It depends on what kind of code you usually use for your product. Typically I write valid function - if summ of money different a lot - clean field for tender and ask again...

>In our POS Application, users will sometimes inadvertently scan a barcode when the app is expecting an amount tendered (a numeric field). Since the scanner is set to add a CRLF the app thinks the amount tendered is some huge amount and happliy tells the cashier to give the customer a nice fat amount of change.
