Neodymium Magnets and Tags

[nostrumfiend]

Can neodymium magnets disable sensormatic strips and/or RFID tags inside of boxes?

For example, say there was a serial number someone wanted to get that was inside of a box. Could someone rub the magnets all over the box for a minute or two and would that effectively ruin the security of the box and allow someone to leave without setting off the alarms at the entrance/exit of a store?


These are the kinds of tags I'm talking about.

I'm just wondering if ordering some neodymium magnets online would be a wise investment.

If the magnets are capable of doing what I asked, what size, quantity, and strength would be required?
