That works until a country decides to hop across the international date line the day after they switch from DST to normal time, and the timestamp occurs three times ;)
Digital wrist watches can go 10+ years on a single battery, and they typically have transistors switching at 32kHz (as opposed to price tags, which could be completely static until you press a button).
The parasitic resistance will be orders of magnitude larger than your sample resistance, any detector capable of detecting the sample resistance would be completely swamped out by it.
They are measuring voltage, not resistance (the resistance is computed). It's impossible to measure resistance without current and some voltage across the resistance, and while the parasitic effects are small the resistance we're talking about (and hence the voltage across that resistance) is so small that second order effects introduced by the probe wires can have a real effect, for instance if the probe wires have a higher resistance that makes them more susceptible to electric fields, which in turn would show up as a voltage. So this is anything but trivial.
If a bank is comprised of 66% of their customers being narcos, the bank gets shut down.
You don’t get to facilitate in illegal shit and hide behind your legitimate customers. Likewise, if you are a customer of theirs and know they heavily transact with illegal services, it’s on you for getting blocked.
Their legitimate customers are. If that means getting the operator to clean up their act, so much the better. If they won't, then at some point their legitimate customers will suffer.
And will probably have to jump to a more expensive provider who isn't subsidizing them with spammer revenue.
