RFID is used capture an individual objects, but it does not capture the inter-object relationship such as collocation and containment information. So, it leads to insufficient information about objects. RFID readings are inherently noisy with read a rate significantly leads to below 100 percent in actual deployments. This is largely due to sensitivity of radio frequency to environment factors such as metal objects and collisions among tags. So this leads to incomplete data. RFID can read excessive amount of large volume of data. However, the resulting data may encode significant amount of redundant information such as unchanged object locations.
