So let's put it this way, the trajectory we took was to weave everything around our students, our members. And I'm not just saying students because I then used the term members because initially we were restricted to students but soon as students graduated, they started working and they started coming with needs, so also did our students come with needs. And needs were not necessarily direct technological in terms of - I want to learn the screen reader, I want to learn how to use scanning software, etc. It went well beyond that. To list a few. This was an academic problem to start with. A student came to us with a book running into 800 pages on Indian economics and said, "can you give me a soft copy of this?" And I said let's scan it. He said that, "you can scan but you will never get accurate rendering for the simple reason that there are so many tables and things can go out of alignment. Can you not get me a soft copy from the publisher?" To cut a long story short, the publisher refused and it went back and forth. And finally, we decided why not try to change the copyright law which took us six years- in 2012 it changed. That doesn't mean that publishers are obliged to give us accessible copy. But at least then scanning is no longer a violation of the law. Some students came to us saying that, "Look I've got myself a job and my employer requires me to open a salary account. But the bank is not opening it." And again, social advocacy at work, we worked with the RBI and got them to change the rules. The rule was as crazy as saying that a blind person should be treated on par with an illiterate person, which meant that a blind person could never open a bank account on a single name. That changed around 2009 or 2010 I don't remember the exact year now. Around the same period, we started working on accessible ATMs. These are ATM machines which you can plug your headset into and the different functionalities are mapped to the keypad so that you can choose your language by pressing one or two, you can press increase volume, decrease volume, choose the type of transaction, enter your pin everything through voice inputs which you hear through your headphones. And so much so that you can even blank the ATM screen out so that if somebody is peeping from behind your shoulder, that individual would not get the opportunity to read what you are up to.
