A mobile communication terminal can comprise a housing, a microprocessor disposed within the housing, a display incorporated into the housing, and a communication interface communicatively coupled to the microprocessor. The mobile communication terminal can be configured, responsive to receiving a byte sequence representing a character string containing one or more alphanumeric or non-alphanumeric characters, to encode the byte sequence into one or more bar code symbols having a minimum dimension of a smallest element equaling or exceeding a readability threshold value. The mobile communication terminal can be further configured to display the bar code symbols.
