Retailers like Home Depot, which recently suffered a major data breach, have known for years about vulnerabilities in payment systems, but have chosen to ignore them, experts say.

Home Depot decided only in January to buy technology that fully encrypts payment card data the moment a card is swiped, The Wall Street Journal reported Monday. The home improvement retailer launched the project in order to avoid a breach on the scale of Target's.

The breach at Target in December compromised 40 million credit-card accounts and contributed to the ouster of its chief executive officer.
