Hey,

place all read Barcodes in a 1-D Array and before adding a new one, check if the Barcode is already in the array.

If you want to compare it to the last one scanned, you just have to keep it in a shift register.

You don't change anything. You add what you have scanned to an array. Basic LabVIEW. Have you taken any of the tutorials?
