Where can I find a "map balance" plugin or solution for a CMS (wordpress or drupal)?

Question

PHP

You need to implement a fuel card (for refueling).
I want to implement such an opportunity on one of the two CMS (which is easier) such an opportunity:
Administrator
1. Creates a card (user) with the fields name, card number and balance
2. Charges him the amount in rubles
3. Has the ability to search by user's card number and edit balance
4. See when what was edited by which user
Advise a plugin or solution so that this minimum of functions has already been implemented, it is necessary for refueling to issue fuel cards.

Answer 1

I doubt there is such a plugin. The task is too specific.
But on WP you can easily do it.
We make social networks, knowledge bases and CRM / ERP systems on it for distributed companies with 1000 employees.
Making fuel cards is not a problem at all :)

Answer 2

in the same place as everyone else: https://drupal.org/project/balance_tracker very convenient api for the module.
and there is also https://drupal.org/project/userpoints , but it is not so convenient.
