The first step after registration is to create a campaign. Campaigns are logical groups for your NFC tags, like a specific marketing campaign or product line. You can create as many campaigns as you want, and under each campaign you can create as many URLs to sign as you please.
It could be anything: your home page, a social media account, or a registration page. Don’t worry, because you can edit it at anytime. We create a short URL that will eventually be signed and written to a NFC tag, making it a secure NFC tag.
There are two ways to write NFC tags. If you're just getting started and want to experiment, the easiest way is to use our Android app on your phone. If you plan to program lots of NFC tags you can use our API with an existing NFC tag writer or contact us and we can program them for you. Once you download the Android app, login as a registered user, go to your campaign, select the URL and press the write icon. The app will guide you from there. You will need an NFC tag with at least 500 bytes of memory. The app will ask you if you want to permanently write the tag or not (meaning you can write over it — the default).
The cryptography behind the product explains exactly how we sign tags. The short answer is that we use the NFC Forum Signature RTD 2.0 specification. This is the only open standard security specification for NFC tags. Its goal is to be interoperable with any implementation. The Secure NFC tags can be written by TrustPoint and can be verified by a third party, similar to web browser security (Transport Layer Security).
Organizations allow multiple people to collaborate on campaigns. Once you create an organization you can add users (provided they are already registered). When you create a new campaign you can create it under your own personal account or under one of the organizations you belong to.
We covered how secure NFC tags are created above, now learn how they are used.
