This lesson uses made-up values. BarcodeBench checks the text received, not the physical print quality, ownership or correctness of a shipment.

## Read item and lot fields without changing them

   Start a temporary session. Values stay on this device and are not sent for a remote lookup.

2. **Enter an item and lot example**

   Enter the complete bracketed example. The digits at the end of this lot stay part of the lot, not an invented expiry date.

3. **Choose how to read the value**

   Choose how to read the value.

   Move to the format choice before asking BarcodeBench to explain the value.

4. **Choose GS1 data in brackets**

   Choose GS1 data in brackets.

   Choose the format that matches the data you are checking. BarcodeBench keeps the original value.

5. **Read the item and whole lot**

   Read the supported fields. LOT17271231 is the whole lot value. Supported checks passing does not certify the product or label.
