About some anti-shoplifting tags...

[konnfee]

I was kinda wondering... Those long, white, plastic tags that "hang" from clothing and other items, what are they called? Can they be beaten with a magic bag?

Thanks

EDIT: I think THESE (http://www.mbm-tt.net/Sensormatic/Sensormatic-HardTags/UltraGator.jpg) are the ones i mean
