Radio Frequency Identification (RFID)

The term radiofrequency identifier is used to automatically identify an object that wirelessly identifies an object using radio waves (in the form of a unique serial number).

Abbreviation for RFID as RFID is a Dedicated Short Term Communication (DSRC) technology. It is very similar to barcode identification systems, but there is a big difference. RFID does not require visibility, but bar code scanning is mandatory.

RFID technologies are grouped by more generic Auto ID (ID) technologies. Existing identification systems are not enough for today's use as they have low storage capacity and another fact that they can not be reprogrammed.

A feasible solution is to insert data into silicon chips and to reduce data transfer between the data transfer device and the reader. The power needed to operate the data transfer device has been moved from the reader through the less advanced technology. All of these lead to the development of RFID devices In RFID, the RFID tag containing labeled data in the object generates a signal containing the correct information that the RFID reader can read and which can be read by the RFID reader. information to a processor for processing information received for that application.

With RFID, electromagnetic or electrostatic coupling transmits signals in the RF (radio frequency) part of the electromagnetic spectrum. The RFID system consists of an antenna and a transceiver that reads the radio frequency and transmits information to a processing device (reader) and a transponder or RF member that contains the RF circuits and the information to be transmitted. The antenna allows the integrated circuit to transmit information to the reader that converts radio frequency waves reflected from the RFID tag to digital information that can be passed on to customers in which the data can be analyzed.

Data processing subsystem

Transponder or RF tag label may be active or passive. While active tags are on a chip, passive tags use the energy generated by the RFID reader magnetic fields. Thus, passive labels are cheaper but there is limitation that they are limited (RFID frequencies: RFID systems differentiate according to frequency range.) Various ranges are low frequencies (LF: 125 – 134.2 kHz and 140 [14859 kHz] high frequency (HF: RFID, Label, Transponder, Radio, Frequency, Identification

Ultra-High Frequency RFID Systems More Than 13.56 MHz and Ultra-High Frequency (UHF: 850 MHz – 950 MHz and 2.4 GHz – 2.5 GH) They offer a 90-foot transmission range, but in the 2.4 GHz range the wavelength is absorbed by water, which also includes the human body that limits its use.

Standards The RFID standards used in RFID were primarily emphasized in the following areas [19659002] Air Interface Protocol for the communication of labels and readers

Data content data in labels

Conformity – Examine whether products meet standards

EPC standards for labels:

Class 1 is a simple, passive, read-only

Class 0: read-only tag programmed at the time of microchip creation

Different RFID applications: RFID has been recently applied: – Identification of persons, Identification of the person's place of residence, Identification of animals / pet, Food production control, Vehicle fleet monitoring / monitoring, Toxic waste management, Valuable objects, Insurance identification, Device management,

RFID Security: Basic data protection considerations related to the RFID system are the ability of unauthorized persons to pass unauthorized access. These are ways to use RFIDs to circumvent personal data protection. Hide RFID tags hidden from the eyes and track stealth or identify profiles provided by RFID, identify consumer patterns and behaviors or hijack readers to track stealth and gain personal information.

Because of these reasons, some attempts are made to maintain privacy and reduce the disadvantages mentioned above

RSA Blocker Tags: A reader trying to read labels without proper authority, so interfering with the reader to believe that many labels is in the vicinity

Kill Switches: The consumer has the opportunity to disable the RFID tag to avoid stealth tracking and profiling
