Blocking fraudulent debit card activity

In our global economy, debit card fraud can take place anywhere in the world! SACU uses TranBlocker, a Web-based tool that allows us to better control debit card fraud by blocking transactions where the incidence of fraud is high.

However, even in blocked countries or within certain merchant categories, SACU members are able to use their SACU debit cards in the United States or in foreign countries by conducting a PINNED transaction.

In the event your debit card is denied or for more information, please call our Member Service Center Monday-Friday 8 a.m. to 6 p.m. Central Time at (210) 258-1234 or U.S. toll free at 1-800-688-SACU (7228).

TranBlocker to the rescue!

  We can remove a block on your debit card if you request it, often the same day you call Monday - Friday 8 a.m. to 6 p.m. Central Time at (210) 258-1234 or U. S. toll free 1-800-688-SACU (7228) or contact us by email.
