Where there are two solutions:

1) The bank provides the service... you do nothing but call the number
they provide.

2) The bank provides some sort of API (authorize.net is common in the
United States of America) and you write code (an AGI script) that a)
accepts the input via the phone b) communicates with the bank using
the API, probably via the internet using some sort of encryption
(HTTPS is pretty common)

Answers to your questions:

1) Probably just by entering 5025
2) Probably just by entering MMYY (month, month, year, year. e.g.:
1210 = December of 2010)

This is rather simple since the format is known. Currency usually has
two decimal places and years are again a standard format. If using
option 2) above it would be wise to provide a confirmation (user dials
5025 and then a prompt would say "You entered fifty dollars
twenty-five cents. Is that correct?", etc.)
