Barcode and RFID, A one-two punch when it comes to sequencing

UHFRFIDAll too often I read about RFID replacing barcode as an ID technology. No doubt, there are cases where RFID is used to replace a barcode system due to a harsh environment or there is a need to “de-centralize” information etc., but more often than not I see both barcode and RFID being used together to address an application. It doesn’t have to be one or the other.

One application where the two live in harmony is sequencing. Sequencing is referred to by many different names and acronyms and is synonymous with automotive assembly plants and their tier suppliers. In a nutshell, the goal is to deliver the exact number of components in the exact order they will be used. When this is done efficiently the result is a WIN-WIN-WIN. A win for the supplier because they decrease the amount of in-process inventory and carrying costs; A win for the manufacturer because they maximize their floor space and spend less time hunting parts and components to complete a build; And a win for the consumer because they get their new car faster.

As one can imagine there is a great deal of communication and data sharing that must take place in order for this to operate smoothly. This is where the one-two punch of RFID and barcode come into play. The most common method is to identify the parts with barcodes and write the barcode data to the RFID tag which is fixed to the carrier. The information on the RFID tag identifies the carrier and identifies the components on the carrier. Rather than explain how this works, it makes more sense to look at a real-life example of how a major automotive supplier achieved their sequencing goals by using the one-two punch.

Asset Tracking – Top 10

The goal of plant-based asset tracking is to reduce non-productive time and asset losses, while increasing overall productivity and utilization by accurately tracking assets. Bar code and RFID technologies track changes to an asset’s location, condition, conformity status, and availability.

Balluff has been in this business for over 25 years. Based on that experience, we have compiled the top 10 list of commonly tracked plant-based assets:

1. Dunnage containers
2. Machine tools
3. Plant-floor Equipment
4. Stamping dies
5. Torque Wrenches
6. Plastic Molds
7. Storage tanks and vessels
8. IT equipment
9. Automated Guided Vehicle (AGV)
10. Modular automation sub-systems
