    USSD Outgoing Mobile PaymentContextA mobile money network is already operational in the country. Subscribers can deposit in or withdraw from their account, transfer money to each other or pay utility bills (electricity, cable TV)As the network grows, more services will be added, such as merchant payment for good and services, salary payment, invoice payment.The Merchant population can be segmented in two categories: the big department stores, with high volume and high traffic The small independent storesThe first category of merchants tend to have a sophisticated IT system and back-office, integrated to their network of POS (point of sales). They accept many different payment methods, such as checks, Visa and MasterCard, debit card, etc.The second category which this project targets more specifically concerns merchants and micro-businesses, operating essentially on cash, and generally with no bank account. The goal is to enable this segment to make and receive payments through the mobile money network.Description of the existing procedure1. The User dials a predefined string to initiate a USSD session2. The Mobile Money USSD gateway returns a menu displayed on the Subscriber’s phone.3. The Subscribers selects the desired menu item (e.g. Menu 2 : make a payment)4. The Mobile Money Operator’s USSD Gateway returns another dialogue for the subscriber to enter the beneficiary’s phone number5. The Subscriber enters the phone number and sends6. The Mobile Money USSD returns a menu to request the amount to be transferred7. The Subscribers enters the amount8. The gateway returns a menu to prompt for a password or secret code9. The Subscriber enters the password10. The mobile money platform sends an SMS to the Subscriber and the Beneficiary to confirm the transfer, along with their respective account balances and the amount of the transferObjectiveThe objective is build an application that will handle the USSD session data exchange after allowing the User to enter the required data.User InterfaceThe application User Interface shall allow the User to enter: the phone number of the payee (entity receiving the payment) The amount to be transferred The secret code (provided by the Mobile Operator at the time of registration for a mobile money account). Optionally this can be stored, provided adequate security is implemented for accessing the applicationApplication Process FlowAll the data initially entered by the User are saved1. The User initiates the payment request2. The Application sends the string for starting the USSD session3. The Application receives the menu4. The application sends the digit corresponding to a money transfer request5. The Application sends the phone number attached to the mobile money account of the Payee6. The Application sends the secret code (entered by the User, or internally stored in Settings)7. The Application stores for future reference the confirmation SMS received from the Mobile Money OperatorStatement of WorkThe work will require three incremental stepsA. Basic USSD session test: activation and data exchangeB. Proof-of-concept to actually execute a simple basic real- life payment transactionC. Application: detailed specs to be realized upon successful completion of 1 and 2 aboveHardwareProof of Concepts and Application should be run on Android tablets or smartphones

    Hello.I have a website at www.whereist.com The site uses wordpress & Geomashup plugin to provide information about locations in Turkey. I dont know much about programming but the creator of the Geomashup plugin said with the JSON REST API wordpress plugin (http://wordpress.org/plugins/json-rest-api/) and Geo Mashup"s Copy Geodata Meta Fields setting you can probably provide all the data you need to an app.Can we design a functional app for tourists coming to istanbul? A few features I would like:-photo or photos for each entry-map of locations within application with places around me. however for directions they can use Google Maps-if possible download all data at once. However I update the site and add new entries once in a while so I"m not sure how that would work.-browse by category- save to favorites.-search. if possible.i am also planning to do the same Android App for turkey.whereist.com as well as other applications that use Geomashup plugin.
