It used to be, not long ago, something of a trial to deposit cash or cheques an an ATM. First extract the deposit envelope, fill out the details on the integrated deposit slip & insert it along with any cheques or notes, then, while the queue that's building behind you gets frustrated at your slowness, insert the filled envelope into the belly of the beast.
Now, though, you insert cash notes, cheques or a combination of the two up to 40 items directly into the machine, which scans each item & adds up the totals.
If there were any cheques in the deposit, you can opt to have scanned images of them printed on the back of the issued receipt.
Too easy.
