It will be considered a valid receipt for payment:

• If the payment was made at the cash desk of a bank, the "Contribution Payment Receipt" will be stamped or mechanically validated by the bank.
  
  
• If the payment was made through a cashpoint or by telephone banking or Internet banking, payment will be proved by the "Contribution Payment Receipt" and the receipt used by the bank, which will include the same account information for the electronic payment as the "Contribution Payment Receipt" and the date of the transaction.
  

The "Contribution Payment Receipt" does NOT imply that contributions have been paid if it is not accompanied by the proof of income, stamp or mechanical validation from the Bank.
