Many banks are now issuing customers more secure chip-based credit cards, and most retailers now have card terminals in their checkout lanes that can handle the “dip” of chip-card transactions (as opposed to the usual swipe of the card’s magnetic stripe). But comparatively few retailers actually allow chip transactions: Most are still asking customers to swipe the stripe instead of dip the chip. This post will examine what’s going on here, why so many merchants are holding out on the dip, and where this all leaves consumers.

Buried in the federal indictments unsealed this week against four men accused of stealing tens of millions of consumer records from JPMorgan Chase and other brokerage firms are a series of other unnamed companies that were similarly victimized by the accused. One of them, identified in the indictments only as “Victim #12,” is an entity that helps banks block transactions for dodgy goods advertised in spam. Turns out, the hackers targeted this company so that they could better push through payments for spam-advertised prescription drugs and fake antivirus schemes.

The move marks a departure from the far more prevalent “chip-and-signature” standard, an approach that has been overwhelmingly adopted by a majority of U.S. banks that are currently issuing chip-based cards. This post seeks to explore some of the possible reasons for the disparity.

The malicious software that unknown thieves used to steal credit and debit card numbers in the data breach at Home Depot this year was installed mainly on payment systems in the self-checkout lanes at retail stores, according to sources close to the investigation.
