In order to work properly, it has to be earthed. Otherwise it simply acts as a big retransmission aerial to the devices inside.
It might help, a bit, but it is a poor solution, to problem which is non-existent anyway.
Since, as I have pointed out, such transactions would all be detectable and reversible. Dead easy for the authorities to track down the perpetrators of such a crime.
It's fine to keep repeating the point about all potential cashless transaction-issues being 'detectable and reversible', but that's ignoring the point that we'd no doubt have to wade through the awful labyrinthine bank-processes to actually get them sorted out....
We're covered with all sorts of insurances that mean we'll often get back to where we started were the worst to happen, but it's the hassle involved in getting sorted out that's the biggest pain....
If these cashless transactions are error-prone, either due to simple theft or mistakes in the readers, then it's the same story - we might get back what we're owed, but it's most likely to be a right royal pain to do so....
Give me cash any day....
God almighty - I've finally turned into my Dad.....
