There are four buttons on the JAPER Camera Scanner.

The JAPER Logo in the top right corner is a button and opens the Main Menu. If the logo is red then the app has lost access to JAPER Servers. If the logo is purple then JAPER or the Main Menu has been displayed recently.

The On/Off is a button and toggles the light for the Back Camera and Help is a button that opens this web page.

The Cmd is also a button and opens a virtual barcode, JAPER-COMMAND.

Point your camera at barcodes to highlight and display the barcode's value.
 
Our company, Japer Technology, uses smart-device mobiles and tablets to detect barcodes visually and then securely distribute user specific information in an augmented reality style we call JAPER.

The Main Menu allows JAPER App users to validate email addresses, internet domains and mobile numbers.
