User Self choosen ID refresh/create setup Howto ?

Hi,

I have setup Mikrotik ROS with PPPoE / Userman .
I want to provide my users with voucher with scratch card with serial/code, so users can create his own id, and after expiry user can refresh his old ID with the new scratch card.

How to setup this ? So users have the signup page whether to create NEW ID or REFRESH old ID ??

It’s possible only with payments support. Only with money transfer over Paypal, Authorize.net automatic account refresh is possible.
Sign-up is possible only for HotSpot, it’s not possible to use with PPPoE.
