Consulting on RFID technologies

For ten years ZAutomation has been working on custom projects based on RFID technologies.

Such technologies allow to increase the quality of the processes and to diminish appreciably the errors; the industrial field represents one of the scenarios with greater development, in fact they come predisposed in order to govern the inner processes of production, warehouse and shipment.


RFID technology can find application in logistics as it allows a complete approach to warehouse and shipping logics, automatically tracking the movements through the reader attachment, or through access to the information contained in the database.

In our days the desire to shorten production and shipping times is more and more recurrent, for this reason RFID technology is applied in the production phases, thus reducing errors in delivery control and payment times a warehouse.

RFID is fundamental in the mapping of the warehouse , the search and picking of the goods speed up: in a traditional picking system, the operation is slow and risky, as it is based on the historical memory of the ‘operator; with RFID, on the other hand, the system manages and knows the exact location of the goods in the warehouse, generating a speeded up process, with the transfer of secure and error-free information.

Among the technological features & nbsp; transposed for logistics purposes, chips with & nbsp; increase performance and memory capacity . & nbsp; We have the opportunity to study and create custom RFIDs, antennas, coatings and tags / transponders even with less sensitivity to the physical environment, i.e. liquids and metals, and to spatial orientation.

Less sensitivity to the environment and greater reading accuracy & nbsp; in practical terms, they mean avoiding “false positives”, ie unwanted readings, which are to be considered as an error.

With RFID technology it is possible to design and equip gates with UHF readers, to be used in industrial environments and warehouses close to loading docks, for the management of automatic identification of inbound and outbound logistics procedures.

It is also possible to create RFID gates on production lines to monitor the movement of pieces and products.

Where can such technologies be applied?

RFID is a very popular tool in the industrial field, let’s now analyze the following possible applications, divided by type of use:

  • Traceability – & gt; uniquely identify an entity. Follow the movements of raw materials and semi-finished products on pallets handled by forklifts or forklifts in general .
  • Inventory – & gt; in order to contain the cost of creating inventories. Check for the presence or absence of a tool or raw material inside the cabinets and shelves.
  • Product identification – & gt; traceability of uniquely identifiable objects. Recognition and identification of the components to be machined.
  • Fraud prevention – & gt; assigns a unique label to each object, which cannot be read by unauthorized persons
  • Access control – & gt; attendance monitoring linked to the staff management software.
  • Shipping – & gt; Reading of pallets loaded on trucks through a gate.


SAW-based RFID systems have the inherent ability to measure tag position, direction of movement, and tag temperature; features that are expensive or difficult to implement for standard RFID tags. In addition, SAW RFID tags, can also be read through metal walls (up to a certain thickness), can withstand high operating temperatures, high energy X-rays and gamma ray sterilization.
The SAW RFID tag uses an inherently cheaper chip in combination with a smaller and less expensive tag antenna, which results in a substantial cost advantage over traditional IC based tags.

Main features of SAW RFID tags:

  • exceeds the many limitations of IC-based RFID chips, including power requirements and performance limitations;
  • can work worldwide in compliance with RF industry regulations;
  • is significantly cheaper than traditional IC-based RFID chips;
  • provides a virtually unlimited number of identification codes;
  • Provides a superior reading radius while maintaining precise and high-speed readings.

Operation of SAW RFID system:

The player emits a pulse of radio waves which is converted directly into a nanoscale surface acoustic wave on the SAW chip surface by the IDT (interdigital transducer). That acoustic wave travels beyond a series of wave reflectors to produce uniquely encoded acoustic wave pulses, which return to the IDT. The IDT converts these pulses into an encoded radio response signal that is sent to the reader. The SAW chip works using piezoelectric effect and does not require DC power.
