"In the survey, nearly half of respondents said they are extremely concerned about their personal data when shopping in stores since the breach. Sixty-one percent said they have deep worries when spending online, while 62 percent are very concerned when they buy on their mobile phones.

And even fewer have changed their online passwords at retailers’ websites, requested new credit or debit card numbers, or signed up for a credit-monitoring service."
