Design and Development of a Secure Online Platform for Real-Estate Transactions

ExactDeposit is an online tool that enables real-estate buyers to pay deposits on real-estate transactions electronically via credit or debit card. In addition to facilitating the deposit transaction, it will allow real-estate brokers and agents to log in and view transaction statistics both in real-time and historically. The tool will provide a user-friendly online form to accept agent and buyer input from any devices (laptops/desktops/tablets/smartphones). After being processed by the ExactDeposit server, credit card and destination brokerage information will be sent to a 3rd party gateway for final payment processing. The developed system will utilize the functionality of the 3rd party gateway by making specific API calls. Once the transaction is over, a response will be sent to the ExactDeposit server for post transaction processing. Email notifications of a completed transaction will be dispatched to all stakeholders from the ExactDeposit system. The database within ExactDeposit will store transaction ID, and state of the transaction, including information related to client mapping to the brokerage and vice-versa. This system will give the real-estate buyer – a secure, yet simple and flexible means of sending deposit funds and give participating brokerages the ability access transaction statistics.
