Credit Card Company S
Internalizing e-document verification on blockchain
"Samsung SDS’ Nexledger Solution saves us cost and helps secure stability in operation by internalizing the function of original e-document verification based on blockchain, which used to rely on external parties."
Credit Card Company SChallenge
Korea’s biggest card company that provides card payment as major services creates card application forms and contract with stores collected by credit card salespersons nationwide, which is about 1.7 million set a year. It is, therefore, very important to manage the mentioned e-Documents without any information leak in safe and efficient manners.
Previously, Company S had to pay for service charge through the Authorized e-Document Center in order to carry out the process to verify original documents as a part of document management. As the center is an external organization, there have been some service error risks in operation.
Solution
The Nexledger Solution internalizes the original e-document functions by saving the time stamp information and documents’ own hash values.
