SATO Worldwide


A Global Leader in RFID Technology
About Us



Phase Jitter Modulation (PJM) RFID is the answer for situations where large volumes of tagged items need to be quickly and accurately identified. On top of providing 100% accuracy, it is especially designed for dynamic situations where items are stacked or stored in any orientation.



100% Accuracy – Guaranteed accuracy for all tag replies

Close Stacking- Our PJM Stacktag® inlets are specially designed so that they are able to be identified, read and written to when stacked closely together

Orientation Insensitive – Our range of tunnel and desktop readers power tags in three dimensions, enabling them to be read in any orientation

High Speed Data Rates - The unique reply system implemented in PJM products enables tags to be read virtually immediately. PJM tags have a command data rate of 424 kbits per second and a maximum effective reply data rate of 848 kbits per second.

Robust - PJM tags have the ability to frequency hop and reply on any one of 8 discrete channels. With 8 discrete channels where one channel is blocked, for whatever reason, there are seven other channels a tag can use to reply.

Anti-Collision - PJM tags use a unique anti-collision method when talking to readers that is at least 10 times faster than all other anti-collision methods and suffers no loss of reader performance with up to 32,000 tags simultaneously being read.

Large Memory Capacity - PJM tags have a 4kbit OTP memory. This is unique as only the very high data rates provided by PJM RFID can reliably use this large memory in extremely large, tightly packed tag populations or in high speed dynamic environments.


PJM RFID Timeline

1985 Two students conducted basic research in RFID at the University of Western Australia
1990 Innovative RFID at 132 kHz was developed during their postgraduate research
1995 First ever successful read and write RFID tag trial between Frankfurt and Hanover conducted by Deutsche Aerospace and Lufthansa using Magellan's LF technology
1996 Magellan moved to Sydney where funding and guidance by Tim Frost saw the invention of Phase Jitter Modulation (PJM) and a focus on HF technology at 13.56Mhz
2001 First HF microchip in production in Japan and the USA
2004 International Standard ISO 18000-3 Mode 2 (based entirely on Magellan's PJM technology) approved by ISO/IEC and published in Aug 2004. (This standard is still current)
2008 First PJM 3D Antennas launched
2010 First PJM Medical Tunnel Readers and PJM Cabinets launched
2011 Initial sales of PJM RFID systems into hospitals for tracking implants
2013 Joined SATO Group and formed SATO VICINITY under SATO Holdings Corporation


About Tim Frost, Colonel (Ret.)


Having worked for homeland safety services in multiple countries as logistic specialist, it has always been Tim’s interest to find better way of tracking things in motion, and naturally he was always on the hunt for new technologies to advance these ideas.

In 1991, Tim Frost met two students from University of Western Australia developing the RFID technology at 132kHz, and since then he has worked over the past 22 years to help guide and finance the development of the technology. After the early years, which he saw the exploration of airport luggage tracking and railway applications at 132 kHz, the decision was made to move the technology to Sydney and to develop new technology in the ISM High Frequency (HF) band at 13.56 MHz .

The period 1995-98, saw a three year period of intensive research and not only the invention of Phase Jitter Modulation (PJM) but also the first 13.56MHz tunnel readers. At this time the company invented and, in 2002, also patented, the stackable tag technology which is now an important part of the PJM technology suite and one of its long term sustainable competitive advantages.

In 2003, under the leadership of Tim, the technology formed the basis of the first IATA RFID standard and also the new standard ISO/IEC 18000-3 Mode 2. This standard continues as the global standard at 13.56MHz today. Soon after, Tim changed his company’s focus to business development on healthcare applications. In 2005, Magellan sold the first 10 tunnel readers into the medical implant market.

In 2010, the company decided to market complete turnkey solutions for PJM customers to provide not only technology and products but also solutions to the medical market. This led, in turn, to the development of numerous software applications appropriate to the unique characteristics of PJM RFID. This software is now a key part of the medical applications of PJM RFID. Strong growth was achieved in the medical implant market based on the rapid take up and expansion of PJM RFID in Australia and New Zealand to both implant suppliers and hospitals. In 2012, PJM technology developed a dominant leadership position in medical implant tracking in Australia and New Zealand with around 80% of implant loan kits being tracked with PJM RFID.

Two directors from SATO met Magellan’s PJM Technology for the first time in 2010 at a trade show. Following which, SATO became the distributor of Magellan Technology for the Japanese Healthcare Market. In Tim’s eyes, SATO was the first major company to truly understand his vision for the technology and truly see that the better management and control of blood, blood products and medical implants would lead to an improvement in overall human wealth.

In 2013, Tim decided to retire and hand over the PJM Technology to SATO believing that the marriage of the PJM technological and intellectual base with the worldwide reach of SATO is ideal and it would quickly achieve his dream of contributing to human wealth on a global scale using the technology he has developed as his life’s work.
