What Is NFC Tag Writing and How Does It Work?
NFC tag writing is the ability to re-program NFC cards or tags so they trigger a specific action when a customer taps them on their phone. TapTrust by MRVL uses NFC tag writing to let you turn any compatible NFC card into a smart profile card that collects Google reviews and captures leads instantly upon tap.
NFC Tag Writing: The Basics
An NFC tag is a small chip embedded in a card, sticker, or object. When you write data to an NFC tag, you're encoding instructions that tell a phone what to do when it reads the tag. Most NFC writing happens once during setup, but some apps like TapTrust let you re-program your own tags multiple times. This means you can update the action a tag triggers without buying a new card. For example, you could change what profile loads when someone taps your card, or redirect them to a different review prompt, all without replacing the physical tag itself.
How TapTrust Uses NFC Tag Writing
TapTrust's Pro and higher plans include NFC tag writing capability. When you have NFC write access, you can programme your own compatible NFC cards to load your TapTrust smart profile instantly. A customer taps the card on their phone, your contact details and Google review prompt load in seconds, they leave a review, and you capture their details as a lead. The card acts as both a digital business card and a review collection tool in one physical object. Because the tags are re-programmable, you can update your profile link, contact information, or review prompt without needing new cards printed.
Who Should Use NFC Tag Writing?
NFC tag writing with TapTrust suits freelancers, estate agents, mortgage brokers, salon owners, restaurant managers, and any client-facing professional who wants to streamline how they collect reviews and capture leads. Instead of handing out paper business cards or asking customers to search for your business online, you give them an NFC card they tap once. The tap is instant, frictionless, and you get real-time analytics showing where and when each person tapped. If your business model relies on verified reviews and lead data, re-programmable NFC cards eliminate the need to reprint cards each time you want to adjust your review prompt or profile content.
TapTrust Pro vs Free and Plus Plans
TapTrust's Free plan lets you create one smart profile and share it via QR code or link, but does not include NFC tag writing. The Plus plan (£24.99 yearly or £2.99 monthly) gives you three profiles and unlimited reviews, but still no NFC write access. The Pro plan (£49.99 yearly or £5.99 monthly) unlocks NFC tag writing, plus five profile cards, £5 monthly credit, and 3x reward streaks. Business+ and Enterprise plans add CRM export, team management, custom domains, and white label options. As of June 2026, NFC tag writing is exclusive to Pro tier and above.
Compatible NFC Cards and Setup
To use TapTrust's NFC tag writing feature, you need NFC-compatible blank cards or tags and a mobile device running iOS or Android. Once you download the TapTrust app and upgrade to Pro, you can programme your own tags directly from the app. The process is straightforward: select the profile you want the tag to load, hold a blank NFC card to your phone, and tap 'write'. After that, anyone who taps the card will instantly see your smart profile, with your contact details, location map, and Google review prompt pre-loaded. No barcode scanning, no typing a URL, no signup required from them.
Why NFC Tag Writing Beats QR Codes for Reviews
QR codes work for review collection, but NFC cards are faster to scan and require no camera app. A customer simply holds your NFC card near their phone for a fraction of a second, and your profile loads. With QR codes, they must open a camera, frame the code, wait for the link to register, then tap. NFC is also re-programmable, so you can update your review prompt, add a new business location, or change your profile content without reprinting cards. QR codes are static and require a reprint if your content changes. For businesses collecting reviews at high volume, the NFC experience is smoother and drives higher completion rates.
