“There are 420,000 ATMs in the U.S., and on April 8, a deadline looms for nearly all of them that underscores how sluggishly the nation’s cash delivery system moves forward. That’s the day Microsoft cuts off tech support for Windows XP, meaning that ATMs running the software will no longer receive regular security patches and won’t be in compliance with industry standards. Microsoft’s 12-year-old Windows XP dominates the ATM market, powering more than 95 percent of the world’s machines and a similar percentage in the U.S. ATMs whose operators ignore the deadline will continue to function; they’ll just become more vulnerable to malware and other attacks.”
