RFID key fobs benefits

Today, RFID key fobs have gradually become an important necessity for car owners because of the multiple benefits that they deliver. Read this article to find out what key fobs are, how they function, what benefits one gets by using them and how they are making a car owner’s life a little easy.

In the past, car key fobs were just simple metallic gadgets that were stamped with the car company’s logo. But with time its usage has undergone a change. Now, key fobs are used for activating remote keyless entry systems on vehicles. Few years back, the key fobs operated with the help of infrared and required a clear line-of-sight to function. Most new models use challenge response authentication over radio frequency and do not need line-of-sight to work. Programming them sometimes requires the automotive dealer to connect a diagnostic tool, but most of them can be self-programmed just by following a set of sequenced steps in the vehicle and generally requires at least one working key.

These days’ Key fobs are being used increasingly in apartment buildings as well as condominiums for access to common areas such as lobby doors, storage areas, fitness room, etc. They usually contain a passive RFID tag. A fob operates much like a proximity card to communicate with a central server for the building.

Mostly, these key fobs are seen to be used by car owners because of their multiple benefits, they are a great help. A key fob functions like any other basic remote controlled system. The computer chip in the remote creates a unique code that the receiver is programmed to recognize. One good thing about this code is that, it cannot be replicated.
Keyless entry is a fairly new thing but is becoming more and more standard as the technology improves. One can actually unlock the car just by being in the vicinity of the car. It gives the option of starting the car without having to put a key into the ignition, as the keyless entry allows for a push-button start.
Key fobs often have the ability of unlocking the trunk. The trunk opens up completely with a press of the button on the fob and allows one to get things in and out of the vehicle with relative ease.

A key fob can certainly enhance the overall experience of using the car. Whether it is an automatic start feature or a trunk unlock feature, one can get the most out of the car with a key fob. This is also a great way to prevent theft and also to incorporate an automatic keyless ignition system in the car. Luckily, car key fobs or even a key replacement can be easily accomplished. It may be as simple as contacting a local dealer for the vehicle’s brand. Even better, one can find an online dealer of replacement car key fobs.
The RFID key fob which is small and nice performance and it is durable. It is easy to take in your pocket as RFID keyring. You can design your own logo and numbers on the RFID key fob. It is water proof , dustproof and durable.

Logistics Management

RFID tags application in Logistics management

what is Logistics management? Logistics management is a supply chain management component that is used to meet customer demands through the planning, control and implementation of the effective movement and storage of related information, goods and services from origin to destination. Logistics management helps companies reduce expenses and enhance customer service.

The logistics management process begins with raw material accumulation to the final stage of delivering goods to the destination.

By adhering to customer needs and industry standards, logistics management facilitates process strategy, planning and implementation.

Logistics management involves numerous elements, including:
*Selecting appropriate vendors with the ability to provide transportation facilities
*Choosing the most effective routes for transportation
*Discovering the most competent delivery method
*Using software and IT resources to proficiently handle related processes

In logistics management, unwise decisions create multiple issues. For example, deliveries that fail or are delayed lead to buyer dissatisfaction. Damage of goods due to careless transportation is another potential issue. Poor logistics planning gradually increases expenses, and issues may arise from the implementation of ineffective logistics software. Most of these problems occur due to improper decisions related to outsourcing, such as selecting the wrong vendor or carrying out delivery tasks without sufficient resources.

To resolve these issues, organizations should implement best logistic management practices. Companies should focus on collaboration rather than competition. Good collaboration among transportation providers, buyers and vendors helps reduce expenses. An efficient and safe transportation provider is also vital to business success.

GPS VEHICLE TRACKING

One of the biggest fears of any car owner is not knowing where their vehicle is at all times.

Just the thought of handing your car over to a complete stranger for several days is understandably spine-chilling. Most people are aware of how a Global Positioning System (GPS) works. It is essentially a satellite tracking device which allows you to know the exact location of a particular place or object.

What we did was combine this useful technology to the auto transportation process in order to insure our customers of their vehicle’s safety. By equipping our trucks with this system, we can get updated positioning coordinates of their location at any given time.

