Making Your Application Available on Production PAX Devices {#pax-aio-submit-app-for-prod-pax-device-intro}
===========================================================================================================

Use this information to make your app available for use on production (live) PAX devices.  
The difference between a production and debug PAX device is that a debug device ordered from `Cybersource` has a *DEBUG only Not for COMMERCIAL* watermark in the bottom-right corner of the device screen. A production device does not have a watermark. For more information about debug devices, see [Installing Your Application on Debug PAX Devices](/docs/cybs/en-us/pax-all-in-one/integration/all/na/pax-all-in-one/pax-aio-get-started-intro/pax-aio-install-app-on-debug-pax-device-intro.md "").  
You must prepare and submit your app before it can be added to PAXSTORE, which is a PAX Technology platform where you can publish your point-of-sale (POS) device apps.

Before starting the app submission process, verify that your APK file is not larger than 200 MB.  
Follow these steps to submit your Android application.
