发明名称 RFID time tracking
摘要 An improved method of keeping track of time is provided, and specifically an improved method of tracking the amount of time spent by an individual working on a project. The person scans an RFID tag associated with a file using an RFID reader, and a software program begins counting time and associating it with the matter with which the file is related. When the person scans the RFID tag again, the time is stopped, and the elapsed time is billed to a client in regard to the matter associated with the file.
