QR codes can be used on assembly lines in many ways, including:
‍

1. Linking products with their associated data, for example, serial numbers, production dates, and other information. 
2. Controlling the flow of the assembly line by directing workers to specific tasks or processes for each product. 
3. Tracking production time and quality assurance data, making it easier to monitor quality control on the assembly line.
4. Quickly and accurately identifying a product on an assembly line.

Yes, QR codes are perfect for tracking inventory. QR codes were actually originally created for the manufacturing industry to track car parts in warehouses. Here are some ways they can be used:
‍

1. Track the exact location of inventory items in storage.
2. Track how much inventory is available at any given time
3. Identify which products are in need of reordering. 
4. Access product information such as price, description, and vendor information. 
5. Securely capture data from suppliers or customers. 
6. Integrate the QR code with inventory management software to efficiently manage the entire inventory process from end-to-end.

QR codes make factories safer by streamlining many processes and providing access to safety information. Some examples of how QR codes can make factories safer include:
‍

1. Access to important safety information and protocols such as safety instructions, emergency procedures, and other relevant information to workers.
2. Providing an easy way to keep safety information updated.
3. Tracking and monitoring equipment maintenance and inspections.

By providing workers with easy access to safety information and tracking equipment maintenance, QR codes can help prevent accidents and improve overall safety in the factory.

Using QR codes in logistics has been used for a long time, dating back to their invention in the car manufacturing industry. Here are some ways QR codes are used in logistics:|
‍

1. At shipping and receiving to quickly track shipments
2. Tracking products in transit
3. Storing documents and other records related to shipping and inventory management 
4. Automating the process of documenting product movement with QR code
5. Updating inventory levels through scanning of QR codes on outgoing items
6. Tracking high-value items in transit with unique, secure QR codes

QR codes are used in supply chain management in a myriad of ways, such as:
‍

1. Tracking the movement of goods throughout the supply chain
2. Keeping track of inventory levels, locations, and other related data. 
3. Identifying and verifying products as they move through the supply chain. 
4. Tracing products from source to shelf, allowing companies to ensure product quality and safety standards.
5. Authenticating authorized personnel for security purposes 
6. Collecting payments and transactions within their supply chain network.

QR codes simplify the business side of manufacturing through streamlining many of the business processes that manufacturers perform. Examples include:
‍

1. Streamlining the process of tracking inventory and materials, reducing the amount of time spent manually entering data. 
2. Identifying the supply chain of products, including who made a product, when it was created, and where it is located.
3. Improving the accuracy and speed of invoices and purchase orders. 
4. Providing real-time tracking data on parts and products. 
5. Simplifying maintenance schedules with detailed instructions on how to properly maintain machinery.
