Ever since the RFID technology emerged, it has become an integral part in different industries. A problem arises when several tags or readers are being detected which results in collision on the communication channel. Collision in RFID occurs when tags are simultaneously detected and the data signals are overlapping. This thesis paper discussed how a low frequency (125 kHz) Radio Frequency Identification (RFID) Reader manages to detect multiple tags simultaneously without being costly. The study aimed to avoid collision among the tags using digital signal preparation techniques than a pre-emptive method such as using specialized RFID tags. The software tool used in the study is Matrix Laboratory (Matlab) that is used in the information retrieval and data separation tags. GUI and histogram feature of Matlab was also used in this study to show data and results effectively.
