The studies of tags detection performances for different tags type in RFIWS system

In the past, walking sticks and dogs have been of great assistance to the blind. However, the conventional assistive methods are limited in providing accurate path directions with additional information such as the road names and nearby facilities. Hence, a Radio-Frequency Identification Walking Stick (RFIWS) system was developed as an enhancement to the conventional design. The system utilizes an Ultra-High Frequency (UHF) reader, tag and an antenna In market place, many RFID tags type was available. The different tags type have a different tag detection performance such as a maximum tag detection length and strength. Therefore, the studies of tags detection performances for different tags type conducted. Two experimental test has done namely tag detection pattern with maximum detection length and percentage of average returning signals. Nine different tag type has been used in this test. Results show that the Twister tag managed to achieve the best performance with the largest detection pattern, longest maximum detection length, and highest average received signals.
