A woman is paying online with card

Fraud prevention

If you run a brick-and-mortar shop, before concluding a payment card transaction, remember to make sure that:

  • The card is not damaged (cut, broken)
  • The card does not show signs of forgery or conversion (incorrect hologram, irregular size, a detached or faded magnetic stripe, decoloured or delaminated edges)
  • The four-digit number printed on the front of the card is identical with the first four digits of the actual number of the card
  • The Customer’s surname displayed on the terminal corresponds to the surname on the payment card (some types of cards may not feature the customer’s surname)
  • The signature on the terminal print-out is consistent with the one on the card (if the transaction is to be confirmed with the signature)

What about online fraud?

If you run an online shop, you are not able to verify the payer on your own, therefore in eService we provide you with a large number of modern security systems that protect you from a potential fraud. 

  • 3D Secure (Verified by VISA and MasterCard SecureCode)
    This system is a transaction security standard that works by identifying the card holder with the use of an additional, most frequently one-time password, either generated by TOKEN or received via a text message. To avoid other people obtaining the password, it is not used with transactions that require the physical presence of the card; therefore, it is never identical with the PIN code.
  • 256-bit SSL (Thawte SSL certificate)
    SSL (Secure Socket Layer) is a cryptographic protocol to provide security of information sent.
  • Real-time monitoring of all transactions
    The latest methods of data encryption guarantee reliable security of the transactions made.
