RFID fobs

What are RFID fobs and what are their uses?

RFID fobs are a part of a radio-frequency identification (RFID) system, which consists of two components: a microchip that stores data and an antenna that receives and transmits data. rfid fobs are usually shaped like key rings, which can be hung on a key chain or put in a pocket, for easy carrying and use.

RFID fobs have many uses, such as:

– Access control: RFID fobs can be used as credentials to open doors, by bringing them close to the access reader, which can unlock or lock the door. This method is more secure and convenient than traditional keys or passwords, and is suitable for places such as apartments, hotels, offices, etc.
– Identification: rfid fobs can store personal information, such as name, employee number, photo, etc., for identity verification or attendance management. For example, employees can use rfid fobs to sign in or sign out, recording their working hours.
– Public transportation: RFID fobs can be used as electronic tickets for buses, subways, trains, etc., by tapping them on the reader, which can pay the fare or enter or exit the station. This method is more convenient and eco-friendly than cash or paper tickets.
– Electronic payment: RFID fobs can be used as electronic wallets, storing a certain amount of money, for shopping or consumption. By bringing them close to the payment terminal, the transaction can be completed. This method is faster and safer than credit cards or mobile payments.

 How to copy RFID fob?

Sometimes, we may need to copy an RFID  fobs, for backup or sharing with others. There are several methods to copy an RFID  fobs:

– Using a professional duplicator: This is the simplest and most effective method, but also requires a certain cost. A duplicator is a device specially used for reading and writing rfid data, which can be purchased online or in physical stores. When using a duplicator, just place the original RFID key fobs in the reading area, and then place the blank RFID  fob in the writing area, press the button, and the copy is done.
– Using a mobile app: This is a cheaper and more convenient method, but also has some limitations. A mobile app is a software that uses the built-in NFC function of the phone to read and write rfid data, which can be downloaded from the app store. When using a mobile app, you need to make sure that both the original rfid key fob and the blank rfid key fob are 13.56MHz frequency and support NFC standard. Then, bring the original rfid key fob close to the back of the phone, open the app, select the read function, and wait for the data to appear on the screen. Next, bring the blank RFID  fob close to the back of the phone, select the write function, and wait for the data transfer to complete.
– Using a programmer: This is a more complex and advanced method, but also has more freedom and possibilities. A programmer is a hardware device that can be connected to a computer and controlled by programming software to read and write rfid data. When using a programmer, you need to have some programming knowledge and skills and understand the data format and protocol of different types and frequencies of rfid key fobs. Then connect the original RFID  fob to the programmer run the programming software select the read function and save the data to your computer. Next connect the blank RFID key fob to the programmer run the programming software select the write function and import the data into the blank key fob.

Do  RFID key fobs use RFID technology?

The answer is yes. rfid key fobs are a type of smart tags or cards that use radio-frequency identification (RFID) technology. RFID technology is a technology that uses radio waves to transmit data without contact or line of sight between objects.

RFID technology mainly consists of three parts:

– RFID tags: These are also known as rfid key fobs, cards, stickers, etc. They contain a micro antenna and a microchip that are activated by radio waves from an RFID reader device and read or write data from it.
– RFID readers: These are also known as scanners or interrogators. They are devices that generate radio waves and send them to RFID tags and receive data back from them.
– RFID software: This is also known as middleware or application software. It is software that processes and manages the data collected by RFID readers and connects them with other systems or databases.

History and evolution of RFID fobs

The origins of RFID technology date back to World War II when British developed a system called Identify Friend or Foe (IFF) which used radio waves to distinguish between friendly and enemy aircraft. Similar technology was later used by most powered aircrafts.

The first RFID device was invented by Russian physicist Leon Theremin in 1946 who created a listening device for Soviet Union which retransmitted incident radio waves with added audio information. Even though this device was not an identification tag it is considered as a predecessor of RFID because it was passive being energized by waves from an outside source.

The first patent for RFID was granted in 1973 to Mario Cardullo who proposed a passive transponder with memory. The first commercial use of RFID was in 1980s when Electronic Article Surveillance (EAS) systems were used to prevent theft in retail stores.

The development of RFID technology accelerated in 1990s with advances in microelectronics miniaturization wireless communication standards internet connectivity etc. Some of
the major applications of RFID in this period were:

– Animal identification: RFID microchips were implanted in livestock pets wildlife etc for tracking health management breeding etc.
– Toll collection: RFID tags were attached to vehicles for automatic payment of tolls on highways bridges tunnels etc.
– Supply chain management: RFID tags were attached to pallets cases items etc for tracking inventory logistics quality control etc.

The current trends of RFID technology include:

– Near field communication (NFC): This is a short-range wireless communication technology that enables two devices such as smartphones tablets etc to exchange data by bringing them close together. NFC can be used for mobile payment peer-to-peer sharing access control etc.
– Internet of things (IoT): This is a network of physical objects such as sensors actuators devices etc that are connected to each other and to internet through wireless communication technologies such as RFID NFC Bluetooth Wi-Fi etc. IoT can be used for smart home smart city smart health smart agriculture etc.
– RFID printing: This is a process of printing RFID tags directly on paper plastic fabric etc using inkjet laser thermal transfer etc technologies. RFID printing can reduce cost increase flexibility improve sustainability etc.
