What is an NFC Card and How Does It Work?
An NFC card is a contactless smart chip embedded in a physical card that transmits data when someone taps it with their smartphone. TapTrust by MRVL uses NFC cards to instantly load a smart profile, capture leads, and collect Google reviews in a single tap.
Definition and Basic Function
NFC stands for Near Field Communication. An NFC card is a physical object, usually credit-card sized, that contains a passive microchip. When a smartphone with NFC enabled comes within a few centimetres of the card and taps it, the chip transmits a pre-programmed URL or data payload to the phone. Unlike QR codes, NFC requires no camera angle and no light. The user simply taps and the action happens. TapTrust encodes each NFC card with a link to your smart profile. When someone taps your card, their phone instantly opens your contact details, business information, and a prompt to leave a Google review. No app download needed on their end.
How NFC Cards Differ from QR Codes
Both NFC and QR codes transmit data, but they work differently. QR codes require the user to open their camera app, frame the code, and wait for recognition. NFC cards need only a tap and work in the dark, in wet conditions, and at angles. NFC feels more like a natural handshake than a scan. For business networking and customer engagement, NFC cards feel more intentional and premium. TapTrust cards work best in face-to-face settings where you hand someone your card and they tap it immediately. The tap triggers an instant connection and lead capture, making the interaction measurable and trackable in real time.
Real-World Uses for NFC Cards
NFC cards serve many industries. Estate agents use them to send property details and lead forms. Mortgage brokers tap prospects into a contact capture flow. Restaurants, salons, gyms, and retailers use NFC cards as digital menus, booking prompts, or loyalty triggers. Freelancers and creatives use NFC cards as smart business cards that double as portfolio links. The common thread: every tap is logged with location and timestamp, creating a real-time record of who engaged with your card and when. TapTrust adds a review layer. Each tap includes an option for the recipient to leave a Google review, turning a business card into a review-collection tool that builds your verified Google rating.
TapTrust: NFC Cards Built for Reviews and Leads
TapTrust is an NFC customer-engagement platform that turns your NFC card into a dual-purpose tool. When someone taps your card, they see your smart profile (contact info, links, image), a lead capture form, and a prompt to leave a Google review. All in one tap. You get real-time analytics showing where and when each tap happened, who filled out the lead form, and which taps converted to reviews. TapTrust also supports NFC tag writing on Pro tier and above, meaning you can re-program your own NFC chips instead of relying on pre-printed cards. The Free plan includes 3 smart profiles and basic tap tracking. Pro and Business plans add more profiles, team management, CRM export, and custom domains.
Why Choose TapTrust Over a Generic NFC Card
Generic NFC cards are passive tools that link to a single URL. TapTrust builds intelligence on top of the tap. Every interaction feeds into your lead capture form and Google review system. You see exactly who tapped your card, where they tapped it, and whether they left a review. The card itself becomes a marketing asset with measurable ROI. Plus tier unlocks streak bonuses and monthly reward credits to encourage repeat taps. Business+ tier adds CRM integration, team collaboration, and a custom domain so your smart profile feels like part of your brand. Enterprise tier includes white-label options for agencies and resellers who want to offer NFC cards under their own brand.

Frequently asked questions
Do I need an app to tap an NFC card?
No. The person tapping your TapTrust NFC card doesn't need to install anything. Their phone's built-in NFC reader automatically triggers the link when they tap the card. Your smart profile and review prompt open directly in their browser.
How much does an NFC card cost?
TapTrust itself is free to start (3 smart profiles, basic tap tracking). Physical NFC cards are ordered separately and costs vary by quantity and print quality. Once you own the cards, they're reusable indefinitely. Pro and Business tiers unlock NFC tag writing, letting you reprogram your own chips without ordering new cards.
Can an NFC card store more than one piece of information?
A single NFC tap triggers one link (your TapTrust profile). However, your smart profile can include multiple pieces of information: contact details, links to your website, social media, portfolio, calendars, and lead forms. One tap, many destinations.
Are NFC cards secure?
TapTrust NFC cards direct users to your smart profile URL, encrypted and verified by Google. No sensitive data is stored on the card itself. Reviews go through Google's standard verification process, so fake reviews are filtered out.
Can I reprogram an NFC card once it's printed?
With TapTrust Pro tier and above, yes. You can write to NFC tags yourself using an Android phone, meaning you can change what your card does without ordering new cards. Free and Plus users work with pre-printed cards linked to their TapTrust profile.
What phones support NFC cards?
Most modern iPhones (XS and newer) and Android phones support NFC. When someone taps your card, iOS automatically opens the link without requiring a dedicated app. Android users may see a notification and can tap to open.
