![]() Unfortunately, the RFID reader in question is currently out of stock at Deal Extreme. Exactly why it does this is anyone’s guess, but since figured out how it worked, he could also figure out how to reverse the process. So what’s going on here?Īs it turns out ( Anglais), this random piece of Chinese electronica sends 10 bytes of data to the computer, just like this well-documented RFID reader. Apparently, both these RFID readers take the hex value of an RFID card, convert those bytes to base 10, and pass each digit through a lookup table. ![]() ![]() The only problem was these characters weren’t the hex values recorded on the RFID card. The RFID reader presented itself to his computer as a USB HID device that spit out characters into a text editor whenever an RFID card was waved above the coil. When the USB RFID reader arrived, he noticed something fairly odd about it (French, Traduction). Ran across a very, very inexpensive RFID reader on Deal Extreme a while ago and with money to burn, added it to his cart.
