[Gabe Schuyler] had a irritating downside when it got here to moving into his constructing’s storage. The RFID entry system meant he needed to take away his gloves whereas sitting on his bike to fish out the keytag for entry. He decided to whip up a better solution with less fuss.
His preliminary plan was to duplicate the keytag and to stitch one into his gloves. Buying a 125 KHz RFID tag duplicator off eBay, he was capable of shortly copy the tag, and create one which labored together with his storage’s entry system. Whereas the duplicate tags labored properly, they had been nonetheless too huge to simply match right into a glove. Makes an attempt to create a reproduction with a smaller tag failed, too. Ultimately, [Gabe] turned up a hoop full with a appropriate RFID chip, and was capable of duplicate his entry tag onto that. Now, by carrying the ring, he can enter his storage and constructing with a easy wave of the hand, gloves on or off.
After all, duplicating an RFID tag is not any main hack. As per [Gabe]’s Shmoocon talk on the topic, nonetheless, it exhibits that many buildings are utilizing fully insecure RFID entry strategies with little to no safety in any respect. Anybody that discovered an entry tag mendacity on the bottom may simply replicate as many as they needed and enter the constructing unimpeded. It additionally bears noting which you could snoop RFID playing cards from further away than you might expect.
