IATA 2 of 5 is still a widely used barcode type, essentially the same as Standard/Industrial 2 of 5 but with different start and stop bars.
IATA 2 of
5
Most dLSoft products generate IATA 2 of 5 when Standard 2 of 5 is selected and the Extra 1 flag is set. Checking the EXTRA1 checkbox in applications, or setting the flags parameter bit DL_FLAG_EXTRA1 (bit 4 of the flags variable) in libraries sets this flag.
IATA 2 of 5 symbols do not use a check digit.
