    What Are the Differences Between RTLS and RFID? 

    RTLS stands for real-time location system. An RTLS is any solution that can tell you where an asset, individual, vehicle or other object is located, in real time.

    RFID stands for radio frequency identification. Many real-time location systems employ active RFID technology. The active tags are set to send out a signal every few seconds or minutes (depending on how near to real time you want the information to be) and antennas pick up those signals. Software then uses triangulation or other methods to calculate each tagged object’s position.

    There are also real-time location systems that utilize other technologies. Sonitor offers a solution that uses active tags that transmit ultrasound signals instead of RF signals. One difference between ultrasound and RFID is that sound waves do not penetrate walls the way electromagnetic energy does. So if you wanted to know whether an object was located within a specific room, ultrasound systems could tell you that. With an RFID system, it can sometimes be difficult to determine if an asset is on one side of a wall or another.

    There are also RTLS solutions that use infrared, a line-of-sight technology that can tell you where an object is located—but if that item is in a drawer or under a blanket, the system will not function. In many cases, infrared and active RFID are combined, in order to provide the benefits of being able to read through walls, as well as more precise location information when needed.

    GPS technology, when integrated in a tag that includes some sort of transmitter (such as a cellular radio) to communicate a tagged object’s identity and GPS coordinates, could be considered an RTLS technology, though most people do not refer to it as such.

    Malaysia Speed Up Implementation of RFID Vehicle Registration System 

    Malaysia-e-plat-vehicle-registration-RFID-blogIn order to curb incidences of car theft and other vehicles-related criminal activities, the Royal Malaysian Police is calling on the government and other relevant stakeholders to speed up the implementation of the smart registration number plate system (e-plat).

    The system will be using RFID technology, an electronic device that uses radio waves to speed up the transmission of communication data for the purpose of identifying, locating and sensing the conditions of objects.

    e-plat will be affixed to metal license plates and serve as an electronic identification card to automatically identify vehicles and to verify whether they are properly registered.

    “With the e-plat, we can detect criminals using fake registration numbers and also prevent cars from being stolen,” said Inspector-General of Police, Tan Sri Khalid Abu Bakar, adding that the same technology is being used in France and Australia in similar initiatives.

    “Using e-plat on all vehicles will help us reduce crime. In addition, data recorded in e-plat will assist police to detect the criminals and location of the car,” he said.

    NFC Helps You to Find Your Pets 

    NFC-identification-tag-pets-rfid-blogNFC Israel has teamed with printing and packaging provider Tadbik Group to launch FindMyPet, an NFC identification tag for pets.

    After tapping the FindMyPet tag for the first time, pet owners can register their contact details then attach the tag, which also comes printed with a QR code, to their pet’s collar. Whoever finds the lost pet can then tap the tag to see the owner’s contact details while an email is automatically sent to the owner with the pet’s location.

    RFID Helps to Locate Underground Infrastructure 

    3M-caution-tape-locate-underground-infrastructure-RFID-blog3M Company has claimed to have developed an effective way to locate the path of underground plastic pipes and conduits, eliminating the need for tracer wire and test stations and the problems and costs associated with them.

    Traditionally a number of techniques have been used, including tracer wires, but these have limitations. They require power to be effective and cease to operate if broken.

    The company said that its new Electronic Marking System (EMS) Caution Tape “uses a new EMS marker technology embedded into a caution tape for installation near or above the buried facility and helps provide continuous path location.” Technology embedded in the tape transmits a signal to a special reader enabling the precise location and route of the pipe or cable to be found.

    3M says the markers require no batteries and there is no need to hook up an external transmitter or search for access points. The markers work independently so that if a section of caution tape is cut or removed, the other markers on the tape will continue to provide accurate location.

    The tape comes in different versions for different types of infrastructure (water, wastewater, gas, telco). Each uses a different frequency to help reduce the risk of accidentally locating and excavating the wrong buried facilities. 3M says the tape can last for up to 50 years.

    In fact, the tape uses RFID technology, which is finding application in a broad swath of industries. If you’ve ever bought a DVD or a book and seen on the back a label with lots of wire squares one inside the other, that’s one type of RFID tag.

    Those wires are an antenna. The bit you don’t see is a microchip and that’s the heart of the device. A reader placed near the tag creates an electromagnetic field that induces a current in the antenna. This current energizes the microchip, which then uses the same antenna to transmit data stored within it. The reader collects and interprets the data.

    RFID technology works only over short ranges. As the distance increase the power that the tag is able to extract from the reader decreases, reducing the power of its transmission, which in turn has to traverse a greater distance to the reader. 3M’s EMS tape is only good for a maximum of 600mm from the surface.

    Active RFID technology is also available, but this requires an external power source, which would neutralize one of the key advantages of 3M’s tape.
