I think banking should be somewhat anonymized into a account numbers for the purpose of handling financial transactions between parties and corporations. Right now it's using character name and it's kinda ooc.
* Knowledge of someone's bank account number would be hack-able in the new grid and able to be cross referenced perhaps with SIC ID. Probably via tac-comp as well or perhaps as an Ops specific function.
* Corporate accounts should be even trickier but perhaps require Papers of Incorporation to open but added layers of protection.
* Sharing your account number with a corporation for direct deposit in a payment terminal would be beneficial but also open you up to risk as that information would be available to HR.
Launder your money like a corpie or deal in cold hard cash as a mixer.
