Payment services subscription service?

And here's an article with Habra habrahabr.ru/blogs/eCommerce/52083/

I suggest to use as widely as possible all possible channels of receiving payments into their system.
This can be achieved very quickly by connecting to any integrator (there are several to pick), for example ROBOKASSA.
In one fell swoop will be available to numerous ways of payment such as:
1. With the credit cards Visa, Mastercard.
2. From the user's mobile phone
3. Through the Contact.
4. Through ATMs of many banks.
5. Through numerous terminals of reception of payments, including payments
6. Through numerous payment systems like WebMoney

The most appropriate subscription, in my opinion, is the subscription through Visa/MasterCard. The money will be able to lift themselves at the right time.

Well, there are different ways. Depends on what you want.
For example via SMS, there is 40-60% you will not get it, but there are services subscriptions. That is, enter into a contract with an aggregator, create a project. After that, people can subscribe to the service on your site, the frequency you do expose. For example, once a week the subscriber will receive SMS like send SMS to such a number to extend the subscription to such a service on this website, you can unsubscribe this number.
It is possible via payment terminals, QIWI, or even that there percent less.

In General, it depends on what kind of services are going to provide.

If we are talking about Qiwi relatively simple (balsa part is easy)
We ask the user his phone (cell phone) and write him a bill. Remember the telephone, the account number and the user has purchased. Sent to qiwi account and stupidly waiting for payment. Once a person has paid, we receive a request from qiwi where an account number (or a request to reject the payment). All. You have the payment, you can give the content/product.
