One thing I don't understand these days about the banking system.
For years, you needed 3 things to transfer money into someone's account anywhere in Australia: BSB, account name, account number.
The BSB was a 6-digit number, the account number was usually at least 8. I can accept it probably isn't the friendliest system, but it worked.
Now, the modern preference is a "Pay ID". I've seen numerical ones, and I've seen ones that look like email addresses.
Yet, the Internet banking still expects the BSB, account name and account number.
How the hell do you convert from a "PayID" to a BSB/name/number? Clearly it is possible, otherwise banks would have a field for "PayID" or people would be using the old way instead.
