if the customer doesn't scan it.

Is it legal to send review requests via WhatsApp or SMS?

Yes, provided you follow UK regulations. Under PECR, you can send review requests to customers whose phone numbers you obtained during the service transaction, as long as the request relates to that service and includes an opt-out option. TapReview is designed to be fully compliant with UK messaging regulations.
