Ask HN: Strong magnet in Logitech mouse box
I recently bought a Logitech MX Anywhere 2S mouse and when I was flattening the box I noticed it had a small battery like disk inside. I assumed it was an RFID tag. When I was tossing it in the trash it flew out of my hand and stuck the metal trash can.
On first glance it looks like a "357" battery [that is the small battery a little less that 1/2 across that is very common in laser pointers, small flashlights, etc].
Does anyone know why an RFID tag (if that's what it is) would have such a strong magnet in it?
- andreicon 7y agoMy rolling papers also have a magnet on the box, it helps keep the lid closed.
- chunkles 7y agoSome packaging now comes with a magnetic clasp to hold the lid of the box shut. I've seen it on several electronic product boxes. If you look kart the packaging, there may be a small metal strip embedded under a strip of paper that the magnet would have been in line with.
