Note: We have 13 other definitions of RFID in our acronym attic RFID is an acronym for “radio frequency identification” and refers to a technology in which digital data encoded in RFID tags or smart tags (defined below) is captured by a reader via radio waves. RFID is similar to barcodes in that the data in a tag or tag is captured by a device that stores the data in a database. However, RFID has several advantages over systems that use barcode asset tracking software. Most notably, data from RFID tags can be read out of the line of sight, while barcodes must be aligned with an optical scanner. If you are considering implementing an RFID solution, take the next step and contact AB&R`s® (American Barcode and RFID) RFID experts. The design of the chip and antenna controls the range from which it can be read. Short-range compact shavings are twisted with the shoe or attached to the ankle with Velcro fasteners. The chips should be about 400 mm from the carpet, which gives a very good temporal resolution. Alternatively, a chip and a very large antenna (125 mm square) can be integrated into the bib number, which is worn on the athlete`s chest at a height of approximately 1.25 m (4.10 ft).

RFID (Radio Frequency Identification) is a form of wireless communication that involves the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person. In 2004-2005, Federal Trade Commission staff held a workshop and review of RFID privacy concerns and published a report recommending best practices.  Some people fear the loss of their rights due to the implantation of a human RFID. RFID technologies are now also being used in consumer applications in museums.  One example was the custom temporary search application “eXspot” at the Exploratorium, a science museum in San Francisco, California. A visitor who entered the museum received an RF tag that could be worn as a card. The eXspot system allowed the visitor to obtain information on specific exhibitions. In addition to the information about the exhibition, the visitor was able to take pictures of himself in the exhibition. It should also allow the visitor to extract data for later analysis. The information collected could be retrieved at home from a “customized” website linked to the RFID tag.  Hitachi holds the record for the smallest RFID chip with 0.05mm × 0.05mm. That`s 1/64th the size of the previous record holder, the mu chip.
 Manufacturing is made possible by the use of the silicon-on-insulator (SOI) process. These dust-sized chips can store 38-digit numbers with 128-bit read-only memory (ROM).  A major challenge is the attachment of antennas, which limits the reading range to millimeters only. Some countries require a site license, which must be applied for from local authorities and can be revoked. [ref. needed] Physicians should inquire about the use of RFID systems. If a patient has a problem with a device, ask questions that help determine if RFID could have been a factor, such as: when and where the episode occurred, what the patient was doing at the time, and whether the problem was resolved once the patient moved away from that environment. If you suspect that RFID was a factor, a query on the device may be helpful in correlating the episode with exposure. Report any suspected malfunction of a medical device to MedWatch, the FDA`s voluntary adverse event reporting system. Smart tags are simple RFID tags. These tags have an RFID tag embedded in an adhesive tag and have a barcode. They can also be used by RFID and barcode readers.
Smart labels can be printed with desktop printers on demand when RFID tags require more advanced devices. One of EPCglobal`s missions was to simplify the Babel of protocols prevalent in the RFID world in the 1990s. Two day-to-air interfaces (the protocol for exchanging information between a transponder and a reader) were defined (but not ratified) by EPCglobal prior to 2003. These protocols, commonly referred to as Class 0 and Class 1, were implemented commercially in 2002-2005.  Although a variety of secure protocols for RFID tags have been proposed, many RFID tags barely have enough power available to support very weak and, therefore, simple security protocols such as coverage coding to support long, low-cost read ranges.  The NFL in the United States equips players with RFID chips that measure the speed, distance, and direction of each player in real time.
