The Special Codes Management application allows the creation of a "username" and "password" pair for specific services, such as those found in the "Available Services" section. By using one’s TAXISnet access codes, one can log into the Special Codes Management application.

The special code pairs are separate from the main TAXISnet access codes and different per supported application/service. The special codes are an additional means of security, so that you do not have to share your main TAXISnet access codes with others when required to use one of the supported applications. For example, with the special access codes, you authorize a program/software to submit information about you, without revealing to the software manufacturer or operator your actual main codes.
