Dear WO-ers, I need your expertise.

I want to have a defined set of tablets (iPad) tied into my application. Th= e tablets act as a satellite device in the context of a customer checking i= nto a clinic. The person comes up to the registration desk and is checked i= n. The receptionist sees that there is some registration data missing and hands the patient a tablet with the = running application (or directs the customer to "use the green screen = over there=94). The receptionist should now be able to remotely open the re= gistration screen on that green iPad, the customer filling in the data and then pressing Save.

My train of thoughts goes like this:

As a one-time operation an admin opens the application from that green iPad= , goes to a registration screen, and creates a =93Satellite" entry in = the database. This entry gets a UUID (or something similar) and that UUID s= hould be put into the green iPads Web Storage.

I need to identify the polling iPad and I want to pre-register the iPad as = a security measure.

How would you tackle such a requirement?
