I have a set of Dev kit devices that are currently provisioned to the sandbox account. Mainly the reason they were adquire was for demo purposes. The sandbox does not provide third parties applications. Also on the dev account (Not Sandbox) I'm able to see and installs Third parties apps. Is there a different kit that needs to be use for demoing since I can't provision my dev devices outside of the sandbox account.
Sandbox/Dev Kit devices will not work as DEMO devices, they're intended for Development purposes only. First Data used to have DEMO devices, I suggest you contact your merchant services provider ( ;p) and channel the question through them.
