I read an article about improving the administration of bank account numbers when you change bank.
They want to change the system so that you will be able to transfer your bank account numbers between banks. When you want to switch bank you take your number with you, the same technique as they use with today's numbers for mobile phones. It will become easier to remember your account number and it will also keep it simpler for everyone that needs to or transfer money to your account regularly.
Sounds great and you can sign my name to this cause.
