I've been into a few stores recently to look at self checkout. I've found an
interesting approach in the Wal-Mart stores I've visited (other stores may
use the same approach). At the point where you select payment you have
choices that include credit card and debit card. Even if you select credit
card, if the scanner detects you have debit capabilities it takes you to the
input pin screen. There is no indication that you can hit cancel and then
select the credit option. Though you can. Obviously this is a business
decision given that debit is less expensive to process than credit. 

What would you do if you're the IA/IxD on that problem/solution?
