Build Braintree(Paypal) Demo

Written in Asp.net C# This mini project includes building the demo for Braintree payment gateway, that our database should save the user credit card detail as a token and saved in the database. If the app user choose to use the saved credit card of his own one, our system can charge the credit card(it is a token saved in our database and a masked credit card such as 4444 xxxx xxxx 1111 to be presented to the users) directly without asking him to authorise it again. Very similar to How Uber APP is doing. Braintree offers something called Vault that it will save users credit card. We need the full demo include the code that written in C# A successful demo will include: Step 1: let the customer enter their credit card, the credit card information will be sent to braintree, it will return a token, masked credit card. These two will need to be saved in the database. Step 2: Charge the token and $100. When both step1 and step2 are finished. We need to do one more scenario, where when customer fill in their credit card detail, we charge him at the same time, and save the token in the database.
