Thru a command picker, you scroll to your command. Press “Action” button to perform your selection.
(Command Picker: “Scanner”) (Camera is required/ Location (as a reference) is required)

A QR-code scanner in AR mode is used for my demo QR codes. Press “Play” at bottom. The app will set up environment for you. There are some of my demo QR codes for your practice. Finally, quit this app to reset this demo.
(Command Picker: “QR Code (AR Mode)”/ “Camera”/ “AR mode”/ “Add My QR code to …”) (Camera is required)

(Viewer Type: “Preview”/ “Text Viewer”/ “Table Viewer”)

Record scanned codes. Please pay attention.

“Scanner”: Message of scanned code with its timestamp, GPS coordinates and code type.

“QR Code (AR mode)”: Message of scanned code with its timestamp. The record(s) are used for your review of practice.

Perform a stocktaking of asset/ warehouse/ IT asset audit with a checklist of asset codes. 
Or the major/ bonus checkpoints in Scout Orienteering are found. Please organise your files of checklist for your activities.

(Viewer Type: “Text Viewer”)

For a simple locked message (QR code) of product ID number, EASY is an option to make a pre-input passcode before scanning a batch of products (for example, in stocktaking). 

(Viewer Type: “Text Viewer”/ Command Packer: “Passcode”)

View/ Export/ Clear history records. (Reminder: QR codes in Photos is not recorded in history except (for ** view **) in AR environment)
(Command Picker: “View History”/ “Recent Location Records”/ “Export History”/ “Clear History”)

View the checklist/ Import or Paste [a list] to checklist.
(Command Picker: “View checklist”/ “Import to checklist”/ “Paste to checklist”)

You can import a list of codes (separated by line break) from your Documents folder or 
you can copy a list of codes / messages from Pages, MS WORD, Webpage or Text File and 
paste them to the checklist. To deactivate the checklist (audit mode), you should restart the app.  
For game playing (such as Orienteering/ Scout Orienteering Camporee), the instructors may send
a text file of to-do-list in each checkpoint to the player groups (iPhone/ iPad with this app) and
they can return their own history records to the instructor thru AirDrop of this app directly 
because the history records have already contained timestamp, GPS information and code type 
of scanned code(s) at the relevant checkpoints without further editing (Note to the orienteering
instructors: please record GPS information of QR codes in the relevant checkpoints first) 
(Reminder again: Scan QR codes in “Photos” will not be recorded in history except (for ** view **) in AR environment).
