New 2.4GHz RFID Active Locator / Reader launched (Wireless Version)

Excellent Performance for Different Applications
Passive RFID (battery-less) is very popular in logistics for its low cost, however, it is subjective to too many contraints such as liquid and metal environment. Usually passive RFID system requires careful trial testing and tuning, in situations where items are more valuable that you cannot afford missing; and the items maybe not so RF friendly (liquid and metal); plus you want to have a more automated and flexible system; then an Active RFID system should be considered. 

The latest Active RFID system, HKRAR-LX series, consists of a 2.4GHz reader and different types of transponders which actively transmit signals. It have excellent anti-collision ability which scans 80-100 tags per second. Without connecting to network, it can store up to 800 tags information before network is back. The HKRAR-LX series have ability of high speed identification, tracking objects which are moving at speed up to 200km/h. Even the objects are heavy metallic or liquid, the powered RFID tag can transmit the ID back to system effectively. The battery life of tag can run 5-10 years depends on RF settings and models.

High Reliability

Comparing with typical passive RFID systems, HKRAR-LX series have high anti-jamming function in difficult environment where non-friendly RF material is present.
New Wireless Version
The HKRAR-LXRX can work as a Mobile Reader or Data Collector. Now, the reader only requires a power supply from a power adaptor or a portable battery. Through IEEE 802.11b/g, the reader gathers the tag information and transmit to the wireless router, which is a common network infrastructure in many buildings. Once powered, HKRAR-LXRX is instantly connected and become part of the system.

High Flexibility

Without the troubles of the wired network installation, HKRAR-LXRX provides a larger flexibility in designing the data collector locations. In cases such as exhibitions, the booths and area are subjected to change in each events. HKRAR-LXRX can be easily relocated according to all specific situations.
HKRAT-ST1 - 2.4GHz RFID Active Tag
The HKRAT-ST1 tag is using 2.4GHz ISM standard. It provides omni-directional and unidirectional identifications. Each active tag has a LED indicator and a trigger button behind for performing searching function and alert function respectively.
Durable for Different Applications
The HKRAT-ST1 is suitable for outdoor applications as it has IP65 of waterproof. It also applies in a wide range of temperature and vibration suituation.

Less Readers Mean Lower Cost
The HKRAT-ST1 is designed to be low cost by using specially techniques on circuit integration. This integration allows HKRAT-ST1 to perform long distance up to 100 meters. This active system usually outperforms any passive RFID systems in saving cost by reducing the number of readers and installation cost on the same coverage.

Application Examples:

  • Long Distance Identification
  • Locating & tracking
  • Automation System
  • Asset identification
  • Vehicle Management
  • Access Control
  • Warehouse Management

Active Smartcard System for a Golf Clubhouse

January, 2009

LX series active RFID smartcard system has been implemented in a golf Clubhouse for access control. The golf clubhouse emphasises a prestige quality service to every guest in the clubhouse. They want to let every member feels that they are all recognised by all personnels in the clubhouse and to get access to their VIP memeber facilities smoothly by just walking in. Now, the advance membership tag can be in form of key chain, unlike the traditional access card, the tag provides a much longer sensing area for doors and gates, so that all personnels can immediately be notified for the arrival of the VIP guest in advance. The guests have a warmly feeling in clubhouse, thanks to the automatic recognition system in all facilities, and they do not need take out and show old fashion membership card or "beep" the card on reader.

The active smartcard membership provides following special features in the clubhouse;

i) Automatic Door Control:
The Clubhouse installs active reader to control the automatic door. They give the active tags to the VIPs or specific clients. Once the readers recognize the active tag in pocket or handbag, the door will be opened and allow entrant without the trouble of taking out any access cards. It can avoid a person who has no permit for admittance or entry.

ii) Real Time CRM, Customised Service by Automatic Recognition:
As the reader is connected to a database, once the reader induces the active tag, the customer profile, history, preferences and personal information can be shown to the staff. Then they can recognize the clients and provide a better service with more useful information.

When VIPs enter with the active tag, the LED monitor can display some relevant information which may interest the customers. For example, the VIP status, special offers, etc. Also, it can greet the clients and show update information which may useful to them.

iii) Better Security

Active Smartcard system can be easily integrated with client's security infrastructure to ensure a safer environment. For example, when the door will not be opened if it is not in certain time slot, even the client has a valid active tag; the door will be locked according to the setting. It sets a time limited in order to have better flow control. The active reader also records the sign in and out conditions. It can record down who was entered to the room. The record may be useable for other security issues.

Asset management - Active System in Hong Kong Polytechnic University (Department of Electrical Engineering)

June, 2008

Department of Electrical Engineering (EE) is the expertise in Power and Energy Systems, Power Electronics, Machines Drives, Electric Transportation, Environmental and Energy Saving Systems, Fiber Optics, Computer Control and Automation, and Electrical Building Services.

In the laboratory, students will use the device for experiment. EE put the active tag (HKRAR-ST1) to the devices and install the active readers HKRAR-LXRX in the detecting zone for the following purposes.

i) Anti-theft:
The Electrical Engineering Department installs 2 to 3 readers in the detecting zone and has a full coverage in the area. Once the device is left from the zone, the alarm system will be activated.

ii) Inventory management:
The reader can keep tracking the number of devices. It can make sure that the sets of equipment are complete with nothing missing.

iii) Status tracking:
Active reader can recognize whether the device is being used or not. The central system can know the situation of device and how many sets are being used by the students.

Asset management - Using Wireless Active RFID System in Hong Kong Polytechnic University (Department of Building Service Engineering)

December, 2008

Building Services Engineering (BSE) in the Hong Kong Polytechnic University has an enviable reputation for leading edge research. They combine academic excellence with an innovative attitude that responds to community needs and enables them to quickly put together multidisciplinary teams to meet the changing demands of the profession and society at large.

BSE is conducting a research of people flow in shopping mall. We assist them to simulate the operation with RFID equipments. Our active reader HKRAR-LX-RXWF can work as a mobile device. In this case, BSE built 4 detecting zones in the campus. They put one reader in each detecting zone; this locator can show the movement of student during recess time.

This system helps them to analysis the movement preference of students. By using this wireless active system, the installation is more convenience and easier. The system can work under Wi-Fi; the installation becomes flexible and makes the experiment more effective.

The operation of wireless active system is similar to visitor tracking in Hong Kong Convention and Exhibition Centre (HKCEC). The wireless active system work as data absorption agent and perform data gathering.

The new wireless active system brought an advantage in the installation process. It has great flexibility and conduct a more comprehensive experiment.
