What is NFC Technology and How Does TapTrust Use It?
NFC (near-field communication) is a wireless technology that lets your phone tap a card or tag to instantly connect with digital information. TapTrust by MRVL uses NFC to turn a single card into a smart profile: tap it, load your contact details and review prompt, and capture leads or Google reviews in one gesture.
How NFC Technology Works
NFC is a short-range wireless standard built into modern phones. When your device comes within a few centimetres of an NFC tag or card, it reads the data stored on that chip without needing internet or Bluetooth pairing. The tag itself is passive: it holds no battery and requires no power. Your phone does the work. In practice, you tap your phone on the card, a URL is triggered, and your browser loads instantly. No app download needed on the first tap. This makes NFC ideal for physical-to-digital handoffs: sharing contact details, linking to a website, or prompting an action like leaving a review.
NFC vs QR Codes and Other Tech
NFC and QR codes both bridge physical and digital worlds, but differ in key ways. QR codes require your camera app and a clear line of sight; NFC requires only a tap and works in pockets or wallets. NFC feels more premium and integrated. Bluetooth and Wi-Fi are longer-range technologies suited for pairing devices or streaming data over distance; NFC is designed for one-time reads at point-of-contact. For businesses handing out business cards, checking in customers, or collecting reviews at the point of sale, NFC offers a smoother user experience than scanning codes.
Real-World Uses of NFC
NFC tags are already embedded in hotel key cards, public-transport passes, and smartphones. In business, NFC is used for contactless payments (Apple Pay, Google Wallet), inventory tracking, and customer engagement. TapTrust focuses on the engagement use case: a freelancer, restaurant, salon, or estate agent hands you a card; you tap it on your phone; their smart profile loads with their contact details, social links, and a prompt to leave a Google review. The same card works as both a digital business card and a lead-capture tool. Each tap is logged with location and timestamp, giving the business real-time insights into who engaged.
Why Businesses Choose NFC Over Alternatives
Handing someone a physical card that works instantly when tapped feels natural and memorable. Unlike QR codes, which require users to open a camera app and hold their phone steady, NFC works in your pocket. Unlike SMS or email lists, which require opt-in friction, an NFC tap is frictionless and happens in the moment. For businesses that want verified Google reviews without chasing customers for feedback weeks later, TapTrust's NFC cards close the loop at the right moment: right after a transaction or service, when the customer is present and satisfied. The card also serves as a digital business card, so it pays for itself in utility.
Getting Started with NFC Cards
Modern iPhones (XS and later) and Android phones (NFC-enabled models) support NFC reads out of the box. No app is required for the first tap, though TapTrust has iOS and Android apps for team management, analytics, and custom branding. To use NFC as a business owner, you need an NFC card or tag and a smart profile. TapTrust provides both: the card is a physical, reusable NFC chip; the profile is your digital storefront built on TapTrust. When you tap the card, it links to your profile, which loads your contact card, social links, and a review prompt. Pro-tier users can reprogram their own NFC tags, so you're not locked into pre-printed cards.
TapTrust: NFC for Reviews and Lead Capture
TapTrust is an NFC customer-engagement platform designed for businesses that want both a smart digital business card and a Google review collection system. When a customer taps your TapTrust NFC card, they see your contact details, social profiles, and a one-tap prompt to leave a Google review on your business. All feedback goes through Google's verification system, so reviews are authentic. TapTrust also captures lead data: email, phone, or notes from each tap. Real-time tap analytics show which customers engaged, when, and where. Estate agents, mortgage brokers, restaurants, salons, gyms, and freelancers use TapTrust to build credibility, collect verified reviews, and follow up with warm leads. The free tier gets you started with one profile card and up to 3 reviews per month. Pro and Business+ tiers unlock team management, CRM export, and NFC tag writing.

Frequently asked questions
Do I need special hardware to use NFC?
No. Any iPhone XS or later, or NFC-enabled Android phone, reads NFC cards natively. No special app or hardware is needed for your customers to tap your card.
Can I reprogram an NFC card?
Yes, if you're on TapTrust Pro tier or higher. Pro-tier users can rewrite NFC tags themselves, so you can update the profile link or change which action the card triggers without buying new cards.
Is NFC secure?
NFC is read-only by default; data is not encrypted in transit, but TapTrust cards link to HTTPS profiles, so the connection is secure once your phone loads the profile URL.
How far does NFC work?
Typically 10 centimetres or less. Your phone must be held close to the card for the tap to register.
Can I use TapTrust NFC cards for things other than reviews?
Yes. Your card works as a digital business card; tapping it loads your contact details, social links, and any custom profile you build. You can also use it to direct people to a website, PDF, or form. Reviews are optional.
What happens when a customer taps my TapTrust card?
Your smart profile loads instantly in their browser. They see your contact card, social links, and (if enabled) a one-tap prompt to leave a Google review. All taps are logged in your TapTrust dashboard with location and time.
