From a technical point of view, I don't have much to give in terms of feedback on what could be improved. But there have been some users who have been complaining about the interface being unfriendly and when the application software is installed on their phone making their mobile slow, a little bit laggy. It should be taking less processing. It just depends on the mobile phone. Apart from this, I haven't seen many use-cases of it being deployed on a large scale. We haven't had the experience of it deployed on a very large scale so I'm not sure how it would perform in that environment, so I can't say anything about this.
