Abstract:
Systems and methods for performing token transactions are provided. In one embodiment, the invention provides for processing token transactions, including receiving an encrypted password for a debit card transaction, wherein the password was secured using encrypted debit-card information, decrypting the password using encrypted debit-card information for the debit card, recreating the password using actual debit-card information for the debit card, and forwarding the recreated password for subsequent transaction processing. The invention is suitable for implementation with other types of tokens in addition to debit-card tokens as well. The invention can be implemented in a scenario where the password includes a PIN block that is created by combining a clear or encrypted PIN for the token with token information.
