Sometimes I've make my own picks - out of old debit cards, phonecards etc. Fiddling about with 'cut anything' scissors then finishing the edges with wet/dry paper. I wondered how long it would be until someone invented something to make them instantly - and now they have. I've just ordered two (one for me and one for a friend).

I thought it was good mainly for the convenience/fun factor rather than landfill.
Security?! it makes picks as well as destroying the card ! The bit with the chip could be broken up and thrown away.
