I needed to park down in Monthey today, at a surface parking I’ve used a number of times, and recently have always used Twint to pay for it. It’s ticketless, one of those where you would normally go to the payment machine, type in your number and enter the desired length of time, then put coins in the slot. No barrier, no number plate recognition or anything like that.
So anyway. today I had a dental appointment, wasn’t quite sure how long it would be, put in 40 minutes and the Twint app tells me it’s succeeded, shows me the end time.
So once I get to the dentist, only a couple of minutes walk away, they are running a little late, so I go into the app and look at the remaining time, and see that it shows me I can cancel the payment, doesn’t seem to allow me to modify it, but cos it’s still within ten minutes (or whatever the limit might be) it shows me a full refund if I cancel.
So that’s all OK, my 70 cents is refunded, then I put in the expected new finish time, shows me 70 cents again, so OK, done.
What I want to know is this: what would have happened if the wardens had come along in the first ten minutes before I cancelled it, or indeed if they had done so in the minute or so between me cancelling it and doing the second transaction? (I did once get a ticket there pre-Twint when my time had expired, so I know they do check),
And would it be possible (just in theory, cos I’m sure not going to bother for just a few cents) to extend the parking time indefinitely by repeating the process, enter time, pay, wait ten minutes, cancel and repeat?
