The present disclosure relates to a method and a system for aggregating card transactions to detect fraud globally, wherein transactions that take place when the issuer’s accounts are known to be in a sleep state condition or comparable condition. The present disclosure suggests collecting data from an issuer, where there is a failure to detect system-wide fraud. Thereafter, the issuers are enabled to share fraud findings that may include more than simply one card network’s cards. Also, the present disclosure enables cross-card program frauds to be detected and stopped considerably more quickly, consequently reducing the size of a fraud and providing law authorities with an earlier warning.
