I had an idea for my first mobile application and I was thinking of making it in HTML5 + Jquery Mobile. The core functionality is:
to be able to take a picture of a receipt
digitize all the information.
I've never made a mobile app before and I'm not sure if this is possible. If there is no API available, how would I go about rolling my own receipt reader? Thanks! Please let me know if I am being stupid.
Edit: I found a service that lets me use their application to take a picture(or e-mail the picture) of the receipt and have it extract the necessary information. http://www.proongo.com/b/receipt-reading.php. I'm not exactly sure how to use this service but I will do more research tomorrow and share with you what I find.
I found an OCR API service with a number of different pay-per business models called OCRAPISERVICE. They have a number of examples hosted on github using various mobileOSs through PhoneGap. They do have a free-trial model that lets you submit 100 requests.
I guess you need to apply OCR for software solution with a function of recognizing supermarket receipts. There are many open source OCR solutions like Tesseract and others. However, they are targeted to general OCR. Therefore, you have to use some additional tools for recognizing receipts via a mobile app.
Recently we have worked on the web-based app for receipt recognition. Here you may find some details of the research: http://rnd.azoft.com/applying-ocr-technology-receipt-recognition/
Besides Tesseract, all the big boys: Google, Microsoft and IBM have now got their own offering of OCR APIs. These APIs provide simple image-to-text OCR scan with various degree of accuracy. I find Google Vision to be the most accurate for pictures of a receipt. You would still need to extract the data out of the half-garbage text though.
If you want an API that returns field metadata like: total amount, tax amount, date and merchant information, where you apps can consume directly. Check out https://www.taggun.io. I've built the APIs specifically for this purpose.

I'm looking for an OCR solution (library/service/API) that be able to recognise fields from identity card/passport/driving license. Preferable a paid cloud service.
Edit:
To clarify, I'm looking for any solution (open source or not) that be able to detect: first name, last name, dob etc...
Go for BlinkID iOS SDK (https://microblink.com/products/blinkid/mobile-sdk) It is basically providing the best results.
You can also download the demo iOS app available at Appstore and check for various documents.
Accura Scan (https://accurascan.com/) is also competitor in the market which provides the accurate results recognising the MRZ as well as PDF417 code format. Accura Scan scans the below documents:
All countries Passports (with MRZ code)
DL of all countries except that if India and Philippines.
Alien cards/ID cards
Also, scans QR code/Bar-code.
I have not personally used any but some cool ones are:
Google OCR
Tesseract OCR (open source)
#QuangLihnLe, I just want to clarify, first you need detect passport / id card text with OCR, then validate or parse text as MRZ Text data. MRZ is a standard format for passport / id cards it contains sets of personal data including name, surname, birthday, expiry date etc. I have used MLKit to recognize MRZ data on passport and I made samples.

I have created a Chrome extension that I would like to give away for free, but provide a "tip jar" on the extension's options page where people can, if they want, opt send me a small amount of money to show their appreciation. I've looked through the documentation for one-time payments and Google Wallet for Digital Goods, but nothing I see there seems like a fit. It seems like the only options listed are:
Free extension, no payment mechanism: Not desirable because I want to offer people the option to pay something.
Paid extension: No, I want it to be free.
Free trial: This will make people think that the extension is limited in some fashion unless they pay, which it isn't.
In-app purchases: Same as above. I'd rather that my extension not be marked as having in-app purchases, since there is no limitation that you have to pay to remove, and the only thing paying gets you is good karma.
Is there a built-in Chrome Web Store option that is suitable for what I'm trying to do? If not, can Google Wallet be leveraged in some way to provide "tip jar" functionality, or will I have to find some other payment mechanism?
A lot of developers implement voluntary tips via PayPal donation buttons.
One could simply add the button to their options page. E.g.: [1] [2]
Cautionary tale: PayPal can, in principle, throw a hissy fit over collected funds, but as long as you don't rake in thousands you should be okay.
Please note: Fundraisers that are not verified nonprofits will be asked to demonstrate how their donations will be used, once they raise more than $10,000
Patreon is currently gaining popularity. I know at least one extension (Enhanced Steam) that went that route.
You may use ko-fi for this purpose: https://ko-fi.com/

