Lack of demand or lack of interest from the banks to invest in the technology/security? I'd love to know why the US adopted "Chip and Signature" rather than "Chip and Pin". Requiring a signature is essentially worthless. My understanding was that it was a combination of US customers not being familiar with using a PIN and concern over where the liability lies if fraud occurs (the assumption being that if someone uses a PIN then the card owner gave them the PIN).
