Chapter —RFID Tag Formats<br />

Uniform Resource Identifier (URI)<br />

A standardized method to write to a tag is provided by the EPC standard<br />

to simplify encoding of tags. The URI (Uniform Resource Identifier)<br />

representations for EPC tag formats contain just the fields necessary to<br />

distinguish objects from each other, and are included in the tables above.<br />

In order to use the URIs, the tag format "EPC-URN" must be previously<br />

specified by the TAGFORMAT command. EPC is a namespace in the<br />

Uniform Resource Name (URN) encoding scheme.<br />

Example 10 TAGFIELD "@EPC"<br />

20 TAGFORMAT "EPC-URN"<br />

30 TAGWRITE<br />

"urn:epc:tag:sscc-96:0.12345678.987654321"<br />

Other EPC Tag Input Methods<br />

While it is recommended to use the syntax described in the previous sections<br />

to write an EPC tag, it is possible to manually write the full length of<br />

the 64-bit or 96-bit chip in hexadecimal format. For this purpose, the tag<br />

formats "EPC-HEX64" and "EPC-HEX96" are available.<br />

TAGFORMAT NUMBER OF BYTES ALLOWED VALUES<br />

"EPC-HEX64" 8 0-9 and A-F<br />

"EPC-HEX96" 12 0-9 and A-F<br />

Examples 10 TAGFIELD "@ID"<br />

20 TAGFORMAT "EPC-HEX64"<br />

30 TAGWRITE "1122334455667788"<br />

EPC Tag Writing Example<br />

10 TAGFIELD "@ID"<br />

20 TAGFORMAT "EPC-HEX96"<br />

30 TAGWRITE "11223344556677889900AABB"<br />

The following example, also available from the EPCGlobal standard document,<br />

is provided to facilitate users who currently print bar codes with<br />

EAN.UCC encoding schemes and wish to include that information in<br />

RFID tags as well. We use a Serialized Global Trade Item (SGTIN) formed<br />

by the GTIN 10614141007346 and serial number 2. The GTIN is in fact<br />

formed by an indicator, company prefix and item reference.<br />

GTIN Indicator: 1<br />

Company Prefix : 0614141<br />

Item reference: 00734<br />

Check digit: 6<br />

Serial Number: 2<br />

This would normally be encoded as an EAN128 bar code:<br />
