RFID tags are available in several frequencies. The ones read by the equipment in this article are based on UHF. Hackers have already demonstrated homebrew equipment that can read UHF RFID tags from 69 feet. Most credit cards are based on ISO-14443, which uses a much longer wavelength than UHF tags and typically claims a maximum read distance of a few inches. Hackers have demonstrated low-cost reading equipment with a range of about a foot. The gear in this article is newsworthy for its impressive read-rate performance at these distances, and not just for its long distance reach. Something like this could work well covering an entire loading dock, for example.
