Inspiration

For the last couple of years, secure and anonymous methods of making transactions have been sweeping the news and a new method seems to pop up every so often. One that immediately comes to mind are Crypto-currencies. We decided to put our very own spin on an anonymous payment system using the Softheon PaymentApi.

What It Does

  • Users are able to request prepaid virtual credit cards that are provided by GhostWallet to make purchases anywhere.
  • The user first needs to sign up and pay for a GhostWallet Prepaid Card. Users are able to set how much money these cards contain.
  • The users are then able to use that card to make purchases anywhere on the internet through an anonymous card that doesn’t link back to their original credit card, thus preventing card fraud in case a merchent they use is compromised.

Advantages of an Anonymous Wallet

  • A user can make several Prepaid Cards to help them budget their money. A use case would be to make separate cards for “Groceries”, “Video Games”, or anything they like.
  • If a merchant that a user frequently uses gets their credit card information leaked the damage wouldn’t be as catastrophic as losing their actual credit card. This is because they would only have a single prepaid card (of hopefully small value) instead.
  • The user can share their prepaid card with others as well! You can give others access to your GhostWallet and pay them in that way (Better than Venmo since you are not restricted to peer-to-peer transfers).
  • More use cases that I am sure you can think of :wink:

How We Built It

  • We built a backend of this service using Python and Flask that acts as a middle-man between Softheon and the user.
  • First the user must be able to pay for the cards so they initially enter a card that they can use to get anonymous vCards.
  • Then we connect to the SoftheonAPI and request a new card (we have made several hundred prepaid cards ready to be lent out to users).
  • The user then receives the card and is able to use it up till the limit.
  • The UI was done with Android with heavy use of the VolleyAPI.
