Sounds dumb but hear me out.
Scenario, player wants to track their spending, their ins and outs and information on their money in the bank. Cool. Like in real life they can walk over to the bank use a teller command and get a scantron.
The bank could hold- lets say... Your last 30 transactions to keep it from going crazy and keep the data of if it was....
A withdrawal, a deposit, or a transfer.
It can also track the alias, the amount, account total, and date. So examples could be
Example:
Current Account Balance: 10000c
Transfer -1000c, JaneBlank, April 31st 2109 Account Balance 10000c
Deposit +1000c, JoeBaka, April 30th 2109 Account Balance 11000c
Withdrawl -5000c, JoeBaka, April 29th 2109 Account Balance 10000c
Transfer +15000c, CorpoChum, April 29th 2109 Account 15000c
You could limit a print out to once every 24 hours, but it lets players track their spending, but also has something far more interesting to steal. It goves information to others and is a utility, it tells relationships and not just money.
Advancing it, it could codedly give Deckers a thing they could crack and access in world if they get the right information.
If we wanted to obfuscate information like the aliases, we could in theory allow 'secure transfers' which could be just like a normal transfer but removes your alias from the statement for a fee, to stop the chore of changing an alias before a transfer for people worried about operational security and. Could also have transfers made between Cred chips automatically be these 'Secure transfers' which would give a more coded reason for people to carry around or use Cred chips for day to day use.
