GTIN
Colloquially, many know GTIN as a barcode, but technically, GTIN is the number found beneath the barcode symbol itself, and can therefore also be used for other technologies such as 2D barcodes and RFID tags.

The last digit of all GS1 numbers is a check digit.
The check digit is calculated from the preceding digits. It is used as a check for both the GS1 number and the barcode.
Therefore, it is important that the check digit is correct - otherwise the barcode cannot be read.
The check digits shall be calculated according to The modulus-10 algorithm
