Internet and mobile sales continue to grow in popularity among shoppers and profitability for retailers. Last year, online sales in the U.S. topped $307 billion. The lucrative internet marketplace has also led to more online crime. Recent cyberattacks on U.S. businesses, which affected such titans of industry as Target, JPMorgan Chase, Home Depot and Premera, has Congress scrambling to craft laws to protect businesses and consumers against data breaches. And in 2014, businesses lost an estimated $3.5 trillion globally from retail fraud. Online sellers took the biggest hit, according to LexisNexis, primarily due to losses from card-not-present (CNP) transactions.
