Clear the Current Item in the "Smart Entry Display"

Tap the "Smart Entry Display" at the top of the screen to clear the current Item being added to the transaction and re-enter the Item if you've made a mistake, it's that simple.

If you've already "Entered" an Item to the transaction tape and you want to delete the Item from it, tap the Item's "$ value" in the scrolling receipt tape at the far right of the screen.  This removes the item from the receipt tape and clears it from memory.
