STC Secure Transaction Channel
A patent-pending technology from V-One corporation which uses an 'out of band' end-to-end security method with DES and RSA public key cryptography to conceal and transmit transaction data to credit card processors over the Internet. STC reduces the risk of merchant fraud by not allowing the merchant to view in plain text any of the financial data contained in the encrypted envelope sent by the purchaser. The data is decrypted at a decryption server used by the merchant bank or credit card processor. The U.S. Departments of State and Commerce have granted export approval to STC. See CyberWallet.
