How do I integrate scanners....

[dfate]

Hi all,
I'm looking for some information, links etc. on how to use the following
with Access and any help would be GREATLY appreciated!

1. How do I pop an Access form and pull up records based on the incoming
phone number from callerid? I'm basically looking to trigger a query on a
form to select where phonenumber = (caller id from incoming call)
2. How do implement a barcode scanner (usb...) to scan inventory in a point
of sale application?
3. How would I integrate a credit card machine for billing?

-THanks! Dave
