# PAX Terminals

> Overview of supported PAX payment terminals, device types, and the setup order for onboarding a merchant with PAX hardware.

Taliup supports two PAX terminal configurations. The correct setup steps depend on which device the merchant has.

    end
    paxstore --> hq
    hq --> ondevice
```

<Steps>
  <Step title="PaxStore setup">
    Create and activate the terminal(s) in PaxStore. Push the correct apps for the device type. Note the **TID** for each terminal — you will enter these in Taliup HQ.

    [PaxStore setup →](/taliup-hq/devices/pax/paxstore)
  </Step>

  <Step title="Add devices in Taliup HQ">
    Register each terminal as a **Device** in Taliup HQ using the TID from PaxStore. Device registration must be complete before the first login on the terminal.

    [Add PAX devices in HQ →](/taliup-hq/devices/pax/add-devices)
  </Step>

  <Step title="On-device setup">
    First login, connection configuration (PAX Elys only), pairing (PAX Elys only), and test sale. This is covered in the Taliup POS documentation.
  </Step>
</Steps>
