What Is Microchipping?
Installing a glass encased transponder which has a unique
identification number under the skin of your puppy is generally
referred to as Microchipping.
Microchipping provides a permanent, relatively inexpensive form of
identification that cannot be lost, altered or intentionally
removed. The process is quick and painless and can help ensure a
Microchip containing a unique identification number is enclosed
within a tiny glass transponder about the size of a grain of rice.
This transponder is inserted by a needle into the scruff of the
dog's neck. Once inserted the transponder can be read by a
scanner. All the details assigned to the identification number are
recorded on the
Microchipping should only be performed by a Veterinary Surgeon or a
person trained to do so. At VIDEX Microchip Service all microchipping
is done by Rhoda Payne who has received full training in conjunction with a recognised
veterinary association and tutor from The Pet Chip Company and holds
a valid "pet-detect" Certificate of Competency.
What is a Microchip?
A microchip is the tiny computer chip that contains the unique ID
number assigned to the transponder. The microchip measures
approximately 1mm sq. Each unique ID number is encoded onto the
microchip during the manufacturing process by a laser that etches a
code onto the surface of the microchip prior to the transponder
assembly. The microchip is attached to an integrated circuit that
uses a coil of copper wire would around an iron (ferrite) core.
This functions as a tiny antenna to pick up the energy from the
scanner, and to send the encoded ID number from the microchip back
to the scanner. Between the copper coil and the microchip is a
capacitor used for tuning.
Videx puppies are microchipped using the AEG pet-detect®
system. The ID-162 microchip is assembled using Trovan-proprietary,
patented manufacturing technology. The Trovan product is
manufactured in a fully automated manufacturing process (i.e.
nothing is touched by human hands at any stage of the manufacturing
process). Other technologies require semi-manual assembly of
transponders, in certain competing brands, the transponder is placed
inside the needle by hand before packaging and sterilisation! The
Trovan/AEG patented direct-bonding method uses gold bumps, NOT lead
solder. The "pet-detect®" transponder has no lead soldering
joints. Lead is a toxic substance. All ISO microchips conform to
the ISO Standard 11785. ISO microchips use the protocol set out in
Standard 11785 and is the preferred microchip protocol for the UK
and many other European countries.
What are Transponders and how do they work?
A transponder is simply the tiny electronic device encapsulated in
biocompatible glass used to store an identification number. The
size of the "pet-detect®" transponder is 2.12mm x 11.5mm and is
often compared in size to an uncooked grain of rice.
Most people are familiar with laser scanning of bar codes on
groceries and household goods go identify them at the cash till.
There are two principal differences between electronic
identification (EID) and bar code technology. Electronic
identification uses a common low-power signal to read an ID number
stored in a tiny electronic circuit, the microchip. Bar codes use
laser light to read the label. Electronic identification is also
referred to as "radio frequency identification" or RFID. Low
frequency radio waves, unlike laser light, can penetrate all solid
objects except those made of metal. Therefore, use of electronic
identification allows the tiny device carrying the number to be
injected into an animal where it resides permanently. The
transponder is made of inert material so it won't be rejected by
your dog's body. Once implanted, transponders cannot be lost or
altered, or become worn like an external collar tag. The
transponder which is really the outer casing (encapsulation) of the
microchip but is often referred to as the microchip itself.
The transponder is packaged within a sterilised needle, the needle
cartridge containing the transponder is placed on the implant gun
ready for implantation. It's logical that a thin, extremely sharp
needle is kinder to the dog. The needles we use at Videx have a
unique 'thin-walled' design. As a result, the outer diameter which
is what the animal experiences during implantation, is significantly
smaller. It is in fact more like a conventional 13-guage needle
than the standard 12-guage needles used by many other brands.
Minimising the outside diameter of the needle is important in animal
applications because it decreases the chance of haematoma and is
less likely to cause discomfort. Also the needles we use, unlike
other brands, have a double bevel, therefore, the needle neatly
incises the skin rather than puncturing it. The opening heals more
easily and the transponder is less likely to be extruded.
read the ID number of the transponder you require a scanner. Most
scanners generate an excitation signal in the low frequency radio
band. The power of the scanner's signal is less than one
one-thousandth of a watt (one milli-watt). When the scanner is
passed over the implant site the scanner reads the ID number of the
transponder as a radio signal, which is then decoded and displayed
on the scanner as a 15-digit number.
The "pet-detect®" transponder uses the ISO protocol (FDX-B) and can
be read by all scanners.
