Deliver software license codes

Sell software license keys online ....

This is a PHP / MySQL application that you install on your web site to sell and automatically deliver license keys to a customer after purchase from PayPal. These may be mobile pin numbers, key codes or be any other form of license codes.

PHP-KeyCodes provides the checking of the completed transaction before the codes are sent out to the purchaser by email. It is an automatic delivery system where the top license code or pin number is extracted and automatically sent to the customer without any intervention by yourself.

The application does not create the pin numbers themselves although there are a set of php functions which can be modified to do your own custom processing, for example, create a pin code based on the customer name.

The customer does not have to have a PayPal account to purchase an item but can use any supported Credit Card. PayPal then becomes just a payment gateway for the credit card.

Main features

  • Keys are stored in a table in the database for each product and the top one is extracted when purchased.

Security

There are a number of checks in the script to ensure that the data received from PayPal has not been modified. The license key will only be sent out when all checks are correct.

  • The script checks the transaction id in the database to make sure that it has not been previously used.
  • The cost and currency of the item is checked to make sure that it has not been changed.
