GS1 데이터 매트릭스 코드 사용하기

EasyMatrixCode2 is able to find and decode GS1-compliant data matrix codes.

GS1 표준은 데이터 매트릭스 코드의 내용에 시멘틱 식별자를 추가합니다. 이러한 식별자는 쉽고 일관된 방식으로 해석됩니다.

GS1 준수 콘텐츠의 구조는 다음과 같습니다:

]d2[GS1]{Id1}{Value1}[GS1?]{Id2}{Value2}…

위치:

□

"] d2"는 GS1 호환 스트림을 식별하는 문자열이며,

□

[GS1]은 GS1 이스케이프 문자 (0x1d)이며,

□

[GS1?] means that the [GS1] escape character is present there if the previous application identifier has a variable size value,

□

{Id}는 애플리케이션 식별자이며,

□

{Value}는 해당 식별자와 연결된 값입니다.

예제

문자열:

]d2[GS1]10GR-1-GNU[GS1]11180112151901012112345

는 다음과 같이 해석됩니다:

]d2	[GS1]	10	GR-1-GNU	[GS1]	11	180112	15	190101	21	12345
		Id1	Value1		Id2	Value2	Id3	Value3	Id4	Value4

●

The first Id is 10, this means the first value is the batch / lot number whose size is at most 20 chars.

□

Thus, the product has a batch / lot number of GR-1-GNU.

□

As batch / lot numbers are of a variable size, a separator is required after GR-1-GNU.

●

The second Id is 11, this means the second value is the production date which always consists of 6 digits.

□

The product has a production date of 180112 (12 of January 2018).

□

As production dates have a fixed size, no group separator is required after it.

●

The third Id is 15, this means the third value is the “best before date” which always consists of 6 digits.

□

The product has a “best before date” of 190101 (1st of January 2019).

□

As “best before dates” have a fixed size, no group separator is required after it.

●

The fourth Id is 21, this means the fourth value is the serial number whose size is at most 20 chars.

□

The product has a serial number of 12345.

□

Altough serial numbers are of variable size, 12345 is the last part of the decoded string, so there is no group separator after it.
