MasterPass is a simple, convenient and reliable tool for making fast and safe payments on the Internet. MasterPass allows you to enter the requisites of the card only once during registration, and by making further payments enter only the login and password/PIN-code for authorization in the payment service. All cards that are added to the SharPay application are stored in MasterPass.
The PCI DSS standard provides safe transfer of payment card requisites on the Internet.
3-D Secure is a technology for verifying the authenticity of an online payment. If your card supports 3-D Secure, then in the process of transferring money you will see an additional window, in which it will be necessary to confirm the use of the card by entering the confirmation code, which will be sent to you by your bank in the message.