Currently I'm working in a team creating a custom POS solution. We came to a point were we'd like to integrate with a IC/Credit Card terminal (like VeriFone which we have, i.e. Vx510). I think the simplest mode is to allow Cashier to manually enter into the terminal the amount a client has to pay. In more advanced (the desired) way our POS will send to the terminal the amount to be payed.
Regardless of the "mode" we'd like to get the information from VeriFone if the transaction was successful or not. Here's the dead end we've reached. AFAIK, to program VeriFone terminals or integrate with it you have to become a certified VeriFone developer. If it is so, then I know where to start. If not, please let me know.
Are there any other ways to get information for a terminal that the payment was successful? Are there any 3rd party libraries to communicate with this kind of devices? The most relevant to my problem SO thread I could find is this but it wasn't much of help for me. We don't want to process any confidential data, therefore we don't want to integrate with Authorize.NET
Ok, things got clear a bit... It turns out that if you buy a device from a manufacturer (e.g. VeriFone) it comes "clean", so you have to program it all by your own and satisfy PCI Compliance. Therefore, you have to be certified developer... at least for VeriFone devices.
However if you order a terminal from some kind of 3rd party provider, for example SIX, or Polskie ePłatności (one of the providers in Poland), it comes with some kind of, let call it "firmware". This "firmware" will, or at least should provide you an application for performing cashless transactions. It also should come with handy communication protocol. Of course you'll have to sign some kind of NDA.
In short:
If you want to integrate with a credit card terminal just call a local credit card payment service and ask them to send you a terminal you want to integrate with. Keep in mind that every country has its own transactions centers so your solution will be country-wide.
payworks offers a SDK to integrate a credit card reader within an iOS/Android app. They manage the connection from the card reader to the merchant's bank. You never have to touch confidential data.
Regarding Verifone terminals, they support the Verifone e105, e315, and e335. You can see the full hardware list here.
Disclosure: I am a software engineer at payworks.

I have an applicaion, that can best be described 'loosly' as a scripting application, primarly designed for part time developers, engineers and sciences types with a VB.NET background (can theoretically do C#).
This has been a long three year hobby and I am about 95% complete. I am planning to make the applicaiton freely available for most (if not all) uses, but I do not want to open source it (at least right now).
I was looking for an online place to post and collaborate with some folks for feedback, to get some testing done and finalize the application (my wife wants me to be DONE with it). My searches online have revealed many spaces, but all seem to be open-source spaces that require release of the source code, or just aplace to post 'free' completed software. I am looking for the collaboration part.
Can anyone point me to a such a space that does not require providing the open source code (if it even exits)?
I think you can use most of the collaboration places without actually uploading any source to the repository.
I've seen a bunch of project on Google Code Hosting that have no source (usually its then on GitHub) and just use the Google Hosting for bug-tracking and collaboration.
I created a BitBucket account. Looks like it might work. Many of the sites require you to choose an open source license before you even create a space. BitBucket does not.

There are plenty of statistics/analytics providers for Internet deployed software (e.g. Google Analytics), but I'm looking for an analytics tool to integrate into a LAN/intranet based web application.
I'm aware of AWStats, but I'd prefer something with a design similar to Google Analytics, where a Javascript callback can be embedded into the app and call back to an analytics server. This doesn't require any sort of extra application server configuration and access to run.
I'm thinking there's nothing available that isn't proprietary / pay-for, but I'd love to be told I'm wrong!
Piwik should be able to meet your needs. It's not as advanced as Google Analytics, but it uses a Javascript callback and can therefore give you more info than AWStats and Webalizer.
There is also Webalizer, but its pretty ugly.
You can look at Mint, it isn't free, but it costs $30 for the site, forever, so it is really a bargain for any large site.
Piwik works great and I use it on some Intranet sites without a fully qualified domain name. But note that Piwik needs PHP to run. I've used it on Lunix and IIS servers though.
If your intranet has a fully qualified domain name (ours is intranet.example.com, for instance) Google Analytics will work just fine. The admin interface will never tell you you've installed the tracking code properly, but it will collect data just fine.
I haven't tried it on a domain-less URL like http://intranet/. Worth a try, though.
