Hi all,
I'm new and not any form of electrical engineer. I've got a small project in mind and I'm wondering what it would take - or indeed if anything like it actually exists.
I would like to control flow of electricity to a device (an appliance) by inserting (or otherwise) a programmed RF tag (or other very-near proximity control method). Scenario: I want to give permission to only certain people to use said device - Person A is authorised so if they insert their personal tag containing the relevant credentials the electricity will flow and they can use the device; Person B is not authorised and their tag does not have the relevant credentials therefore electricity does not flow.
I realise that some of this scenario requires other technology (i.e. software) to run - checking credentials against a database etc.
However is it possible to have a unit that controls flow of electricity in response to user credentials? Happy to hear any and all ideas, I'm not glued to any one approach.
Cheers,
rjh
