FDX-B microchip RFID pet chip ISO pet microchip

Electronic identification microchip is also referred to as “radio frequency identification tag”, or RFID tag. Use the  RFID technology allows a microchip programmed with a unique identification number, around the size of a grain of rice, to be implanted in an animal. they're without power until the microchip scanner sends a signal.

each microchip scanner contains a coil antenna that sends a signal to the microchip when the scanner gets close enough.

The RFID scanner sent radio waves to give the microchip enough power to transmit its 15-digit number back to the scanner. Once the scanner has picked up this signal from the microchip, decoded it, and displayed the number, the microchip then remains dormant until a scanner is active again.

As the microchip is passive and is only powered when the scanner is passed over the area, it lasts for the lifetime of the animal. Microchips themselves are only programmed with the unique 15-digit number, they do not contain any pet or owner details. These details are stored alongside the microchip number on a microchip database. Once the animal is scanned and the microchip number obtained, an authorized person must then contact the database in order to obtain the owner/keeper details.

The  FDX-B ISO Standards pet microchip compliant series features RFID microchip transponders with factory pre-programmed 15-digit ID codes. The first three numbers denote the manufacturer. There are then a series of noughts and then 6, 7, or 8 digits.

An iso 11784 microchip is an electronic transponder encapsulated in biocompatible glass. The size of the FDX-B microchip is Regular 2.12mm x 11.5mm and Mini 1.4mm x 8mm, both fall under the category of a ‘microchip transponder’. They can be referred to by many names including microchips, RFID PET chips, PIT tags, transponders, and RFID scanners.

An ISO 11784 microchip is a biocompatible electronic transponder encased in glass. The FDX-B microchip is available in two sizes: Regular 2.12mm x 11.5mm and Mini 1.4mm x 8mm, both of which are classified as "microchip transponders." Microchips, RFID PET chips, PIT tags, transponders, and RFID scanners are some of the terms used to describe them.

What is FDX-B  microchip?

FDX-B Animal Identification Protocol description.

FDX-B protocol is a common format used in transponders in applications requiring animal identification. It fully complies with the ISO 11784 & 11785 standards.  The ISO 11784 & 11785 microchip including  FDX-B (full-duplex), and HDX (half-duplex).  Here we will talk about the FDX-B protocol microchip.

 The frequency and modulation of FDX-B microchip.

FDX-B protocol-based transponders are defined to operate in the 134.2kHz band and employ a biphase encoding scheme to transmit their information. The data bit rate used is always fc/32.

Biphase encoding schemes modulate the RF field so that there is a transition at the beginning of each bit

boundary.  A logic 0 state has a transition in the middle of the bit period, while a logic 1 state has no transition

during the entire bit period. For FDX-B 1 bit length corresponds to 32 cycles of the activated field of the reader

FDX-B data structure.

FDX-B protocol based transponders carry 128 bits of data. The structure of this data consists of:

11 header bits (10000000000)  Lsb bit first.

64 identification bits with 8 control bits.

16 bits of CRC with 2 control bits.

24 bits of extended data with 3 control bits.

The control bits are simple logic 1 bits that appear after every 8 bits. They are used to differentiate the 11 bit header from the remaining data.
