This plugin allows admin to set a dedicated Virtuemart2 category to sell userpoints (AlphaUserPoints or Jomsocial userpoints) packages. For each item of that category, when an order is confirmed automatically, item price x quantity will be converted into userpoints and credited to the customer account according to a point/currency ration. Only settings for this payment plugin are in the Joomla plugin manager. Do not create a new payment method with this plugin. Also make sure this plugins is ordered as the last plugin in the VMPAYMENT plugins folder for it to work and make sure you installed the provided plgaup xml rule if you use AUP component (useless for Jomsocial).
