Secure Fields is a light-weight alternative to Embed that can be used to
capture card data in a PCI-compliant way, while fitting uniquely into any
bespoke payment flow.

1. [Create an API key](/guides/payments/secure-fields/quick-start/key) which is needed to generate
   the signed JWT token in step 2.
2. [Set up a server-side SDK](/guides/payments/secure-fields/quick-start/sdks) to generate a checkout session.
3. [Add fields](/guides/payments/secure-fields/quick-start/embed) to a web page that will
   handle the capturing of card data.
4. [And finally create a transaction](/guides/payments/secure-fields/quick-start/transact) with the
   checkout session.
