In online or remote sales, your employees and/or computer systems must be prepared to recognise suspicious orders. Our experience shows that are certain common characteristics in frauds. If the transaction has one or more of the following indicators, it may be a sign of increased risk:

  • Customer for the first time. The risk of fraud is smaller when you are dealing with regular Customers;
  • Big orders. Orders that include several items of the same article;
  • Suspicious cards combinations;
  • Transactions performed with cards with similar numbers;
  • Orders sent to the same address, but purchased with several cards;
  • Multiple transactions performed with one single card in a brief period of time;
  • Multiple transactions performed with several cards and different delivery addresses;
  • One single transaction in which the Customer wants to pay with several cards;
  • Hesitation. Be aware of the Customers that hesitate or feel insecure to give personal data;
  • Sudden orders/ orders performed with hurry. Orders with an urgent delivery request. These last minute orders are a characteristic of “hit and run” fraudulent schemes to obtain goods to resell quickly;
  •  Random orders.​

In Online Sales, the following procedures will help to diminish the risks of fraud:

Implement fraud detection systems to identify high risk transactions or transactions patterns.

Don’t make transactions with high risks characteristics, such as:

  • Transactions that exceed your store’s normal sales standards;
  • Orders to high risk addresses, such as PO boxes, prisons, hospitals;

Check carefully orders made with several cards or with cards that have sequential numbers, as it may be evidence of fraudulent activity.

Be aware of international transactions.

Assess the risk based on the type of goods, the amount of the transaction, country where the card was issued and to which the goods must be shipped.

You must check if the order has any suspicious, unusual names or spelling errors.

If the situation is suspicious, contact our support line 21 313 29 00.

Face-to-face sales2020-03-18T01:25:18+00:00

In what concerns to Online Sales, to diminish the fraud situations we advise you to follow these procedures:

  • Always get authorization for all the purchases orders. The authorizations show if the card is valid, in which conditions shall be used and if it has enough balance to perform the transaction; Always obtain the security code associated to the card of the customer (CVV2/CVC2);
  • Keep a register of the purchases made by the Customer. Fraud is less likely to exist if you keep a regular business relationship with the Customer (greater than 6 months);
  • Establish and analyse the maximum amounts of each Customer; Determine the frequency of the transactions performed by the same Customer;
  • Keep registers of the deliver addresses used by the Customer; in case the goods are of high value, check the purchase with the Customer;
  • Keep a list with registers of returns or complaints based on the delivery address;
  • In case a return is requested, guarantee that it is always made for the card that performed the transaction, whenever possible, and if you specifically receive orders through fax, mail or telephone, always ask for a Customer’s signature on the order form.
Face-to-face sales2020-03-18T01:27:58+00:00

When it comes to face-to-face sales, we recommend that you follow these guidelines:

  • Guarantee that your customers enter the security code (PIN) away from obtrusive eyes;
  • Sensitize your employees to, when they are dealing with your customers, comply the security rules of the bank cards;
  • Always check the expiration date of the card;
  • Always check the condition of the card;
  • Always be very careful reading the messages on the terminal;
  • Keep the invoices in a safe place;
  • As a security add-on, in case of doubt/suspicion about the identity of the user of the card, ask for a valid identification document to confirm it;
  • Never look away from the terminal and always check if the data of the receipt are correct (amount, data and time of the transaction…).
Very important information about fraud prevention.2020-03-18T11:36:26+00:00

REDUNIQ never contacts merchants asking for their customers’ bank data, or asks for debit/credit card numbers or any other identification data of the cardholders.

REDUNIQ never gives the merchant the information about the authorization codes to be used before the merchant submits the transaction request or authorization with his customer’s card, because that code only exists after the merchant submits the transaction.

Whenever there are questions about the identification or suitability of the person that contacts the merchant in behalf of REDUNIQ, you shall contact the Unicre Service Centre, that operates 24/7, by calling the number 213 132 900.

Other procedures may help to diminish the fraud situations.

Who must perform a PCI certification?2020-03-18T15:17:38+00:00

Every merchant must fulfil the PCI security requirements.
To assess which certification level to perform, each merchant must read in www. pcisecuritystandards.org the validation requirements mandatory to each merchant category.
The classification of each category crosses the merchant’s number of annual transactions, the acceptance channel where the transaction occurs and the merchant’s level of risk.
The distinction between the validation requirements and the subsequent proof of compliance required varies according to the level of risk at which the merchant fits.

Level Criterion Proof of compliance
1 Merchants that:

  • Perform more than 6 million transactions per year, independently of the acceptance channel;
  • Have suffered an attack to their computer systems that have compromised his customer’s cards data.
AOC – Attestation of Compliance
2 Merchants that perform between 1 to 6 million transactions per year, independently of the acceptance channel;
3 Merchants that perform between 20 thousand and 1 million e-commerce transactions per year;
  • Prove the business relationship with the certified services provider (listed in www.visaeurope.com and MC), and
  • Present a self-assessment quiz (SAQ Self Assessment Questionnaire)[1]
4 E-commerce merchants that perform less than 20 thousand transactions per year;

 

How to obtain the PCI certification?2020-03-18T01:39:56+00:00

The PCI certification may be performed using a qualified security consultant – QSA (Qualified Security Assessor), that is certified by the international Payment Systems or by an internal security auditor of the merchant – ISA (Internal Security Assessor), that has concluded the ISA training program, developed according to PCI Council criteria:
