decentralised offline NFC reading - possible?
I had an idea for a work project, but not sure if it’s actually going to be cost effective or possible, now that I’m investigating it.
I want to run a ‘scavenger hunt’ type system, where clients can check in at each site with a tag - however, there’s no internet connection at most sites and a strong preference for a self contained system ie no mains power.
Initially my thought was to just put a regular NFC tag at each site and give each client a reader, but most of them are ugly, expensive, large, or all three; I also am having trouble figuring out how to have the reader ‘report back’ without a network connection or being physically connected to a computer. I could potentially have a read/write solution at each site instead and the client takes the tag, but not sure how to keep it small and self contained (I only have experience writing tags with my phone).
I know an app would be the simplest solution here but I would really like to have a physical item for clients to have. ‘The Lens’ at ACMI is very similar to what I’d like to do, but they don’t have the same space and power constraints obviously. https://www.acmi.net.au/lens/
Open to any and all suggestions!
