OPC secures your personal information entered into their Web site through Secure Sockets Layer (SSL) 128-bit encryption, which creates a protected connection between users and the web server. This means your card number and personal data are never sent over the Internet unencrypted. Official Payments uses the best encryption technology available. Card information is not passed to WSU and payment data is passed using hardware encryption. Transactions are processed using a leased line connection to the card issuers. Official Payments partners with VeriSign to ensure the highest level of security.
