RFID Key Fob are RFID tags designed to take the shape of key fobs. They comprise a microchip and an antenna. The chip stores data while the antenna receives and transmits radio waves that aid in data exchange.
The RFID key fob can house low frequency, high frequency, or ultra-high frequency tags. When choosing your ideal RFID key fob, you should ensure that you only pick the right frequency for the best results.
RFID Key Fobs are widely used in control, attendance control, identification, logistics, industrial automation, ticketing, casino tokens, membership, public transportation, electronic payment, swimming pools, and laundries.

Access control is the main purpose of RFID key fobs. Their microchips are programmed with a unique identifier that can be read by an RFID reader.
When the RFID reader scans the tag, it compares the identifier with a list of authorized users. If the user is on the list, they will be granted access. If not, they will be denied access.
RFID key fobs can also be used for pet management. The key fob can be embedded with a chip containing a product code.
When scanned, the reader captures the code and sends it to an RFID software system. This information is then used for tracking and pet identification.
RFID key fobs can be used to manage events. Their unique identifiers can be used to track guest attendance and can be used for event payment.
This information can be used to plan future events or to evaluate the success of past events.
ABS RFID key fob it consists of ABS shell, chip and antenna. It is widely used in RFID management applications, such as access control, identification systems, etc.
ABS RFID key fobs are available on request in the most common 125 kHz, 13.56 MHz 916MHz RFID chip types. The chip code can be laser engraved or painted on one side, which saves time in checking the ID code of each key fob holder, thus greatly improving management efficiency.
PU Leather RFID Key Fob It consists of leather cased RFID cards. It is widely used in RFID management applications, such as access control, identification systems, etc.
PU Leather RFID Key Fob is high-end and available in the most common 125 kHz, 13.56 MHz 915MHz RFID chip types upon request.

125KHz RFID low frequency key fob has minimal interference with metal and can be customized with logo and serial code. Mainly used for access control and automatic identification.
13.56MHz RFID Keyfob is suitable for access control applications, event management and applications where keys need to be tracked. It is waterproof, the keyfob tag has stable response in very low or high temperature environments and is NFC compatible.
RFID UHF Keyfobs can be customized with logos, serial codes or EPC laserized. They are used for access control and automatic identification.
RFID tags cannot be used alone, so you need to make sure you have your own existing system or that you are a system integrator so that you can purchase your own RFID tags.
Chip is the core of RFID can store and exchange data, for the beginning of the system design will choose a good chip model, different chip features and prices are different, so you need to determine your own system to use the chip model.
If you do not know your own chip model, you can send us a sample of your hand to help you test the chip model.
The price is different for different materials and sizes, so choose the right material and size for you based on cost control.
We can customize the logo, print UID, Encoding data etc. for RFID Keyfob.

A key fob contains a short-range radio transmitter/radio frequency identification (RFID) chip and antenna. It uses radio frequencies to send a distinct coded signal to a receiver unit in the device. This receiver also contains an RFID tag, which is some form of stored information. Read more.
RFID keyfob uses RFID technology, while RFID is included NFC. What is difference between NFC and RFID? Pls read this blog.
RFID Keyfob can be copied or not, depending on the specific chip type used and the encryption method, like the read-only TK4100 chip is the most easily copied. High-frequency M1 chip encryption method is also easy to be copied if it is simple.
Not necessarily, it depends on whether the chip of your card is RFID or NFC. The NFC chip can use the mobile phone as an RFID card.
RFID keyfob usually small size, low frequency and high frequency reading distance is generally in 0-5cm, more than the frequency of the reading distance in 0-2m.
The passive RFID keyfob itself has no power and is powered by the RF energy transmitted by the RFID reader/antenna. The signals sent by the reader and antenna are used to power the RFID Keyfob and reflect the energy back to the reader.
Since some chips are rewritable, hackers can even delete or replace RFID information with their own data. Most of the chips are highly encrypted and are not replicable by hackers.
The RFID Keyfob can be used with a lanyard, Velcro or other mechanism to make the Keyfob easy to carry by the person being tracked. Once the person has the tag, it can be tracked through a facility, field, tool yard, or wherever needed.
Almost all automobiles manufactured since 1995 have had an RFID transponder embedded in the plastic housing surrounding their key grip. These 13.56 MHz passive transponders communicate with an RFID reader in the steering column.
Metal and water have the greatest radio frequency interference. You can put the RFID Keyfob in a metal box. There are many shielded wallets on the Internet. There is a layer of metal fabric inside the shielded card sleeve.
