# The TAGBASE Writer app

Get the TAGBASE Writer app for iPhone and Android, sign in, and write your tags.


There are two ways to get working TAGBASE tags:

- **Preconfigured tags** — the default.
  [Order tags](/docs/team-and-settings/orders-and-billing) and we ship them
  ready to use: apply them to your products, and they work. We make sure you
  always get the correct tags.
- **Tags you write yourself** — for testing, experimenting, and small
  batches. Source blank tags on your own and configure them with the TAGBASE
  Writer app. TAGBASE works with specific dynamic NFC tags, so ordering
  compatible blanks is up to you.

Most teams go with preconfigured tags and never need the Writer app. If you
write your own, it turns your phone into a tag writer: hold a blank tag to
it, and the app sets it up and links it to your product. Your customers
verify products in a browser without installing anything.

## Get the Writer app

The app is free on both stores. Point your phone's camera at the code for
your platform, or tap the badge to open the store page.

## Sign in and link your team

Open the app and sign in. The app hands you to the browser: sign in with
your TAGBASE account, then pick the team that holds your tags — or link
your Verify team. You can switch teams later from the app's account menu.

## Write a tag

Pick a product in the app and hold a blank TAGBASE tag to your phone. The
app sets the tag up and links it to your product. The tag is live from that
moment.

tag — see [your first product](/docs/getting-started/your-first-product).