By logging into our online VEHICLE  tracking system, you can receive updated information as well as actual map images of your vehicle’s location. This will assuredly provide anyone shipping their vehicle with peace of mind.

RFID Container tracking vs Satellite Container tracking

One recent article contrasting RFID and satellite tracking for cargo containers raised some interesting points. Unfortunately, instead of focusing on positive aspects of what satellite tracking could offer, it concentrated on making some fairly dubious assertions about the ‘faults’ of RFID. So, what is the truth about satellite versus RFID for Bulk container tracking?

Satellite communications that go beyond mere GPS information can provide information not only about the location of a container but also about its environmental conditions, whether it has been tampered with, and other useful data. What’s more, this can be achieved with in-transit containers virtually anywhere in the world. For some applications, such as tracking of munitions, hazardous materials, pharmaceuticals and other sensitive goods, having access to that kind of information in real time can enable the cargo’s owner to take immediate corrective action (if any is possible). For the majority of supply chain applications, however, access to this type of data at the point of receipt is perfectly adequate.

Misconceptions
The issue isn’t whether satellite communications between a container and a head office can offer benefits in certain applications, the issue is that the article misstates RFID’s capabilities, costs and limitations with the intent of supporting the assertion that, “RFID is not good for global supply chain usage and satellite is good. In fact, RFID usage is actually dangerous for applications in US seaports.” The article’s review of the benefits of satellite is sketchy at best. The major support for its premise is based on a biased and, in some cases, untrue evaluation of RFID.

Technical applications
The article states that RFID cannot be used globally because there is no worldwide agreement on frequencies and hasn’t been authorised for use in countries such as China. While true in some measure, the article overlooks the inconvenient and obvious fact that all major international trading countries including Japan and China have approved active RFID products operating at 433 MHz that are based on ISO 18000-7 standards. The global RF community is moving to authorise the common HF, UHF and microwave frequencies to enable RFID usage around the world. The frequency differences cited in the article apply to UHF, not in 433 MHz active tags. And, in any event, UHF systems are capable of handling those differences.

Infrastructure
The assertion that fixed location antennas might be difficult to place because of legal and operational issues is unsupported in real world application. Yard and port operators are installing various RFID reading systems to expedite shipments in and out of their facilities and to provide a value-add service to customers. Mounting readers on cranes and at certain locations at ground level address many reading needs. Readers on cranes and tugs can also provide absolute linking between container movement and the equipment or operator.

Timeliness & features
It is true that RFID typically works by having goods and containers move past a reader and that RFID data logging and e-seals offer historical data. Satellite can transmit the occurrence of unwanted events in a far timelier manner. In some instances, this can trigger urgent, necessary responses. In other instances, however, having this data go from the container to a head office isn’t a particularly efficient or even necessary scheme. Sometimes, having the container communicate directly with, say, the driver of a truck, is more efficient. If a refrigeration unit on a trailer fails, the driver, not the main office in some other state, is going to have to take corrective action.

ISO/IEC TR 18047-4:2004

ISO/IEC TR 18047-4:2004 defines test methods for determining the conformance of radio frequency identification (RFID) devices (tags and interrogators) for item management with the specifications given in the corresponding part of ISO/IEC 18000, but does not apply to the testing of conformity with regulatory or similar requirements.

The test methods require only that the mandatory functions, and any optional functions which are implemented, be verified. This may, in appropriate circumstances, be supplemented by further, application specific functionality criteria that are not available in the general case.

The interrogator and tag conformance parameters in ISO/IEC TR 18047-4:2004 are:

mode-specific conformance parameters including nominal values and tolerances;
parameters that apply directly affecting system functionality and inter-operability.
The following are not included in ISO/IEC TR 18047-4:2004:

parameters that are already included in regulatory test requirements;
high-level data encoding conformance test parameters (these are specified in ISO/IEC 15962).
Unless otherwise specified, the tests in ISO/IEC TR 18047-4:2004 apply exclusively to RFID tags and interrogator defined in ISO/IEC 18000-4 Mode 2.

