H. Sprague Ackley

Technologist – Intermec

Speaks at ID WORLD on Wireless Identification

Mr. Ackley works for Intermec on projects pertaining to RFID and bar code technology and is the named inventor on many AIDC patents. He has extensive experience in standards development and is a recipient of the AIM Dilling Award. Mr. Ackley is an active participant with current RFID data construct development including work on the EPCglobal Tag Data Standard and SC31 WG4 SG1 ISO/IEC 15962 as well as being a member of the GS1 BarCodes & EPC Interoperability Requirements Work Group. Mr. Ackley developed the 1D Judge which has been the basis for bar code print quality for the last 20 years. He was the chair of the ad hoc to develop a print quality method for DPM (Direct Part Marking) and to build a 2D Judge metrology device. Mr. Ackley has participated in the bar code and RFID technology committees of GS1, AIM and ISO as well as the application standards development groups in the Automotive, Healthcare, Electronics, and Material Handling industries. Mr. Ackley’s education background includes an undergraduate degree from Bowdoin College and a Masters degree in Physics from Stonybrook University.

“Encoding your bar code data in RFID”

Those who are interested in implementing RFID are presented with a baffling array of ways to encode data and none of them seems to be compatible with the data in their existing bar code applications. Many implementations of RFID often find the need to interact with bar code systems which seemingly have completely different data constructs. Finally, many items have both bar code and RFID associated with them but the encoded data is different.

Last year I presented some background on why data encoded in RFID is so different than the way data is encoded in existing bar code applications. I showed that EPCglobal and GS1 had made some steps toward a way to be able to go back and forth between different data carriers with the same data. At that time in the ISO world (i.e. non-GS1 data structures), they were no where. This year I will present an update on the slow progress in GS1 and where the hurdles to interoperability lie as well as startling progress in ISO.

Amazingly, there has been a major breakthrough in the ISO world. Recently, a universal method of encoding bar code data in RFID was finalized. This method allows users of bar code to “drop” RFID into their systems without modification. Said another way, starting with the same data encoded in any data carrier, a standard RFID or bar code reader produces identical transmitted data strings.

This presentation is essential for anyone wanting to try RFID without disruption of their successful and ongoing bar code system.
