Prove what's valuable is real, in one tap. TAGBASE Writer turns blank NFC tags into verifiable proof. Define what you want to protect in the TAGBASE web portal, open the app, select it, and hold your phone to the tag. Every tag is configured with the same security standards used in mass production. What you can protect: • Jewellery: proof of authenticity in every piece • Documents: certificates and records that are impossible to forge • Maintenance: proof that the work actually happened • Products: the authenticity you already trust These are a few of the possibilities. Because TAGBASE is a platform, you can build the same verifiable proof into your own products and workflows. How it works: 1. Create your item in the TAGBASE web portal 2. Open Writer and select it 3. Hold your phone to the tag, done Verify anywhere: Tap any TAGBASE tag with your phone to confirm it is genuine, on the spot, with no extra hardware and nothing to install for the person checking. Built for smaller-scale and custom setups, where configuring tags yourself gives you maximum flexibility. Write one tag or work through a batch, at your own pace. In this version we rebuilt the app end to end, so writing and verifying tags is faster and steadier. Requires an iPhone with NFC and a TAGBASE account.
