Payment choice not to bank account
Members can also decide if they want to get paid directly through a Halcash ATM withdraw(sacar el dinero directamente de un cajero con Halcash), so I believe we shouldn't add as a form neither the SPARK payment method(get their money in their anonymous SPARK debit cards).
I think SPARK and Halcash should be just payment options explained on the confirmation payment msg sent to the member and if he wants SPARK or Halcash, he can just communicate with the admin through the msg thread.
By statistics, most people get paid in Betabank or BoC anyway.
