I would like to implement a stand alone device with features that can also connect via wifi for minimal IOT support.

these people seem to have implemented this idea

but its not clear if their system will allow personalize and removal of their brand. looking to do something similar but with personalization and customization of my own.

Wouldn't mind programming it myself from the ground up. Wondering which reader would do approximately 8.5m? Any ideas would help. Thanks
