How to Write Your Own NFC Tag with TapTrust
TapTrust Pro lets you write and reprogram your own NFC tags through the app, turning any compatible tag into a smart profile that collects leads and Google reviews when tapped.
What NFC Tag Writing Does
NFC tag writing is the ability to reprogram a physical NFC tag (a small chip or card) to point to a custom profile or action when someone taps it with their phone. TapTrust Pro includes NFC write functionality, which means you can take blank or existing NFC tags and configure them to load your TapTrust smart profile. When a customer taps the tag, your contact details, lead capture form, and Google review prompt appear instantly on their phone, no app download required. This is useful if you want to repurpose old tags, customise your own card stock, or embed tags into signage, merchandise, or packaging without relying on pre-printed cards.
How to Use NFC Writing in TapTrust Pro
Once you upgrade to TapTrust Pro (£5.99 per month or £49.99 per year), the NFC write feature becomes available in the app. You select which of your 5 profiles you want to link to a tag, then place a compatible blank NFC tag against your phone. The app writes the profile URL to that tag. From that moment on, anyone who taps the tag will see your smart profile, receive a lead capture form, and be prompted to leave a Google review. You can reprogram the same tag multiple times, so you can change which profile it points to whenever you need. As of 2026, this feature is exclusive to the Pro tier and above.
Which NFC Tags Work with TapTrust
TapTrust writes to standard NFC Type 4 tags (ISO 14443A), which are the most common format. Blank NFC cards, stickers, and key rings are all widely available online and cost between £0.20 and £1 each depending on format and volume. Your phone must have NFC capability (most modern iPhones from iPhone 7 onwards and Android devices). Before buying tags in bulk, test one with your device to confirm compatibility. The TapTrust app guides you through the write process and will notify you if a tag cannot be written.
Why Use NFC Tag Writing Instead of Pre-Printed Cards
Pre-printed TapTrust cards are convenient, but writing your own tags gives you control over card design, material, and cost. You can print custom designs onto card stock, add your branding, and embed NFC tags yourself. This is especially valuable for businesses running promotions, testing new profiles, or wanting branded merchandise that doubles as a lead capture tool. You can also reprogramme tags if your profile changes, rather than reprinting thousands of cards. For freelancers, estate agents, and networkers, this flexibility often justifies the Pro tier upgrade.
Lead Capture and Review Collection Through Tagged Profiles
Every TapTrust profile you link to an NFC tag includes a built-in lead capture form and Google review prompt. When someone taps your tag, they land on your profile, fill in their details (name, email, phone), and are invited to leave a Google review. You receive the lead data instantly, and reviews are routed through Google's verification system to ensure authenticity. TapTrust Pro includes a monthly £5 reward credit, so you can incentivise reviews with store credit or discounts. The Free tier allows 3 reviews per month, while Pro and higher tiers remove that limit.
Analytics and Tracking for Tagged Interactions
TapTrust provides real-time tap analytics for every profile and tag. You see how many people have tapped your tag, where they tapped it (location data), and what device they used. This helps you understand which tags or locations are most effective at generating leads and reviews. Business+ tier adds CRM export, so you can send all captured leads directly to your CRM or email marketing tool via CSV. This data is essential for evaluating ROI on your physical NFC campaign and optimising placement.
