plover sends this news about another possible exposure of customer data: Supervalu is the latest retailer to experience a data breach, announcing today that cybercriminals had accessed payment card transactions at some of its stores. The Minneapolis-based company said it had "experienced a criminal intrusion" into the portion of its computer network that processes payment card transactions for some of its stores. There was no confirmation that any cardholder data was in fact stolen and no evidence the data was misused, according to the company. The event occurred between June 22 and July 17, 2014 at 180 Supervalu stores and stand-alone liquor stores. Affected banners include Cub Foods, Farm Fresh, Hornbacher's, Shop 'n Save and Shoppers Food & Pharmacy.

    There are typically two phases to processing credit. In the first phase, called authorization, the terminal sends the request to the bank via their processor and requests authorization: hey, bank, will you approve $100? The bank sends back a 'yes' which is returned to the terminal, but no money changes hands at this time. The processor saves up the day's batch of authorization requests.

    In the second phase, called settlement, the processor sends the batch to the bank, either later that night, or every few hours, or whenever. The bank then transfers the funds for every authorized transaction in the batch.

    This is different from debit, where the funds are transferred in a single step.
