For the past week, i've learnt about RFID which stands for Radio Frequency Identification which uses radio frequency waves to transfer a unique identification from a tag to a reader.
Three basic components in the RFID system consists of a RFID tag, a RFID reader, and a predefined for the information.
The three essential elements of a RFID tag consists of an antenna, integrated circuit, and memory.
Mr Cheng also showed us some of them and we took a few snapsnots of it.


Our surroundings are full of the RFID technology...
Even in in the library!
