QR codes require a camera phone to scan them, which would be too slow compared to the almost immediate response time of scanning a barcode. 

@Dave you are absolutely right, moreover QR codes doesnt work properly if the surface is curved because device can't read the QR code if its on curved surface.

Although there are many advantages to using QR Codes there are also a few disadvantages to its use. One of the downfalls is you can't tell what it says, or even who put it there. "A spoofer can get you to click on a QR Code to a malicious link,"

QR codes have their purpose, but at this point I can’t see them being used as a replacement for standard barcode in the supply chain.  Believe it or not, many companies still don’t even use regular barcodes within their supply chain.  QR codes require a camera phone to scan them, which would be too slow compared to the almost immediate response time of scanning a barcode.  RFID would be a more practical choice in the supply chain vs QR codes, at least for now.

Electronics862, you are right and it has its own advantages. But the drawback is QR code can be implemented in batch wise only, itís not able to empose on each resistor or capacitor or IC. So the tracking is possible only by batch or lot wise.

With the help of QR code we can store more data about the product than RFID . We can reduce the size as the it's only binary/alphanumeric symbols. The readability is fast in improving the decoding rate. We can hope in the near future QR will be all over.

@Dorothea, Valid point. But don't you think the point about size also applies to RFID tags? In the end, perhaps the utility of these devices is more in the packaging than in the individual components. It's also likely supply chain people may seek to use QR codes only in finished goods because it may be easier to place the symbols on the packaging.

Unless QR codes are a lot smaller than I've seen, they are going to be too big for many electronic components, especially the rice grain sized passive components.  Marking the reel is not enough these days.

The codes can not only link to large amounts of data, but also triggers scripts on a web server linked to the scanner.  This has interesting possibilities for automated manufacturing and logistics.

@Jaden

You're right, it can provide a product verification to know which product is original, and the consumers can as well access the manufacturer's website by scanning the products QR code to learn more about the brand and its products.

"Average costs are difficult to determine, because the technology aims to solve unique company problems".

This is a great idea and a new venture for the electronics supply chain. If the costing issue is simplified.
