Introduction
A microchip is a small electronic device that can be implanted in pets like dogs and cats. The microchip contains a unique identification number that can be read by a scanner. Microchipping pets provides permanent identification that cannot get lost or damaged like a collar or tag can.
Microchipping has become a popular way to identify pets and reunite lost dogs with their owners. Veterinarians and shelters can quickly scan a stray pet for a microchip and access the owner’s contact information to return the pet home. Because the microchips last for the pet’s lifetime, they provide a reliable long-term form of identification compared to collars and tags.
There are two main technologies used for pet microchips today – NFC (Near Field Communication) and RFID (Radio Frequency Identification). While they work similarly, there are some key differences between RFID and NFC microchips that impact features like data storage capacity and scanning compatibility. Understanding the differences can help owners make the right choice for their pet.
NFC (Near Field Communication) Technology
NFC, which stands for Near Field Communication, is a short-range wireless technology that allows devices to communicate when they are brought within close proximity of each other. NFC enables contactless communication between devices that are within 4cm or less of one another.
NFC works by allowing two NFC-compatible devices to establish radio communication when brought close together. One device acts as an NFC reader while the other acts as an NFC tag. The NFC reader generates a radio frequency that provides power to the passive NFC tag, which then transmits data back to the reader. This allows small amounts of data to be exchanged wirelessly over distances of just a few centimeters.
Some of the key advantages of NFC technology include:
- Simple and intuitive to use – just bring devices close together
- Secure – NFC transmissions are encrypted
- Fast data transfer speeds
- Low power consumption
- Compatible with existing contactless smart card infrastructure
NFC is commonly used in contactless payment systems like Apple Pay and Google Pay, as well as smart public transportation cards, access control systems, and information sharing applications.
RFID Technology
RFID stands for Radio Frequency Identification. It is a technology that uses radio waves to transfer data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking. Here’s how it works:
The tag contains a tiny RFID chip and antenna. The chip stores a unique identification code and sometimes additional data. When an RFID reader emits radio waves at a specific frequency, the tag detects the signal. The antenna enables the microchip to transmit the ID code and data back to the reader via radio waves. The reader converts the radio waves into digital information that can then be passed on to computers for tracking and analysis.
RFID tags come in various forms, but are commonly stickers or cards containing an embedded chip and antenna. They are extremely small, lightweight, and unobtrusive. The tags have no battery – instead, they are powered by the radio waves from the RFID reader. This allows RFID technology to be highly versatile and usable in a wide variety of identification applications.
Overall, RFID provides a wireless way of transmitting identification and other data using radio waves. The tag requires no power source, and the information can be read at a distance without a direct line of sight to the reader. This makes RFID technology highly useful for supply chain management, inventory control, asset tracking, and more.
Microchip frequencies
Microchips operate on different radio frequencies depending on the technology used and the organization issuing the microchip. Here are some of the main frequencies used for pet microchips:
- 125 kHz – One of the original frequencies used for microchips. Still common but being phased out in some countries.
- 128 kHz – Used by some microchip manufacturers like Datamars.
- 134.2 kHz – Common frequency issued by organizations like the American Kennel Club and HomeAgain.
- 900 MHz – Used by bottlepal pet tags, which contain both a microchip and Bluetooth tracker.
- 13.56 MHz – The near field communication (NFC) frequency also used by contactless payments and some building access cards.
The frequency impacts factors like read range, data storage capacity, and compatibility with different scanners. Lower frequencies like 125-134 kHz have longer read ranges, while higher frequencies like 13.56 MHz offer more storage space but shorter scanning distance. International standards help ensure compatibility across frequencies.
Microchip data storage
Microchips contain a small amount of data which provides basic identifying information. This typically includes an identification number unique to the microchip, the microchip manufacturer, and contact information for whoever registered the pet with the microchip company. The exact data fields that can be stored vary between microchip manufacturers.
The main purpose of the data on a microchip is to provide a way to identify the pet if it gets lost. By scanning the microchip, the identification number can be looked up in the microchip company’s database to find the registered owner’s contact information. Some microchips have very limited data storage – just enough for the ID and manufacturer codes. Other microchips have more memory and can store additional owner information such as name, address, phone numbers, and email.
It’s important to note that microchips themselves do not actively track or transmit the pet’s location. They simply serve as an identification tag if the pet is found. All location tracking requires additional external technology beyond just the implanted microchip.
Microchip scanning
Microchips are scanned using handheld RFID scanners. The scanner emits a low-energy radio wave that activates the dormant microchip, causing it to transmit the pet’s ID number back to the scanner.
