Tag 030 - Virtual Keyboard
Simplify supports a Virtual Keyboard Message on touch screen devices. This message displays up to two lines of text at the top of the screen (Title1 field) together with a virtual keyboard.
Title fields should be used in order, starting with Title1. If this is insufficient, Title2 should be used for the additional text, and if necessary Title3. The maximum length of each Title field is 40 characters for the MX915 and 44 characters for the MX925. The maximum length of the formatted input (including any added literals) is 37 for the MX915 and 45 for the MX925.
If the Enter key is pressed, any text entered on the virtual keyboard is returned in the Virtual Keyboard Response.

Format String
Each character in the FormatString field represents the valid input values for that position.
- C – Corresponding character is a literal, which may not be changed.
- N – Numeric value (0 – 9)
- A – Alpha character (A – Z)
- X– Any character
Display String
If literals are present in the FormatString field, the DisplayString field is used to set up the literals for the field display. The FormatString field determines the input format, regardless of what is in the display string. The format string and the display string (if used) need to be the same length, so the display string will automatically adjust to match the format string by padding with blanks or truncating the last field(s). Eg. (with blanks in the Display string represented as X’s):
- Format string: CNNNCCNNNCNNNN
- Display string: (XXX)XXXX-XXXX
This will only allow numeric input, and preserve the literal formatting. The entire display string will be returned to the POS. If the literals are not desired, the POS will need to filter them out.
