LPC4088 Closed Payment Loop Demo - Running the demo

 

Directly after programming the FLASH has finished, or after power-up, the demo is ready to use.

 

The following screen will be presented:

In order to use the demo, first the Mifare Classic card must be initialized. This can be done by holding the card in-range of the RFID antenna and pushing the center button of the Embedded Artists base-board. If successful, a confirmation message is shown for half a second.

Next, credit must be added to the card. This is done by again holding the card in-range of the RFID antenna, but now pushing the joystick to the top-position (towards the edge of the board). Every time the joystick is pushed to the top-position, $10 will be added to the card. If successful, a confirmation message is shown for half a second after pressing the joystick. The credit can be queried by pressing the "Query Card" button.

Now that the card is initialized and charged, products can be purchased. By pushing the product-buttons in the 3x3 grid, products can be selected. Every time a product is selected, it is added to the listbox and the total cost is updated. Upon pressing "Checkout", the credit available on the card is read-in, the total cost is subtracted and the new credit is written back to the card. A confirmation of this action will be shown.
