How to dispose of your expired credit card securely

Firstly, grab a pair of scissors and cut up your credit card into thin strips. Cut along the shorter edge. Or shred it.

Secondly, randomly distribute these shreds/strips across bins all over Sydney (at various times as well).

This only works assuming there is no-one stalking you as you dispose of your credit card strips, going through the bins and picking them up and sticking them back in together again.
