Parking machines had a chip implanted inside programmed to rip off punters paying to park all day,it was rigged to short change you,then hope that you would not noticed that you have paid in full,only to find that your car was clamped and towed for £300,reclaiming the car at their pound,they say you did not put enough money in their swindle machines.
The boss got 2 years for fraud,his name was on the chip left in the machine.The machine would print out a false reading on the ticket.
easy, wait for all coins to register, check the money and time on the ticket if its wrong phone the number on the machine. Trust me most ticket machines arn’t complex enough to have ‘scam chips’ in them
