If you make sure who is doing the skimming rotates so that there is a constant stream of new people checking it would be really hard to stop detection in a timely manner. It's also insanely fast to install a skimmer (like 2 seconds fast) so you don't necessarily need insider help. Until wireless skimmers with a decent range become available this tool could bring skimming down to effectively zero (and reduce it to just the customer who rang through the till before it was discovered when they are available). It's a pretty epic addition to the retail security landscape
