Boleto Bancario [Brazil]
This is approved by the FEBRABAN (Brazillian Banking Federation). Most brazillian based e-commerce sites use this direct payment mode in wich the money is transferred directly via bank transfer. The buyer recieves a bill with a bar code that can be payed at the bank of his choice and the money goes directly to the shop's bank account without any other middlemen. It is preferred by many in Brazil and most sites encourage paying through this method by setting discounts if the costumer choses to buy with a boleto.
I firmly believe that by implementing this method you will gain many more brazillian costumers that are currently using other e-commerce platforms because of the existence of this gateway for their platform.

At the moment there is a plugin already paid for it.
I intend next year to develop some free plugins for this purpose.
