What happens if some angry dude peels off the QR code? No more parking? Or would it also accept fiat for redundancy?
You can have a digital QR code on the meter - harder to rip off. But you can never protect completely against vandalism. Someone could also destroy the cash meter...
Why meter? City/streets to zones. Zone has a hourly rate and simple code on the street signs, Start - your licence plate + zone code. Park anywhere in the zone. Currently done with SMS
Yeah either way. It’s just a concept. I think you could test different specifics in different locations. There’s absolutely more than one way this could work.
It's a awesome idea and perfect for BCH but you really don't need physical meters any more. Expensive. Very simple map + park pay app, posters/signs, admin soft /server to run, report
