New Lockable RFID Tags with Duel RF, and Other New Utility Passive RFID Tags

In this article, we would like to preview a few very unique Passive RFID products that we are going to launch in coming quarter.

These tags are designed for retail industries and aimed for fast & easy deployment for the front-end shop keeper. Some of them, such as Bottle Clamp Lock, have duel RF features, i.e. they have both UHF for inventory management and AM/RF for Electronic Article Surveillance (EAS).

The UHF RFID provides Electronic Product Code (EPC) and user writable memory, it is the best for supply chain management. And AM/RF EAS is used in daily life for shoplifting prevention, they don't have a ID but it works with conventional EAS gates in shops worldwide.

New Product Preview: Valio Gadget Tag

There is a new product line joining our Empress FamilyValio! The first member of this new line, named Valio Gadget Tag (PN: HKRAT-ET02), will be launched soon.

Key Feature 1: Slim and Low Profile Design

Just like applying labels or asset naming plates, any kind of devices can be tracked by our Gadget Tag because of its thin and light design. Not only is the Gadget Tag suitable for large machines, it is also suitable for small electrical appliances like notebooks, tablet computers and even smart phones

Key Feature 2: Tamperproof

When the tamper-proof sensor is triggered, signal will be emitted to the Empress™ Active Reader preventing unauthorized removal of the tag from the device. Gadget Tag also responses to reader constantly by sending out the unique ID to facilitate real time tracking within the monitoring range. 

Properties can now be properly taken care of with the adoption of Gadget Tag. Stay tune for the release of the Gadget Tag!

Please contact us for any sales enquiry.

Introduction of New Evaluation Kit for Tempcorder Series

Our all new Tempcorder Evaluation Kit are now available. All tags in the Tempcorder series and one reader of your choice (HKRAR-EMWF) are included in each kit.

A demo program is included in the kit apart from the hardware. Not only listing the unique ID of tags, the temperature or humidity data will also be listed along with the ID. The program instantly plots the data received from the tag in a line chart, allowing easier and better monitoring of the environment and hence take immediate action accordingly.

More details for the new kit are included in the leaflet. We sincerely welcome any inquiry about our Tempcorder Evaluation Kit.

Please contact us for any sales enquiry.

Applications of Tempcorder Tag Series

In server rooms, tens of hundreds servers are packed together in such a small room. Malfunctioning may occur if any of them is overheated and cause down time of network which could result in huge losses to companies. How can we prevent this problem with Sense Tag (PN: HKRAT-TT02)?

In industrial sites, extremely hot liquid should be under close monitoring. Certain train components would become extremely hot during operation. If such component is overheated, danger might be caused. How can these extreme conditions be controlled and monitored with Extreme Tag (PN: HKRAT-PT02)?

In museums, valuable paintings and statues should be taken care of properly to avoid any damage. In law firms and banks, important originals should also be saved at places with good ventilation. How can we ensure proper protection to these invaluable properties with Moist Tag (PN: HKRAT-HT02)?

More details on all these application with our Tempcorder series can be found in the Tempcorder Case Study:

Moist Tag and Extreme Tag Demonstration

The two new products launched in October, Moist Tag (PN:HKRAT-HT02) and Extreme Tag (PN: HKRAT-PT02), had undergone a series of tests in the Reliability Testing Laboratory to demonstrate their powerful sensing features.

Moist Tag

Moist Tag is a powerful active RFID tag equipped with a digital sensor providing accurate sensing of temperature and humidity.

In our demonstration, three Moist Tags are placed inside the chamber with changing temperature and humidity settings. An Empress Active Reader is connected to a PC next to the chamber. Instant data will be sensed by the Moist Tags and sent to the reader with the tag ID constantly. Data collected on the reader will be processed by the demo program installed in the computer.

Moist Tag is specially designed to be equipped with an accurate humidity sensor of up to 1% RH resolution and wireless functions. Humidity data will be sent to the reader that is connected to the central server periodically, which empowers accurate and timely data for strict environment control and monitoring applications.

Extreme Tag

Extreme Tag is a temperature sensing tag specifically designed to be equipped with an external probe to monitor temperatures ranging from -200 to +500 for environment control or hazard prevention at extreme surroundings. With a separation design for the tag, the tag can be placed at a stable and moderate temperature environment, while the probe can be attached to environment with extreme temperature.

In our demonstration, we placed the external probe of Extreme Tag inside the chamber with the changing temperature, while the body of the tag remains outside the chamber. The Empress Active Reader receives temperature data captured inside the chamber from the tags and such data will be processed by the demo program installed in the PC and presented in a line chart. The gradually changing curve reflects the condition inside the chamber accurately and timely.

How EFDS works? Meter Recorder in Action!

What is EFDS?

Electronic fuel delivery system (EFDS) is an award* winning system that helps you to generate fuel efficiency reports that compares the operation time again fuel consumption for each construction vehicle or machine.  It is a system that combines and automates machine/fleet management together with flow meter recording.

Situation: In a medium size construction site, there are over 50-100 fuel-powered machines or vehicles, having their fuel tanks refilled with hundreds and thousands gallons of oil/diesel every day.


  • It is hard to measure how efficient each machine is. It is hard to obtain their total run time. It is hard to get the amount of fuel consumed too.
  • How could you determine the FUEL EFFICIENCY without all these data?
  • Sometimes, different contractors might work at the same site, using the same fuel refilling station/facilities. If you want to split the bill according to each vehicle and their operation time, you need a lot of paper work.

How EFDS works:

  • Install a ID Tag (transponder) on that machine, so now each machine now has an ID
  • Install a wireless Operation Timer (datal ogger) is connected to each machine's fuse box, the logger records the operation time
  • The flow meter in refilling station are connected to our ES-Box, which records the amount of oil refilled
  • The Mobile Handheld Reader identifies each machine by reading the ID Tag on them as they approach
  • These data can be consolidated and shown on a Mobile Handheld Reader and then print out by a printer immediately

A ID-Tag and Operation Timer are installed on a diesel generator (NISSHA NES220EM) control panel. ID-Tag and Operation Timer can be installed separately in different parts of the machine. Sometimes the fuse box and fuel injection opening of a machine are very far apart. But with our system this doesn't hinder us at all!


A ES-BOX (Embedded System Box) communicates with the flow meter register  (e.g. Veeder Root EMR series), the ES-Box works well with other flow meter register system with RS232/485 or any other kind of communication method.

A Mobile Handheld Reader can consolidate all the data from ES-BOX, Operation Timer and ID Tag to generate a list of machine/vehicle operation time and their fuel consumption record. These data can be shared through mobile network to construction site office or headquarter for record.  

A portable Bluetooth printer is very handy for printing a receipt for contractors or operators to keep record.
