What is RFID? And how does it work?
RFID (pronounced "erefajdi") stands for Radio Frequency IDentification. Meaning: radio frequency identification. This technology is a great solution and not complicated at all. Radio waves transmit data.
How does the plane get here? The spread of RFID solution is linked to World War II. The British used this method of identification to distinguish enemy planes from their own. Which is not a disadvantage in warfare. Just like other clever and ingenious technological solutions, RFID grew out of the military industry. And from there began its soaring. It serves the hustle and bustle of everyday life and business in many ways.
RFID belongs to smart cards. A smart card contains an embedded chip (integrated circuit), which can be passive, i.e. only the chip number can be read, or it can be active, which allows data storage and/or a programmable microcontroller. It works with the help of a smart card system, which usually includes the card and card reader.
RF identification technology is used for many cards. Data is stored on a chip embedded in the card. The chip contains an embedded secure microprocessor or equivalent solution and internal memory. The antenna is embedded in the plastic body of the card. RFID technology is used for communication between the card and the reader. The card should be held close to the reader so that the card and reader can communicate via embedded antennas using radio frequencies.
When the card is inserted into the electromagnetic field of the reader, the chip in the card turns on. As soon as the chip is turned on, a wireless communication protocol is initiated and established between the card and the reader for data transfer.
Below is a summary of the sequence of events that occur when the card is brought to the card reader.
⦁ Energy is transferred to the card, which feeds the chip inside the card
⦁ Transfer of data from reader to card
⦁ Transfer of data from card to reader
RFID cards are safe because not every RFID reader can read every card. Encryption keys are used for security, and data can only be programmed into the smart card's memory by authorized persons.
So, RFID cards offer an easy-to-use and secure way of communication for identification. RFID smart cards are commonly used in applications that require privacy and fast, secure transactions. Examples include ID cards, fare payment cards, credit and debit cards, etc.
How does RFID technology serve your business?
The possibility of connecting RFID technology with plastic cards enables fast digital communication between the card and the computing devices processing the card data. The new cards opened up new perspectives for companies, institutions and businesses.
The range of applications of RFID cards is terribly wide.Today, reading systems can read several cards simultaneously, and thanks to the structure of the RFID chip, one card can perform several functions (access control, payment) simultaneously.
Its most well-known and frequently used uses are: ID cards, access cards, key cards, but it is also used in public transport, e.g. as a season ticket, in cashless payment systems for events, for identification tasks of fitness studios, spas, swimming pools. In the financial and payments sector, identity management, other areas of logistics, healthcare, mobile communications.
The smart use of all these options gives businesses a significant competitive advantage.
