Hi
I am developing a POS system for a retail business and I need to support
accepting the credit and the debit cards. This authorization interface need
to be integrated to the my POS application(vb dot net) I am building i.e..
my application will send the data to the hardware for authorization and gets
back the authorization status possibly using the COM ports.
So far I found out that the debit card authorization can only be
accomplished thru the PIN authorization hardware(althou gh the credit card
part can be implemented with hardware or software solution), so finally I
have come to the conclusion of using a some kind of hardware solution with
Credit card and the Debit card authorization built in. so that I just use
one piece of hardware for both.
Now my questions
1) Is this a good approach?(this will not be a very busy environment so
modem based hardware should be able to authorize the processing)
2) Do I have to go with specific kind of hardware(based on my customers
merchant account)
3) Does any one has better idea or suggestions?
4) Do I have to aware of something(missi ng something)
Any feedback is greatly appreciated
Thanks
