# Dove | Payments brought offline to users 
Dove is **an offline payment service**, built on the top of [PayTM APIs](http://paywithpaytm.com/developer/), which can be used on any mobile device (including legacy mobile devices which don't even have a GUI or provisions for internet connectivity) without installing any additional application.
We intended to target the demographics who don't own a smartphone or have proper internet access, staying true to "Building for India", the hackathon's theme.
Our efforts also highlighted a way for PayTM to increase their user-base.
This was possible due to SMS capabilities in every mobile device, hence we hacked on that to make and receive payments easily using a simple keyword **dove**.
We built this using :
* [Sinatra](http://www.sinatrarb.com/), Web framework for Ruby.
* [Redis](https://redis.io/), In-memory key-value data store.
We also used the following to imitate an SMS gateway :
* [Twilio](https://www.twilio.com/), cloud platform providing SMS APIs for text-messaging.
* A mobile application to route text-messages to a web-server.
## Setup
Requirements:
* Ruby
* Redis
* [bundler](https://bundler.io/) gem
Installation:
1. Run `rake install`. It will install `bundler` if you have not it installed and install needed gems.
1. Rename `config.json.sample` to `config.json` and replace `XXXX` with needed values.
Running:
1. Run the service with `rake run` or just `rake` in your console.
## Current Scope
### Register User
* Since registering a new user (unique : mobile number) is a 2-step process on PayTM, we implemented a similar logic.
* User can simply initiate the registration process by sending the following text to a **PayTM dedicated number**
```vim
dove (reg | registration)
```
* Doing this results in the user receiving a SMS with an OTP. He/She needs to send this to the dedicated number in the following format.
```vim
dove validate
```
Hooray! You successfully registered at PayTM (if you hadn't) and our service as well.
### Check Available Balance
```vim
dove (bal | balance)
```
### Send / Pay Money to another number
```vim
dove (send | pay)
```
## Impact
According to a [survey](http://www.thehindu.com/news/national/about-70-per-cent-indians-live-in-rural-areas-census-report/article2230211.ece) conducted by The Hindu in 2011, around 83.3 crore people still live in Rural India. In another [survey](http://www.livemint.com/Consumer/yT14OgtSC7dyywWSynWOKN/Only-17-Indians-own-smartphones-survey.html) by LiveMint, only 45% people in India owned a smartphone in 2013.
It seems we have created a possible user-base of around 83.3 crore people for PayTM. :v:
