The second tab “Amount to Pay” is probably the tab one will use the most. Before using this tab one  has to go to the “Wallet” tab and enter the different bill denominations and coins one have in their wallet.

Once the money in the wallet has been entered, in this “Amount to Pay” tab one will be able to see what is the wallet total. and which currency has been selected.

Now let say one buys an item at a store for $21.53. Tap in the white box and enter this amount using the numeric keypad that appears when one taps on the white box. (if you want to put away the keypad without entering an amount, just tap anywhere that is not the keypad or the white box and the keypad will go away).

Once the amount has been entered, tap on the Top Right button called “Show” and a new screen will show with the bills and coins suggested to give to the cashier.

In this screen, in the navigation bar(top blue bar) by tapping on the left button “Amount to Pay” one can go back to the previous screen and one can correct the amount if needed.

In the middle of the bar the amount to pay typed in the previous screen will show. Handy Wallet based on the denominations entered in the Wallet tab, will calculate and give one a suggestion on what to hand the cashier. in this case it found that I have exact change to pay the cashier. I still can decide to use two tens instead of using the one twenty it is suggesting. By tapping once on the minus sign on the stepper under the quantity suggested for the $20.00 dollar bill, Handy Cashier will recalculate the bills and coins to hand in.

In this case it will show two $10.00 bills instead of the 20.00 bill. Once one decides this is the correct amount of money to hand the cashier, tap on the right button called “Hand In“.

Handy Cashier will show the next screen shown bellow this one.

In this case there is no change back. To finish the transaction tap on the Accept key and the “Amount to Pay” screen will show again. Also at these moment the wallet content will reflect the amount payed and the change back entered in the las screen. Which in this case there was no change back.

To illustrate how change back works, a second example follows.

After the previous transaction a total of 46.26 is left in the wallet(one 20.00, two 10.00, one 5.00, one quarter and one cent)  . The new Pay Amount will be 19.11. The amount to hand in is two 10.00 bills. The change back screen will show as follows:

In this case 0.89 is expected back. The cashier has several possibilities to hand change back, so Handy Wallet cannot suggest what bills and coins are handed back as change. Instead it shows only the possible denominations that the cashier will use to give change back and one has to enter the exact change given back by tapping on the “+” on the stepper of each denomination received. In this example I entered 2 quarters, 3 dimes, 1 nickel and 4 pennies which is equal to 0.89 cents. As shown in the next screen:
