At Shirofune, we make credit card payments using the services of businesses that comply with the "PCI DSS *", which is the global security standard of the credit industry.
* What is PCI DSS? Https://www.jcdsc.org/pci_dss.php
And there are security measures that are obligatory to use the services of businesses that comply with "PCI DSS". This is a measure to "non-hold" credit card information.
"Non-retention" measures are security measures that do not store, process, or pass card information in devices (servers, etc.) and networks at member stores (our system).
Naturally, we are compliant with this "non-holding" measure.
Therefore, the credit card information you enter will be registered with a business operator that is compliant with "PCI DSS" via an encrypted communication path called HTTPS, without going through our service.
Credit card information will be treated as encrypted data even in subsequent credit card payments and references, so it is a mechanism that can be used safely and securely.
