San Diego-based Semtek, which develops technology for checking for credit card fraud at retail terminals, has raised $6.7M out of an $8.0M round, according to a filing from the firm earlier this week. Semtek had announced its round last week, saying the Series B funding came from VeriFone, Venrock, and RRE Ventures, but did not disclose any financial details of the funding. Semtek's technology protects the magnetic stripe on payment and credit cards.
