    it allows any Target team member to easily
    sweep a store for skimmers

I'm unclear on how this is supposed to help - unless the skimmers are being installed by frickin ninjas it seems like they already needed insider cooperation.

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

If the target employee cannot see the skimmer detection tool, the terminal has been compromised. Most skimmers fit on top of the terminal which would obstruct sight of this tool/layer. There are videos online of these skimmers being "installed" and it takes about 1 to 2 seconds of work and it seems anyone can do it.

This tool is not permanently installed. It is a daily check for skimmers

It’s the former more or less - https://youtu.be/Sljmr8m88P8. They could do it on a lane that isn’t open (read no attention) just before a rush hour and hope it gets chosen.

I feel like this would be particularly easy at self checkout stations where there's usually like 1 employee handling a dozen or so stations. You can also get someone else to go "accidently" scan a pack of gum twice and hit the help button to have said employee come over and fix it. That would provide more than enough of a distraction to quickly place a skimmer on a different station.

Skimmer can be installed in seconds, just glued-on when the skimmer-guy is at the check-out.

Yup. Three seconds: https://www.youtube.com/watch?v=5b1axnNK-wI

A second guy distracting the clerk helps, too.
