I'm not sure if the term "phishing" even applies here. The scam would be straight up fraudulent credit card billing -that most users wont even notice.
During the processing part, The scammers could very well just overbill the user by saying "Do you agree to $2 for parking?" and then charge the user $50. Then say a "We will hold $50 while the transaction is approved" just like a gas station.
Your service will get all the complaints and the scammer just gets the cash.
I'm not saying it's a bad idea or anything, however there are many bored smart teenagers and many hungry people with sliding ethics.
Hell, an even better scam is to copy your QR code from each unit and then bill the user for $X more as a "convenience fee" ... then auto-submit correctly to your service.
I mean, that might not even be illegal [in the sense that the customer agreed to the fee].
