A grand total of 96 fraudulent credit cards traced back to the Target data breach were found at the Texas border.

About 40 million credit and debit card accounts of all brands, and information like card numbers, expiration dates, customers names, encrypted PINs and security codes embedded in the cards' magnetic strips were stolen in the breach.

Mexican citizens Mary Carmen Garcia, 27, and Daniel Guardiola Dominguez, 28, were arrested Sunday while trying to cross the border with the cards, according to police in Texas.

The cards they were found with contained the account information for South Texas residents, indicating that the data stolen in the breach is being sold regionally. The data can fetch between $20 and $100 on black market websites, the Associated Press reports.

Officials in the U.S. were waiting for Garcia and Dominguez with arrest warrants after a number of retailers in McAllen, Texas, were hit with fraudulent purchases earlier this month. The two may face federal charges in the case.
