The data from the new account HTML form is saved in a database on a Windows NT server and transferred to the mainframe in a batch process. The HC receives the menu of the available host transaction options from the mainframe, translates the information from SNA format, and passes it back to the WCM as flat data. WCM activates the UA for a second time, now with menu of available host transaction options. The UA now calls the WCM to execute the account statement request from the customer. The WCM then communicates with the HC, which uses the same SNA session used previously to request the account statement option from the mainframe host.

The digital certification process requires the submission and verification of a digital signature that uses a public-key signature algorithm for encryption and decryption. Using Authenticode technology, the browser verifies the validity of the certificate and matches the web page URL with the one listed in the certificate. If the certificate is validated, the next step begins. The browser and server exchange a series of messages secured by the public and private-key signature to establish a session key which will be used to encrypt all remaining communications during the session. The tests were carried out both on the individual components and at a later stage during integration and acceptance tests on the Bank's system.
