While there are scanners meant to read multiple frequencies, animals who may be traveling to locations outside the US would be best served with ISO standard chips. The global standard for microchips in animals, established by the appropriately named International Standards Organization (ISO), is the frequency of 134.2 kHz (kHz = kiloHertz = 1,000 wave cycles per second you can insert your own OJ joke here if you deem it necessary).
As you may (or may not) remember from physics class: as wavelength gets longer, the number of waves that can occur in a given time period gets smaller, and therefore the lower the frequency shorter wavelengths allow more repetitions in the same amount of time, hence higher frequency. While they all use the same concept, some products use different lengths of radio waves to transmit the stored information. In the US, there are many different brands of microchips used in pets. Of course, this does raise the dilemma of how you will locate the transmitter to replace the batteries when they wear out. There is an active form of RFID, which has a greater range, but batteries are required. Usually these are passive RFID tags, which have no battery and rely on the power provided by the scanner. It can also be found in library books, passports, luggage tags, Saguaro cacti, theme park tickets, golf balls (making every shot is a chip shot) and poker chip chips. It has many other applications including, but not limited to: product tracking, timing marathon runners, the EZ pass toll system and bovine ear tags (cow and buffalo chips). The technology used for microchips is known as radiofrequency identification (RFID). The microchip responds with radio waves (via a copper coil antenna) that transmit the digital data to the scanner and the id number is displayed on an LCD screen. A tuning capacitor within the microchip capsule receives electromagnetic power from the scanner and transfers the energy to the chip.
There is no power source within the chip assembly, so a scanner (or reader) is necessary to retrieve the information. Inside the capsule is the tiny silicon computer chip itself that contains the identification number. It may also feature a polypropylene polymer cap that, upon insertion into the body, stimulates the growth of fibrous connective tissue around the chip to prevent it from moving to another part of the body, or out of the body altogether. The capsule is made of nontoxic glass material.
The microchips implanted in animals (and yes, Mulder, in some case humans) are usually contained within a 12 mm long capsule (approximately the same size as a grain of rice). I shall now attempt to summarize it in a coherent manner. Along with a plethora of diversions about other fascinating topics, has a wonderfully in-depth explanation of the inner workings of a microchip. The microchips being recognized are those used for identification, not the crumbs at the bottom of a bag of Lay’s.Ī microchip is described succinctly (by the AKC) as a radio frequency identification transponder. While the name seems nonspecific and could refer to any kind of chip (I am personally quite fond of the chocolate variety), it actually refers to microchips. You don’t need a reason for your actions on Just Because Day (Aug 27), but please commemorate this day responsibly.Īug 15 is Check the Chip day. Beware the blight that (along with a mash- up of social and economic factors) caused the Great Hunger and enjoy some tastily-prepared tubers. Celebration of this day could take many forms indeed, but I shall tactfully abstain from further discussion. As this message too often goes unheeded, it is important that the masses unite in the quest for accountability from elected officials and secret agencies like “The Shop”.Īugust 5 is National Underwear Day. Please remember that with great power there must also come great responsibility. If you are overwhelmed by the specter of the social and public health ramifications of hordes of children returning to school this year, you can direct your attention (temporarily) to these unrelated observances:Īug 1 is Spider-Man Day. Welcome to the August edition of BLOG blog.
