Chip & PIN again in General Posted June 20, 2006 No the shops have never lied, but the card industry is a bit economical with the truth and how the sPIN it. When a retailer is presented with a Chip & Signature card they can't tell if it's Chip & PIN or Chip & Signature until the chip is read, and either a prompt to enter a PIN appears OR a transaction slip is produced for the cardholder to sign in the normal manner. Blame the Chip & PIN people, not the retailers. The quick way to get a C&S card - enter your PIN incorrectly three times. The card will be PIN blocked and only work with a signature. This happened to me (admittedly prior to 14th Feb) when I forgot the PIN. I'm not certain if it is the case now though.
