Payment Methods

PROZIS may offer different payment methods for purchases made through the online store. The conditions of use established by each of the payment service providers shall be applicable. For that reason, PROZIS cannot be held responsible for any additional costs charged by those entities.



Credit card


The customer can make the payment using a credit card and so benefiting from the liquidity and payment conditions offered by their bank.


Is it safe to make an online payment using my credit card?

All transactions on our website are secure.

PROZIS uses a sophisticated fraud detection and prevention mechanism. Through this solution, it is possible to verify the authenticity of payments made online, simultaneously ensuring the integrity and security of the customer's data as well as their identification. This security is enabled by Secure Sockets Layer (SSL) technology, which encrypts communications between customer's software and our server, so that communications cannot be intercepted. Therefore, PROZIS reserves the right to refuse the payment of an order if the transaction is found to be unlawful or if it constitutes a serious suspicion of unlawfulness. Any and all activities deemed illegal will be immediately reported to the competent authorities.


3D Secure

3D Secure is a communication protocol designed to improve the security of online payments and to enable the authentication of the credit card user by the credit card issuing bank. Once a payment of an online purchase is made, a process to validate the card used is triggered. Should the credit card be considered valid, the security systems associated with the 3D Secure protocol verify the customer's identity, resorting to the credit card issuing bank in real time, which, in turn, validates the customer's identity and reports confirmation that the card used is legitimate. Such control is intended to protect credit card holders by reducing the likelihood of fraudulent use of their cards, thus ensuring a more efficient transaction. This protocol is used by Visa under the name "Verified By Visa", and by Mastercard under the name "Secure Code".


How is the credit card payment processed?

After selecting the credit card payment option and clicking "Buy" on the last stage of the purchasing process, the customer will be redirected to the webpage of the entity providing the payment transaction. On the said webpage, the required details of the credit card shall be entered, including the credit card number, the expiration date and the respective security code. In that sequence, the customer should click the "I validate my payment" button.


Should the payment be declined, a message will be sent to the customer with the indication of the detected error. In such event, a new payment attempt is recommended; if the problem persists, contact with the respective bank or the credit card issuing entity for further information is recommended.

Once paid, the amount will be debited from the customer's credit card account. If, for any reason, there should be the need to cancel the order, in whole or in part, the paid amount will, under regular conditions, be refunded within five business days. Predictably, the transaction will be reflected in the customer's card statement after three business days from the date it was made.


Remark: Payments may be made in Euros, even when prices are displayed in other currencies, depending on the chosen payment method. Some banking entities may charge exchange rates. PROZIS is totally unaware of this fact and therefore takes no responsibility for it.
