Anybody know of any good penny stocks for RFID technology. Obviously Unova owns the patent rights, but who's taking the most advantage of this technology? Thanks in advance.

What is RFID:
RFID (Radio Frequency IDentification) A wireless data collection technology that uses electronic tags for storing data. Like bar codes, they are used to identify items. Unlike bar codes, which must be brought close to the scanner for reading, RFID tags are read when they are within the proximity of a transmitted radio signal.
RFID Tags Store More Data
Because RFID tags hold more data than bar codes, which generally contain only a product ID, the RFID tag can be used for tracking individual items. For example, one of its first uses was to track livestock and other animals. Taking that a step further, in 2004, an amusement park in Denmark launched a child tracking system that uses RFID wrist bands. If children are lost, they can be found by the numerous readers around the park. Tags are also attached to retail products for security purposes, and libraries use them to track books and videos.

My personal favorate is Samsys Tech. SMY on the TSX Exchange (SMSSF). The company is working with UNOVA and Microsoft. http://samsys.com/ What is RFID?
RFID TechnologyIn the simplest terms an RFID system consists of a tag (transponder) and a reader (interrogator). The technology of RFID deals with the remote collection of information stored on a tag using radio frequency communications. Information stored on the tag can range from as little as an identification number, to kilo-bytes of data written to and read from the tag, to dynamic information maintained on the tag, such as temperature histories. The information from the tag/reader combination is either presented to a human operator typically using a hand-held device with a alpha-numeric display or a host computer which automatically manages the information.
Critical performance variables in an RFID system involve the range at which communication can be maintained, the size of the information space contained on the tag, the rate at which the communication with the tag can take place, the physical size of the tag, the ability of the system to "simultaneously" communication with multiple tags, and the robustness of the communication with respect to interference due to material in the path between the reader and the tag. Several factors determine the level of performance that can be achieved in these variable. The factors include the legal/regulatory emission levels allowed in the country of use, whether or not a battery is included in the tag to assist its communication back to the reader, and the frequency of the RF carrier used to transport the information between the tag and the reader.
Frequency Over the course of decades of RFID development, industry has evolved RFID solutions that variously trade the regulatory constraints, the signal propagation characteristics of various RF carrier frequencies, and the economics of tag size and optional batteries. These solutions employ only a few RF frequencies around which the vast majority of RFID systems are fielded today. The RF frequencies include relatively narrow bands centered at:
125/134KHz or low frequency (LF) 13.56MHz or high frequency (HF) 433/869/915MHz or ultra-high frequency (UHF) 2.45/5.8GHz or micro-wave (uW) These frequency values are commonly referred to the RFID technology. Thus, tags and readers combinations are described as employing LF, HF, UHF, or uW technology.
