Radio Frequency Identification
Radio Frequency Identification is now commonly used for automatic identification of goods - AIDC (Automatic Identification and Data Capture).
Recognition of marked objects is carried out using a radio signal. They are marked with RFID tags (also called transponders) - when it is in the electromagnetic field generated by the RFID reader, the identification number is read and recorded.
UHF RFID systems
A computer system (with a database) and two types of radio identification devices: RFID readers (transceivers) and tags.
HF technology
High frequency (HF) is the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz.
Barcodes
Graphical representation of information through a combination of dark & light elements, determined according to symbol.
