For optimal system performance RFIDTraxx LLC offers several inlet form factors for the PJM StackTag™
RFID chips. Each application should be assessed to determine the most suitable inlet form factor to achieve maximum
system performance. "Inlets" or "Inlays", also called "Tags", are functioning RFID devices comprising a microchip,
an antenna coil and a carrier substrate. The inlet antenna is either printed or etched on the substrate (plastic film)
and the RFID microchip is attached to the antenna in various ways. Inlets are then further converted into RFID
adhesive transparent labels, paper labels or RFID tokens.
PJM StackTag™
The PJM StackTag™ is unique in its design. It can be identified, read and written to even when tags touch, overlap or
are present in a stack of some form. PJM StackTag™ uses
un-tuned inlet antennas so that tags do not interfere with each
other. A special functionality ensures a reliable read/write operation of any PJM StackTag even when it is buried inside
a deep stack of other tags.
In almost all real-world situations RFID tags touch or overlap therefore, in practice, stackability is essential to most RFID
applications. PJM StackTag™ inlets, due to their unique functionality, are largely unaffected by the presence of metals or liquids,
which would cause serious problems for tags in other frequencies.
Chips
PJM Chips have been designed and optimized for the powerful PJM (Phase Jitter Modulation) protocol (ISO/IEC 18000-3 Mode 2).
The passive PJM RFID chips operate in the 13.56Mhz frequency band which enjoys worldwide approval.
All our RFID chips are manufactured at high volume foundries in Europe and the USA.
PJM StackTag™
The unique PJM StackTag™ is the only RFID chip which can be stacked without the need for any separation in stacks with
hundreds of RFID inlets. The StackTag feature provides a very high robustness against detuning and will reliably work in very close
proximity to other tags, metals and liquids.
