In the following scheme you can see analytically the ePay service operation
method in a consumer-buyer’s typical attempt to purchase products from a
business-seller that uses the ePay service and to pay with his VISA or
MASTERCARD.
During the transaction, the Buyer will be called to give some personal data
(Name, Address,…) which will be transmitted from the Seller’s site to MARFIN
EGNATIA BANK’s server using the https protocol (SSL, 40 bit encryption), by
providing, in this way a satisfactory security level for these data that are
not of paramount importance for the transaction. The same security level (SSL)
should be also supported by the Seller for its customers, even though it is not
obligatory. After that (reaching the most important part of the transaction,
the Buyer is called to give the number of his VISA or MASTERCARD, the
holder’s name, as well as its expiration date.
In this point, the ePay service is already in control and activates one more
channel of communication, through which these data will be transmitted and the
whole transaction will be completed. This channel (it appears in the scheme in
brown color) uses the highest security level that is now available in Europe,
supported by asymmetric codification algorithms at 128 bit.
In this way, the secrecy of the transaction is safeguarded in the best possible
way (see the Transaction Security unit)
