Handster has released a solution for integration of payment into shareware programs for Windows Mobile Pocket PC devices. Integrated programs have a 'Buy' button in the menu and show a "Buy/Try" screen on startup.
On clicking the "Buy" button in the program the user can enter credit card information directly on the PDA. A secure SSL transaction is executed via GPRS (if available) or via ActiveSync when the PDA synchronizes with an Internet-connected desktop PC. Once the payment is completed, the application gets unlocked automatically.
The company sees this as time saving feature for end-users. There is no need for registration codes to be entered because the program is unlocked automatically once the payment is processed. This eliminates the risk of registration e-mails getting lost because of spam filters.
If the program trial is expired, users can the credit card information and use the program for some additional time. Once the handheld is connected to the Internet, the payment is automatically completed and the program is unlocked for unlimited time.