The scanner must be passed over the area where the microchip is implanted, usually the back of the neck/shoulder blades in dogs and between the shoulder blades in cats. The microchip has an effective scanning range of a few inches or less. When the scanner successfully reads the microchip, the pet owner’s contact information associated with that ID number will be displayed on the scanner.
Scanners work similarly to barcode scanners. The microchip ID number is transmitted back to the scanner in an encrypted form. The scanner decrypts the ID and uses it to reference the registration database, retrieving the pet’s information to display to the operator.
Most universal scanners are able to read both ISO and non-ISO microchips. Some scanners have the ability to differentiate between microchip formats and frequencies, displaying this information to the operator to facilitate locating missing pets.
Microchip standards
There are a few main microchip standards used for pet identification:
-
ISO 11784 and 11785 – These International Organization for Standardization (ISO) standards define the technology used for radio-frequency identification (RFID) of animals. They specify things like the radio frequency, data structure, and communication protocols.
-
FDX-B – This is a common microchip standard that operates at a frequency of 134.2 kHz and can be read from up to 10 cm away. It conforms to the ISO 11784/11785 standards.
-
HDX – This higher-power microchip operates at a frequency of 134.2 kHz as well and can be read from up to 50 cm away. It also conforms to ISO 11784/11785.
So in summary, microchips conform to international standards that define the technology, and then there are particular standards like FDX-B and HDX that operate at a specific radio frequency and have defined reading distances.
NFC vs RFID for Microchips
When it comes to microchip technology for pets, the two main options are NFC (Near Field Communication) and RFID (Radio Frequency Identification). While both use radio waves to transmit data, there are some key differences between the two technologies:
Frequencies: NFC uses a frequency of 13.56 MHz, while RFID typically uses lower frequencies like 125 kHz or 134 kHz. The lower frequencies allow RFID tags to be read from longer distances compared to NFC.
Read Range: The max read range for NFC is about 4 inches, while RFID can reach up to a few feet. This makes RFID better suited for scanning pets from a short distance.
Data Storage: NFC chips can store a few kilobytes of data, while RFID chips have less storage in the range of 128 bytes. This allows NFC chips to hold more identifying information about pets.
Power Source: NFC requires an external power source from the reader device, while passive RFID tags are powered by the electromagnetic signal from the scanner. This gives RFID better versatility.
Standardization: NFC is a more mature, standardized technology that is widely used in smartphones and other devices. RFID standards are still evolving when it comes to pet microchips.
In summary, RFID tends to be favored for pet microchips due to its longer read range, smaller size, and no need for an onboard power source. But NFC offers greater data storage and standardization. When choosing between the two technologies, pet owners should consider the scanning applications and data requirements.
Benefits of microchipping
There are many important benefits to microchipping your dog. Here are some of the main reasons pet owners choose to microchip their furry friends:
Permanent identification. A microchip provides a permanent way to identify your pet. Unlike collars and tags which can be removed or lost, a microchip is implanted under your dog’s skin and remains there for life.
Reunification. If your dog ever becomes lost or separated from you, your contact information in the microchip registry allows animal shelters and veterinarians to identify your pet and contact you quickly for reunification. This greatly improves the chances your lost pet will be returned home.
Safety precaution. Accidents happen, and dogs can slip out doors or escape from yards. Microchipping provides an essential backup in case your dog ever becomes lost unexpectedly. You’ll have peace of mind knowing there is permanent ID to bring your pet home.
Legal requirements. An increasing number of cities and regions legally require pets to be microchipped and registered. Microchipping your dog ensures you’ll meet any local regulations.
Travel requirements. Many airlines and travel destinations require proof of microchipping before allowing pets. Getting your dog microchipped makes travel with your pet easier.
Veterinary benefits. Microchips provide veterinarians immediate access to your contact info and your dog’s health records in case of a medical emergency.
Conclusion
In summary, while NFC and RFID technologies have similarities, RFID is the technology used for microchipping dogs and other pets. RFID microchips operate at a lower frequency than NFC and can store a unique ID number that links to a pet registration database. This allows lost pets to be identified and reunited with their owners when the microchip is scanned at a vet clinic or shelter.
Microchipping pets provides numerous benefits. It is a safe and permanent form of identification that cannot fall off or be altered. The process is quick, simple and relatively painless for insertion. Scanners to read microchips are widely available. Overall, microchipping remains the best way to improve the chances of reuniting lost or stolen companion animals with their families.
For pet owners, the recommendation is to strongly consider getting your pet microchipped. The minimal risks and costs are far outweighed by the potential to be reunited with a cherished family member. Consult your veterinarian to get your pet microchipped and registered in a database.
