1. What is the technology behind Taggun?
A: Taggun takes advantage of Google Vision API (the most robust OCR text extraction in the market. Yes, I've tested a few). And I build and improve algorithm to extract metadata like purchase amount, tax amount, date, merchant name and etc... from the extracted text. The platform is built on node.js and is hosted on AWS with Docker for speed and scale. See the full stack here.

2. Does Taggun supports receipts from countries other than US and New Zealand?
A: Yes. Taggun can support 56 languages. Caveats: When entering a new other-than-English market, extraction and accuracy rate will be lower. Rest assured, the accuracy rate will improve vastly once I have enough data to train the algorithm.

3. What about security with Taggun?
A: All images are encrypted when with AES256 when in transit and at rest. Taggun does not store any sensitive personally identifiable information (PII). Any non-sensitive information such as IP Address will have standard security safeguards and controls. By the way, there will also be an option available to opt-out storage of any kind.

4. So, what is Taggun? Why do we need this when Google Vision, Microsoft Cognitive Services and other OCR providers already solved the problem?
A: For simple image-to-text OCR scan, Google Vision provides the best OCR results in the market (I tested). But the OCR'ed text are still not perfect. Take for example, "TOTAL $14.53" can be extracted as "T0T AL S14, 53" Taggun does the hardwork to convert these half-garbage text into useful metadata like { totalAmount: 14.53 } . So that apps can work with the data directly.
