Hi @Andee, thanks for reaching out!

You certainly can, though I wanted to point our that you’re responsible for any expired, declined, or disputed payments accepted while offline. In addition, if you're going to be doing this on a regular basis — you'll want to carefully consider that you must reconnect your device to the internet within 72 hours or the payments will expire.

Hope this helps. For complete details, have a look at this article: Process Payments with Offline Mode

Please let us know if you have any other questions or concerns. 🙂
