 | | Chip and PIN removes some of this threat — the retailer is (in principle) not supposed to touch the card, reducing our* opportunities to swipe magnetic strips, and we cannot obtain signatures. |
 | | Chip and PIN raises the bar from copying a magstripe and trivially obtaining a signature to theft (or difficult copying) and very time-dependent shoulder surfing (the PIN is encrypted at point-of-entry, unlike a paper signature, and cannot be extracted later). |
 | | By introducing Chip and PIN, they limit the possibility of fraud by the retailers, while increasing the threat from members of the public. |
