Using RFID with Loftware Label Manager

Hex Result 350001891002E18000000FDA

URI

urn:epc:tag:gid-

96:6289.11800.4058

URI is in the form:

urn:epc:tag:gid-96:GeneralManagerNumber.ObjectClass.SerialNumber

One way to determine the URI representation of your data and how it is formatted for use with Loftware

is through the Loftware RFID Calculator.

1. Select Options | RFID Calculator.

a. On the Encode section of the RFID Calculator, select the desired encoding type.

b. Enter the values needed for the encoding type.

c. Click Encode.

2. Drag the mouse over the Encoded Result to select it, right click, and select Copy.

3. Paste the copied Encoded Result in the HEX Value field at the top of the dialog.

4. Click Decode.

5. To use this value in the URI Configuration, copy the Decoded URI value and paste it as Fixed

data in the URI Configuration dialog.

DoD Encoding Type

DoD tag construct has been added to the Loftware RFID Solution as an option for DoD suppliers who are

not members of and do not intend to join EPCglobal. DoD encoding guidelines are specified in DoD

Suppliers’ Passive RFID Information Guide Version. This link current as of 11/23/2009.

To encode a DoD tag, the following fields are placed in the proper order within the 64 bits or 96 bits of

the tag:

l DoD header value – This specifies whether the data is encoded as a DOD-64 or a DOD-96 tag

construct.

l Filter value – This identifies a pallet, a case, or a UID item. The values are the same for DOD-64

and DOD-96.

l CAGE Code – This is a unique Commercial and Government Entity (CAGE) code assigned to the

supplier by the DoD. To encode the alphanumeric 5-character CAGE code, a simple algorithm is

used. For DoD-64 constructs, it is compressed by truncating the two most significant bits of the 8-

bit ASCII representation of the characters. For DoD-96, an ASCII space char is prepended to the

CAGE code. The mapped values are listed in the DOD document referenced above. The result is

the Government Managed Identifier value.

l Serial Number – This uniquely identifies the tagged item.
