Morrisons booze bottle security tags.

[ian field]

Do the security tags on Morrisons booze bottles have one of those tiny 12V
car keyfob batteries in them?

There's a semi-cylindrical bulge on the back of the plastic moulding - I
think there's a battery in there.

Surely this would be prohibitively expensive.

Looks like a sealed for life assembly, they just throw it away when the
battery runs out.

In large quantities they're probably only a few bob each and save a fortune
in shoplifted booze.

No. Passive RFID tags have no inbuilt stored power but are energised
by the interrogator loop.

So what's the MN21 shaped bulge on the back of the casing?
