Endnotes 73 summary RFID is a tricky technology to secure. It is wireless, and as such, communications can be read at a distance and captured. Due to their small size, the options for encryp- tion are limited and often rolled by the manufacturer themselves instead of peer- reviewed algorithms, which can lead to them being defeated with ease. In the end, any system based on RFID should ask the following questions from the beginning: "What do we do if this fails?" "If a tag is cloned, what will the effect be?" "Is there another layer of protection that will minimize the impact if this occurs?" "What is the organizational structure around the use?" "Is it possible to audit its use and monitor for irregularities?" All are tough questions that must be answered. RFID is a young technology, and developers and society are still adapting to what it all means. There is no simple solution and it is up to the integrator/user of the sys- tem to actively think about what the system's authentication scheme means in a grand sense. Simple authentication with a card may be good at limiting access to the front door of a building from the general public, but perhaps not the crown jewels. RFID- enabled credit cards may seem convenient, but one must weigh the convenience of this against the possibility of a drive by skimming of the credit card details. In that
