Why do QR codes generated in two different online services for the same plain text differ?
Mind that QR codes may use 4 different levels of error correction, labeled L, M, Q and H, respectively. Also, there is a process called masking, with the intention to increase the robustness of the reading process by distributing the black and white pixels over the image. There are also a number of masking patterns available, which can produce a valid QR code, but with different results. Read the specification for more info on those.That being said, given a generator with the same settings, the output should always be the same, which is what your original question was about. Now, comparing two different generators might result in observing two different images due to the effects mentioned above.Why Don't Duplicate QR Codes Look The Same?
How do I generate a large batch of QR codes?
If you want to generate a large number of QR Codes, you have the following two options:1. Batch GenerationBatch Generation allows you to create thousands of unique QR Codes in a short period of time. Most QR Code Generators allow you to create one QR Code at a time. But with Batch Generation, you can share data in a spreadsheet and get the QR Code images. It usually takes around 24-48 hours. This is a good option if you need QR Codes in the range of 100-100,000. For details, see: Bulk QR Code Generator2. QR Code APIYou can also integrate a QR Code API into your application and automate the process of generating a QR Code as and when required. This is a much better option than Batch Generation if you need between 100-1Million QR Codes per month. For details, see QR Code API(Full Disclosure: I am a cofounder of Scanova).
What is the exact difference between QR code and Augmented reality ?
Both QR codes and augmented reality are forms of computer vision. The main difference is that QR codes are typically scanned as an image with a QR code application. It's then decoded and leads to some action, like opening up a website. Augmented reality is a bit more fluid whereby different objects, signs, words, etc. can be scanned as a real-time video or image and then some type of digital information is overlaid on top of the scene your are viewing within the application.
