“An interlinked system is a far greater security risk than a decentralized one, with each state issuing ID cards according to its own rules. That’s because if hackers manage to penetrate it, they’ll have access to identity documents in all 50 states – not just one. That means hackers will be able to copy your birth certificate, your passport, your Social Security card, and any other document you submitted to get your ‘secure’ driver’s license. Moreover, since there’s no requirement that the data on your Real ID be protected in any way, private companies can use the information in it at will. Every retailer that requires identification will swipe your Real ID and then sell the data.”
