Recently, passive Radio Frequency Identification (RFID) systems have received an exponential amount of attention as researchers have worked tirelessly to implement a stable and reliable system. Unfortunately, despite vast improvements in the quality of RFID technology, a significant amount of erroneous data is still captured in the system. Currently, the(More)
Since the emergence of Radio Frequency Identification technology (RFID), the community has been promised a cost effective and efficient means of identifying and tracking large sums of items with relative ease. Unfortunately, due to the unreliable nature of the passive architecture, the RFID revolution has been reduced to a fraction of its intended audience(More)
The use of Barcodes and Radio Frequency Identification (RFID) technology has become a ubiquitous means of inventory and asset tracking. When considering the application of monitoring people in an enclosed environment, for example in a classroom or an examination setting, previously employed RFID-enabled solutions have yielded high costs and poor user(More)
Within databases employed in various commercial sectors, anomalies continue to persist and hinder the overall integrity of data. Typically, Duplicate, Wrong and Missed observations of spatial-temporal data causes the user to be not able to accurately utilise recorded information.
