In one example, our mobile application and system provide users with a way to sell/buy books to and from those around them. Users would first create an account linked to their .edu email address. Using a third party payment program, the user then links their payment information. This allows for the transfer of money safely with the security of this third party company. When a student or any other user wants to sell their book, they log into their account and can then enter their course number, book title, description of condition, and selling price. This can be automated by simply taking a picture of the ISBN or bar code, and it automatically populates the fields, allowing the student to change the price and condition. Other variations are also shown in the specification. |
