Criminals hope by using threats of enforcement action, people will panic and click link to bogus parking app site

You use parking apps a lot – you have several on your phone – but it is not always straightforward. Sometimes there is a lack of reliable mobile signal, or the app crashes or behaves oddly, or it does not seem to want to accept your bank card.

Also, it is sometimes hard to keep track of which apps you have used when. So when you receive a text from RingGo saying you owe it money, you are not totally surprised.
