manufacturing control and data collection systems
For any manufacturing control system a kind of drawback of an excessive dependence on up-to-date information about the products and other elements which move within the system is essential.

Radio-frequency identification
• Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.
• Tags • Antenna • Reader
Bar code in compare to RFID in manufacturing control context
• When a part is complex, it may lack a convenient and scan able location for bar codes. RFID tags can be placed anywhere on the part, and scanned from any orientation.
• Unlike bar codes, RFID tags can store data for continuous production updates.
• Unlike bar codes, RFID tags are unaffected by the dust and grime common to industrial environments.
• RFID tags can provide monitoring of the arrival, continuous presence, and departure of specific parts to/from a cell, allowing for better management of routes and locations in the assembly environment.
