Barcode/NFC Scanner Keyboard User Manual V2

The soft-keyboard with an integrated barcode scanner / NFC reader provides a fast and convenient way of scanning bar-codes or reading NFC tags with any application. The scanned or read data appears in the target apps as entered manually by the user, manual typing or voice input are of course still supported.


Android Barcode-Scanner Keyboard

The Barcode/NFC Scanner Keyboard provides an additional input method for your Android device. It offers a convenient keyboard for manual typing (or voice-input) which is extended by an additional key for fast barcode scanning (or NFC tag reading). Inconvenient app-switching or copy & paste is not required. For the target app there is no difference between user input or scanned data - in both cases, the data appears as typed by the user.

The Barcode/NFC Scanner Keyboard offers support for all common input languages. The suitable keyboard layout is manually configured or activated automatically depending on the system language of your handset.

The Barcode/NFC Scanner Keyboard is extremely easy to use and enables you to scan bar-codes/read NFC tags without leaving the target app.

Barcode/NFC Scanner-Keyboard Simulation Rules

Simulation Rules

By the means of so-called simulation rules the user is able to configure prefixes, suffixes (like an appended ENTER) and various other settings which are used to scan a barcode into a specific target application. When transforming a barcode into keystrokes, Barcode/NFC Scanner Keyboard searches the appropriate rule for the current target app. If no such rule is found, it applies the default rule.

  • List of Simulation Rules

    To maintain simulation rules, go to Android Settings -> Language & keyboard -> Barcode/NFC Scanner Keyboard -> Keyboard Behavior. You see a list of predefined rules. Except for the default rule at the bottom each rule is valid for a specific app only. By tapping on a rule you have the following options:

    • Disable rule
      This option disables the selected rule.
    • Enable rule
      This option enables a previously disabled rule.
    • Edit
      Modify the rule settings (see below).
    • Remove
      The initial default rule can't be deleted.

    A new rule can be added with the button Add Simulation Rule. While it is possible to add multiple rules, only one rule can be enabled for a single app or for the default section.

  • Edit a Simulation Rule
    Rule name

    The user-defined name of the rule.

    Applies to

    Specifies the app for which this rule should be applied. If you select All Apps this rule will be a default rule (a default rule is applied only if no other app-specific rule exists).

    Simulation rule Add a Simulation Rule

    Each simulation rule allows the user to add cursor control commands before and after the barcode data. The following placeholders are supported:

    • ${INPUT} or ${I}
      This is the placeholder for the barcode data
    • ${ENTER} or ${E}
      Placeholder for the enter key
    • ${TAB} or ${T}
      Placeholder for the tab key
    • ${DOWN} or ${D}
      Placeholder for the cursor down key
    • ${UP} or ${U}
      Placeholder for the cursor up key
    • ${LEFT} or ${L}
      Placeholder for the cursor left key
    • ${RIGHT} or ${R}
      Placeholder for the cursor right key
    • ${F1} ... ${F12}
      Placeholder for the function keys F1 to F12
    • ${NOW} or ${N}
      Placeholder for the current date and time
    • ${WAIT###} or ${W###}
      Placeholder for a delay in milliseconds
    • ${KEY###}
      Placeholder for a generic keycode - see Android Keycode List for a complete list of keycodes
    • For a complete list of placeholders press the ... button.

    Any placeholder (except for the function keys) can also be used with a multiplier: ${R3} is equivalent to ${R}${R}${R}. Example: To instruct Barcode/NFC Scanner Keyboard to insert the barcode data followed by the enter key use this rule: ${I}${E}.

    Simulation mode

    Two methods for simulating user input are available:

    • All keys at once
      Scanned barcode data is inserted as a single string into the target app. This simulation mode does not support the simulation of special keys like backspace (${BACKSPACE}) or cursor movements (like ${DOWN}).
    • One key at a time
      Scanned barcode data is forwarded keystroke by keystroke (byte by byte) to the target app. This method is recommended if the target app is a browser or an RDP (remote desktop) application.

    If you have problems forwarding keystrokes to a specific target application you may have to add an application specific rule for the app in question. Most likely browser or remote desktop (RDP) applications require the setting One key at a time for correct bar code forwarding.

    Unknown Keys

    If One key at a time is active and this option is selected, any character which can't be mapped to keycodes is forwarded as hexadecimal character codes. This options is useful for debugging.

    Initial Keyboard Layout

    Specifies the initial keyboard layout for this rule. Choose from Letters, Numbers and Symbols in Shifted or Unshifted state.

    Enable Autoscan

    Enable or disable the autoscan-feature for this rule. If enabled the keyboard checks if the content (or hint) of an input field matches a trigger pattern (see below). Whenever the cursor is placed into an input field and a match is detected the scanner is invoked automatically.

    Look for trigger pattern

    The keyboard tests for matches of the trigger pattern with the Input hint (an input hint in a field provides the user with information on what he needs to fill in, the input hint is usually displayed in gray color), the Field content or both (Input hint or field content).

    Trigger pattern

    In order to start the scanner automatically when the cursor is placed into an input field, the input hint or the field content must match this trigger pattern. Enter a fixed text or a regular expression.

Barcode/NFC Scanner Keyboard Privacy

TEC-IT respects your privacy. The app does not log, store or forward sensitive information.

When using alternative input methods, Android displays a security warning as a general precautional measure which must be confirmed during installation. This message is normal and reads something like this: This input method may be able to collect all the text you type, including personal data like passwords and credit card numbers. It comes from the application Barcode/NFC Scanner Keyboard. Use this input method?.