ISO/IEC 24791-2:2011

ISO/IEC 24791-2:2011 defines the interface(s) that provide operations on (radio frequency identification) RFID tag data including, but not limited to, reading, writing, collection, filtering, grouping, and event subscription and notification within the Software System Infrastructure (SSI).

Specifically, the interface(s) defined by ISO/IEC 24791-2:2011 provide the following features:

  • full support for the commands and responses for air protocols supported by ISO/IEC 24791-2:2011 at an abstraction level appropriate for Data Management’s position in the SSI architecture defined in ISO/IEC 24791-1;
  • an abstract definition of commands and operations that can be applied to different network bindings and encoding mechanisms;
  • support for the encoding mechanisms defined in ISO/IEC 15962;
  • volume reduction, format or structure modification, data analysis, and data access appropriate for Data Management’s position in the SSI architecture defined in ISO/IEC 24791-1;
  • reporting of data to support application or data managing in formats controlled by the client, either inside or outside of SSI.

ISO/IEC 24791-2:2011 is composed of the EPCglobal Application Level Events Standard, in its entirety, with extensions to further support operation with ISO/IEC 15962 and the air protocols defined by ISO/IEC 18000.

ISO/IEC 24791-5:2012

ISO/IEC 24791-5:2012 defines an interface within the Software System Infrastructure (SSI) that provides RFID system control components with low-level access to RFID interrogators for the purpose of optimizing RFID data access and control operations. This interface is designed to be modular with the ability to support multiple RFID air protocols. However, in ISO/IEC 24791-5:2012, the only RFID air protocol supported is Type C of ISO/IEC 18000-6.

ISO/IEC standards – ISO/IEC 18000-7:2009

ISO/IEC standards – ISO/IEC 18000-7:2009
ISO/IEC 18000-7:2009 defines the air interface for radio frequency identification (RFID) devices operating as an active RF tag in the 433 MHz band used in item management applications. It provides a common technical specification for RFID devices that can be used by ISO technical committees developing RFID application standards.

ISO/IEC 18000-7:2009 is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace.

ISO/IEC 18000-7:2009 defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum power, spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate.

ISO/IEC 18000-7:2009 further defines the communications protocol used in the air interface.

ISO/IEC standards – ISO/IEC 18000-6:2013

ISO/IEC 18000-6:2013 defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz Industrial, Scientific, and Medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards.

It is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace. It defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used in the air interface.

ISO/IEC 18000-6:2013 together with ISO/IEC 18000-61, ISO/IEC 18000-62, ISO/IEC 18000-63 and ISO/IEC 18000-64 specifies the physical and logical requirements for a passive-backscatter, Interrogator-Talks-First (ITF) or tag-only-talks-after-listening (TOTAL) RFID system. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave (CW) RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is ITF, meaning that a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator, or TOTAL, meaning that a tag modulates its antenna reflection coefficient with an information signal upon entering an Interrogator’s field after first listening for Interrogator modulation in order to determine if the system is ITF or not.

ISO/IEC 18000-6:2013 contains one mode with four types. The detailed technical differences between the four types are shown in the associated parameter tables.

Types A, B and C are ITF. Type A uses Pulse-Interval Encoding (PIE) in the forward link and an adaptive ALOHA collision-arbitration algorithm. Type B uses Manchester in the forward link and an adaptive binary-tree collision-arbitration algorithm. Type C uses PIE in the forward link and a random slotted collision-arbitration algorithm.

Type D is TOTAL based on Pulse Position Encoding or Miller M=2 encoded subcarrier.

Types of RFID Technology

When you are researching RFID wristbands, it is important to understand that there are different types of RFID technology. An active tag uses a battery, and only transmits the signal periodically. A passive tag that is battery-assisted also has a battery, but it remains passive until it is within the vicinity of the reader, which signals the RFID technology to activate. The third option is the cheapest type of RFID technology, which is a passive tag. With the passive RFID technology, there is no battery within the card.

The passive RFID cards can be beneficial for an RFID wristband, because it is small which makes it convenient to include it in a wristband. This type of RFID technology is stronger than the other two types, which might impact interference and radiation exposure, so you should consider your priorities when you are choosing the right RFID technology.
