### GS1 Validation

GS1 Validation allows you to output separate GS1 application identifiers such as GTIN, batch or lot number, expiration date, and serial number. GS1 Validation also checks the syntax of the symbol for conformance to the GS1 standard.

Omron Microscan is a GS1 Solution Partner with a Certified GS1 Bar Code Professional on staff. This allows us to provide you with the background knowledge necessary to implement GS1 Standards successfully in your application.

To enable GS1 Validation, click the GS1 Validation box in the Decode Tool Settings editor.

The example below shows the Decode Tool's output broken into individual GS1 App IDs.

##### App IDs

App ID output parameters are added to the Decode Tool when a GS1 symbol is decoded, and they are not automatically removed when subsequent GS1 symbols are decoded. Additional App IDs from subsequent decoded GS1 symbols are appended to the original App ID output parameters to preserve any Omron Microscan Link connections that may have been made to those parameters.

Disabling GS1 Validation clears App ID output parameters. This is useful for clearing App IDs in applications requiring that a large number of different GS1 symbols be decoded.
