Using RFID with Loftware Label Manager

l The rightmost digit is the Check Digit, which you may already have or you may have relied on

the label printer to calculate. This check digit is dropped during the EPC encoding.

l The middle 12 digits consist of your GS1 assigned Company Prefix and the Item Reference Code.

The breakpoint between the two varies with the length of your assigned prefix.

Serialized Global Trade Identification Number (SGTIN)

SGTIN is a method of identifying unique items at the unit or retail level as well as at the case and carton

levels.As described in the preceding GTIN section, GTIN is composed of a GS1 assigned Company

Prefix and an Item Reference.The Serial Number, while not part of the GTIN, is part of SGTIN and

assigned to an individual object by the managing entity. The Serialized GTIN (SGTIN) is GTIN combined

with a unique serial number.

Where GS1 barcodes have traditionally been used, the SGTIN specification can be used beyond the Item

Reference right down to the exact serial number of the item.

If you are already printing GS1 barcodes, most likely you already have the basis for forming a GTIN,

especially if you are involved in the Sunrise 2005 Initiative. In addition to the GTINs, you, as the

managing entity, will need to assign serial numbers to individual objects.With this information,

Loftware’s flexible architecture allows you to create an RFID SGTIN code with relative ease.

There are 3 ways to set an RFID label to create an SGTIN code.Each of these methods is sufficiently

different to warrant describing them separately.

l Calculate SGTIN from existing GTIN and Serial Number data.This scenario for 96 bit labels is

demonstrated in Example 3.

l Calculate SGTIN from existing Company Prefix, Item Reference, and Serial Data.This technique

can be used for both 96 and 64 bit tags and is demonstrated in Example 4.

l Send literal SGTIN data (in hexadecimal format) directly to the field (96 or 64 bit).This is

demonstrated in Examples 8 and 9.
