[Gabe Schuyler] had a disheartening issue when it came to acquiring into his building’s garage. The RFID accessibility method intended he had to remove his gloves even though sitting on his bike to fish out the keytag for entry. He resolved to whip up a much better answer with less fuss.
His original approach was to copy the keytag and to sew just one into his gloves. Getting a 125 KHz RFID tag duplicator off eBay, he was capable to rapidly duplicate the tag, and generate one particular that worked with his garage’s entry system. When the copy tags labored perfectly, they had been even now way too big to quickly in shape into a glove. Tries to make a copy with a smaller tag failed, way too. At some point, [Gabe] turned up a ring total with a compatible RFID chip, and was in a position to duplicate his entry tag on to that. Now, by carrying the ring, he can enter his garage and setting up with a easy wave of the hand, gloves on or off.
Of training course, duplicating an RFID tag is no significant hack. As for each [Gabe]’s Shmoocon converse on the subject matter, having said that, it demonstrates that several properties are applying absolutely insecure RFID access methods with little to no stability in anyway. Any person that identified an obtain tag lying on the ground could easily replicate as numerous as they wished and enter the setting up unimpeded.
