In one embodiment, a rotatably adjustable head is mounted on the compact reader body portion containing read/write electronics and an interface controller. The rotatably adjustable head contains an antenna and is adapted to direct the antenna in numerous different directions without moving the compact reader body portion of the rf reader. Additionally, in one embodiment, the rf reader unit includes a switching power supply located within the reader body portion. The switching power supply is electrically coupled to the read/write electronics and the interface controller, and is synchronized with the transmitting frequency of the antenna to prevent interference.
