Subscription charges

I'm in the process of creating an app, which would work with a Freemium type of subscription.

I haven't had to handle payments b开发者_开发技巧efore, so is a bit of a challenge, especially since all the resources I find seem to deal with only a checkout approach, you pay and off you go. Here is slightly different as the charges would be monthly and credit card info needs to be stored, and protected.

has anyone had to deal with this before? Any suggestions, gems, tutorials, resources are highly appreciated.

Thanks!

You might want to save yourself the trouble and go with one of the subscription billing services:

chargify, Spreedly, Cheddargetter, Recurly, Costify...

For rolling your own, ActiveMerchant is a great gem for interacting with payment gateways.

Spreedly is getting a lot of good press at the mo if you're happy to unload the responsibility of billing to a 3rd party.
