Payment modules

I need payment modules written for WPEcommerce, Magento, prestashop , oscommerce and zencart. The payment requires the customer to 1. Enter his valid phone number with the country code (pref a dropdown) 2. Enter a transaction authorisation code using the keypad to validate. 3. Approve the payments if the response is valid. The payment gateway supports activation of api service, single and multiple items payment, subscription payment , transaction authorisation request, and refunds I have written the class for all the transactions with the api, with sample codes, and explaination, which simplifies your job. I also added the styling, jquery for the touchpad for the transaction authorisation code keypad. What i require is basically using the class and examples to guide and build the modules for this shopping carts.
