Automatically recurring monthly charges?

In the ‘Button Code Generator For Level #1 Access’, does the 'Monthly (recurring charge, for ongoing access), option result in ‘automatically monthly recurring charges’?

i.e. meaning the clients subscribing to the service will have their monthly charge taken, without them needing to do anything?

If so, I’m assuming the card payment etc. info stored with the payment gateway. If so, are there particular payment gateways that need to be used for these ‘automatically monthly recurring charges’?

Q1: Yes
Q2: As far as I am aware all the gateways supported by s2member support subscriptions. I have only used Stripe and PayPal. They both support recurring auto-renew subscriptions.
