1. A method of tracking a tagged object, comprising:
receiving, using a first processor, a first video of an object tagged with a radio frequency identification tag and first metadata read from the radio frequency identification tag;
storing, using the first processor and to a first storage device, the first metadata in association with the first video; and
writing, using the first processor, second metadata to the radio frequency identification tag that overwrites the first metadata responsive to the receiving;
receiving, by a second processor, a second video of the object tagged with the radio frequency identification tag and the second metadata read from the radio frequency identification tag;
storing, using the second processor and to a second storage device separate from the first storage device, the second metadata in association with the second video; and
writing, using the second processor, third metadata to the radio frequency identification tag that overwrites the second metadata.
