The present invention relates to a “double recognizing method by means of
telephone number and identification code for online
credit card transactions over
the internet,” in which the
credit card holder not only registers a “self-chosen code” by himself / herself for VBV (Verified By VISA) or MSC (
MasterCard SecureCode) network identity
verification but also registers another set of “
telephone number and identification code” by himself / herself for serving as an exclusive personal double identity recognizing information for online
credit card transactions. The credit card
issuing bank registers and stores the set of “
telephone number and identification code” on a double recognizing
database after checking truth of the related identity
certificate provided by the credit
card holder. When the credit card
issuing bank handles the online credit card transaction of the credit
card holder over the network, the credit card
issuing bank not only proceeds the check on the “self-chosen code” used in the original VBV or MSC
verification system but also performs the
double check on the “telephone number and identification code” used in the
telecommunications transceiving processor platform of the internal credit card double recognizing computer
system, for example by sending out a short message to the credit
card holder for requesting him / her to immediately reply by another short message to his / her “telephone number and identification code.”
