An 18-year-old Johns Hopkins University student recently returned home from a trip and received her first overdraft email ever. She suspected identity theft, but was shocked to find a $23,148,855,308,184,500 charge on her statement from what she thought was a $10 train ticket purchase. Plus a $20 negative balance charge from Wachovia Bank, of course.
After she Googled how to pronounce the sum, a call to Visa reversed the charge. The company had suffered "a temporary programming error" during a system upgrade that resulted in some pretty wacky and inflated transactions. A spokesperson told the NYT, "No one was actually charged $23 quadrillion."
