Cardholder verification is used to reduce lost and stolen card fraud.With magnetic stripe,the cardholder verification methods can be online PIN,signature,or no CVM required.The introduction of chip cards allows issuers to choose whether their cards support online PIN or offline PIN verification (Personal Identification Number).With online PINthe PIN entered by the cardholder is encrypted
and sent over the network to the issuer for verification as can be done with magnetic stripe transactions.With offline PIN verification,the PIN entered by the cardholder is sent fromthe PIN pad to the card for verification.To perform offline PIN verification,the card must securely store a reference copy of the cardholder’s PIN.
