Account types
From WirelessOrbit
Account types define the basic behavior of the Account classes that use them. In general, account types are defined by the method of access expected for the account.
Device Account
Device accounts are intended for wireless-enabled devices that don't have a web browser or similar interface available for user interaction.
Device accounts are permitted to be passwordless, but they may also have passwords defined.
Timecode
Timecodes are typically used for pre-paid and pre-printed account cards distributed at a point-of-sale. They have a randomly-generated username and no password.
User Account
User accounts are defined by the standard username/password combination, and are intended for general use.
