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.

答案
