Toying with an idea. Know it's not new by any means, but was hoping to get some feedback before implementation. Especially if it's from someone who has used/does use this method.
Don't know why I didn't think of it before, but when scanning some things like blurays I'll hear that weird little like three second growl (honk?) sound. I assume that's the tag being demagnetized?
So... couldn't I switch the tag, scan it, and treat it like business as usual? Most (all?) source tags are by the upc so cashiers can scan, deactivate, bag in one motion right? And like it'll demagnetize regardless of what tag is used?
(Also, completely unrelated, does LEGO source tag? Guessing not hence why some kits have the spider-wrap... ?)
