Using textbox ?

result = CallObj.GetDigits(4, 10, digitstring) -> 4 digits to enter, 10s of waiting time, digitstring as string
digitstring = CallObj.DetectedDigits -> DetectedDigits is to detect the 4 digits enter by the user
Log(" ID: " & digitstring) -> to display the digits


beside using Log , can it be done by using textbox ???

You can set a MAX size, and also MASK the digits in a textbox. You can also trigger it after 4 characters, or use a timer.

Usually, you'd have a button to press when they're done
