-calback communication system.

-retrieve datas (through http request with JSON answers) like :

* balance of the account.

* calls history.

* call fee for a given destination with the phone number prefix.

* User PIN number.

-direct payment:

* paypal module (paypal clients / credit cards).

* be prepared for futur integration of our own payment gateway.

-posibility to 'invite friends': through SMS sending: for new clients that have been invited: X € balance for free. If the new client make a reload then the 'inviter' will receive an X € reload for free (once).

-map with providers network (goolge maps with posibility of itinerary calculation).

-security:

*the user cannot change the phone number.

*the user can change the device with the same phone number.

*the user can change the sim card with the same phone number.

Installation and setup scenario:

- the new user can download the app from the store.

- will be asked for his phone number.

- for first time 'how to' screen.

- first launch the user is blocked on the payment page for reload.

- once reloaded the user will receive by SMS his/her PIN number.

- will be asked for a X digits PIN (generated at the moment of the 1st reload).

- user will be created in local DB with the phone number.

- can start to use the app.

- PIN number is persisted in a distant DB (not in local one for security reasons).

- SIM serial is persisted in a distant DB.

- Serial device number and phone number are persisted in a distant DB (for further verifications in case of phone changes or format).

launch scenario:

- no datas are asked to the user to launch the app anymore.

- the app must ensure the device serial number and SIM serial used by the user are the same as the ones recorded in the distant db (serial device number, SIM serial & phone number which are stocked in local DB).

[login to view URL] all datas match:

*the main activity is launched showing the user’s balance.

[login to view URL] SIM serial and phone number are different:

* show the ‘new pin’ activity and the user must ask for new 6 digits PIN (sent by sms).

[login to view URL] device serial is different (phone change):

*launch ‘new pin’ activity and the user must ask for new 6 digits PIN (sent by sms).

for case 2, 3 :

*new security pin activity is launched, asking the user for the new 6 digits PIN => ok => 1.

case no local db exists:

-ask the user phone number.

-check in remote DB if phone number exists:

-if exists => check device serial and SIM serial.

-else => ask for new PIN.

call scenario:

- call from history, favorites, contacts or direct dial (All number format : 00..., +34).

- dialog or screen to confirm phone call rate, number and destination.

* cancel => nothing happens.

- dialog/screen saying ‘wait for the next incoming call’.

-a call will be received from a fixed number (say 999999999) for all the users of the app it will always be the same number (nationwide).

-once the incoming call answered, the destination is called (as an outgoing call) and an overlay/screen has to show the approximate duration/costs of the call.

-call ends: dialog/screen with phone call details: real cost, duration and destination (provider). Last call added to history.
