바 코드 심벌로지 특성의 비교 분석

Abstract

Recently, application scope of bar-code is extending widely. At the department store, convenience store and general merchandising store, there are spreading over introduction of bar-code system and in connection with the opening of market circulation and at the point of where there world be anticipated the adhesion of bar-code to the foreign import civilization, the study made researches and analyzed by drawing out symbol’s entropy and density and compared mutually the characteristic between KAN, DUN, which are using in the country and with UPC, EAN, CODE – 39, interleaved 2 / 5 and NW – 7, which are widely utilizing western countries.

KAN/DUN, UPC, EAN codes that are delta code managing under the EANA system are utilizable only numerical value data and the length of symbol also fixed, so that we can realize that it will become point of an issue at the information’s application field, as well as, restrictive for only POS use.

But interleaved 2 of 5 code, NW – 7 and Code – 39 of width code are able to cope with actively for information’s expression due to they can use not only numerical value data, but also can use special letter and the length also the delta code is fixed, while width code is utilizable variably and we can realize that this is widely utilize in the industrial world.

And that the result that we have calculated the price value of entropy and density of Bar code that already had studied the width code can acquire effective numerical value data than delta code. While as a result that made comparative study of merits and demerits of KAN code, which adopted and is utilizing in our country since 1988, the KAN code, which under administrative control by EANA is making the best utilization for effective use of administrative system and support and discrimination of commodities of EANA which is bar code discriminating organization in Europe, but owing to the restriction of data utilization limit of expression method and unification policy of bar code which is applying separately in the industrial field so that the thesis suggested for the further examination would be required to convert Code – 39 of width code, which is utilizing actively by American industrial world.

While as a result that made comparative study of merits and demerits of KAN code which adopted and is utilizing in our country since 1988, the KAN code, which under administrative control by EANA is making the best utilization for effective use of administrative system and support and discrimination of commodities of ENNA which is bar code discriminating organization is in Europe but owing to the restriction of data utilization limit of expression method and unification policy of bar code, which is applying separately in the industrial field, so that the thesis suggested for the further examination would be required to convert Code – 39 of width code, which is utilizing actively by American industrial world.
