RFID Slow acceptance 2017 – Lack of Knowledge and Understanding

Ξ May 11th, 2017 | → Comments Off on RFID Slow acceptance 2017 – Lack of Knowledge and Understanding | ∇ Active RTLS, General RFID Questions, HF High Frequency, LF Low Frequency, RFID News, UHF Ultra High Frequency |

It is now May 2017 and we are still seeing the majority of potential users with no real understanding of RFID  looking for solutions to help their companies.

While RFID has been around for more than 60 years, there is slow acceptance among the user community simply due to the lack of understanding of “RFID’S”. With businesses looking for ways to reduce labor costs and improve efficiencies and accuracy, existing staff are tasked with “learning” about “RFID’s” so they can be the Team Leader for the “RFID Implementation”.

SkyRFID does offer free basic training but that is not intended to make anyone an expert – Novice maybe – But NOT Expert. RFID means Radio Frequency Identification. While I wrote a blog on this in July 2011 – NOTHING HAS CHANGED!  See blog July 26, 2011 directly below.

RFID is not 1 technology – it is multiple types of identification technologies rolled under the RFID roof – they all use Radio Frequency for Identification. They are not interchangeable between the technologies and in many cases some of the technologies used are really outdated for current needs.  125 kHz and 134.2 kHz enjoyed huge success for many years because that was all there was.  Now we have passive and active technologies in several bandwidths that can do so much more for asset management and tracking.  Better security, better results, longer read distances, read/write capabilities at higher data rates and more, but it is not something that you can just “Learn” or be “Taught” in a short time.

If you have a background in computer sciences and wireless technologies then you will be able to pick up the basics fairly quickly, and then you can get into the ISM band that you want to use for Implementation.  Not understanding IC, TID, EPC, FHSS, WiFi, Bluetooth, TCP/IP, Serial, and other common computer terminology – you will have a slower ramp up time. Most of the hardware documentation available is written by parties that already have considerable experience in the technology and the basics are simply not there – you need to be at Novice Level with some experience in using the technology before it becomes easy to even get an RFID reader (Interrogator) working! Not necessarily correctly – just able to read a tag!

People really do not have the time to “Learn” about RFID – it is simply too complex for most and once you have what you need, unless you are going to be an RFID Expert – you don’t really use the knowledge again. That means a slow long learning curve and then nothing. Unless you are prepared to really learn what you need for your application, you have a great chance of failure and frustration. Implementations are not for UN-initiated people to attempt as it will be a maybe OK – not a 100% correct and working installation.

Fortunately for some of the needed RFID solutions, SkyRFID has been working with Cloud Collected LLC of Delaware to provide Plug and Play Turnkey RFID Solutions. Stay tuned for more details on the new Total Solutions as a Service – (TSaaS) to solve the RFID solution problems.

Radio Frequency Identification is Multiple Radio Frequency Technologies not just one!

Ξ July 26th, 2011 | → Comments Off on Radio Frequency Identification is Multiple Radio Frequency Technologies not just one! | ∇ Active RTLS, HF High Frequency, LF Low Frequency, RFID News, UHF Ultra High Frequency |

We are constantly amazed at the questions that prospective users ask when they visit our web site.  While RFID has been around for more than 5 decades it seems many people still have the opinion that RFID is a single technology that uses multiple Radio Frequencies.  Supposedly these different frequencies are used based on the needed read distance between the reader and  tag  and the material that the RFID tag is attached to.

Wow – would that be a lovely world to be in – easy, fast, simple.

RFID technology is far more complex that just multiple Radio Frequencies.  There are the standard ISM (Industrial, Scientific and Medical) band frequencies that were reserved internationally for purposes other than communications.  Generally these ISM frequencies do not require licensing but are usually locally regulated in the bandwidth and power that can be used and any devices used in these frequencies must accept any interference generated in this ISM band.  Outside of the ISM band there are a number of frequencies that may or may not require local licenses to operate.

If we just concentrate only on the ISM band and only on the larger well known RFID frequencies we have the following wavebands – 125~150 kHz ( usually broken down to 125 kHz and 134.2 kHz), 13.56 MHz, 433 MHz, 860~960 MHz, 2.4 GHz, and finally 5.8 GHz. So we have at least 7 wave bands that can and are being used for RFID applications.  Reality is there are 14 bands used – http://www.skyrfid.com/RFID_Frequencies.php – in this blog we are just looking at the commonly known bands.

In addition to the commonly used 7 wave bands; we  have Passive and Active technologies that govern how the tag and readers inter-operate:

Passive Technology – where the non powered equipped RFID tag is dormant until excited by an RFID Interrogator (RFID Reader);

Semi Passive/Semi Active Technology where the tag contains a battery or some other power boosting device so that when excited by a Reader the tag contents can be read;

Active Tag and Reader Technology where the Tag has a power source and can talk/beacon without a Reader exciting it and the Reader can talk to the Tag and change its contents or communication methods;

And finally Active Tag and Passive Reader Technology where the Tag has a power source and can talk/beacon without a Reader exciting it and the Reader only listens for tags.

So now we see we have 7 wave bands and 4 different technologies that can be utilized within the wave band.

Within each of these technologies we also have the following Tag Read and Write Characteristics:

125 kHz – Low Frequency – Usually read only, but can be read and write – usually limited to 10 hexadecimal characters, usually short range almost touch  – but with the right Reader and Tag combination can read over 1.5 meters!

134.2 kHz – Low Frequency – Also usually read only and 15 hexadecimal characters, but many of the tags can be read and write and like the 125 kHz was usually short read range – under 50 cm, but with the right tag and reader combination can easily go over 2 meters.

13.56 MHz – High Frequency – the biggest usage of all bands – and the most complex, no security, some security, DES security, EAS security, all kinds of flavors, mostly read write, several ISO standards, varying read distances, varying user memory sizes, and constantly evolving. For user memory we can go from 64 bits to over 4K on standard I/C’s.  The new Smart Technology can have hundreds of kilobytes of storage and even its own operating system on the tag!

433 MHz – Ultra High Frequency – older band, was primarily Military but is now providing the longest read range of all bands – commonly read only and limited memory.

860 ~ 960 MHz – Ultra High Frequency – newest band – now known as the EPC Gen 2 band – never fully used in any country but parts of the band are used in different countries so that the same tag can be read all over the world – originally designed for end to end supply chain management, now being used for a huge number of passive tag applications. This EPC Gen 2 has a large number of flavors and variations built in to accommodate global acceptance –http://www.skyrfid.com/RFID_Gen_2_What_is_it.php

Within the 860 ~ 960 MHz band there is another band 916 MHz – not well known yet but growing in application usage.  Commonly this band is Active tag Passive Reader with a shorter read distance than the huge 433 MHz read distance but far larger than the 2.4 GHz and 5.8 GHz ranges.

 2.4 GHz – Super High Frequency – also known as the WiFi band – can be WiFi enabled or can be proprietary, but is usually active tag and active reader with a range of up to 100 meters, sometimes more.

5.8 GHz – Super High Frequency very similar band to our new wireless phones!  shorter read distance than the 2,4 GHz band but we can amplify the read range with more power and larger antennas.

For more information on the passive tag Read Write and Memory capabilities – http://www.skyrfid.com/RFID_Tag__IC_Chips.php

So now we know there are at least 7 frequencies and 4 reader/tag technologies that can be used for RFID applications.  Next blog we will look at each of the 7 ISM bands and try to understand their basic characteristics.

RFID Access Control for Offices, residences, nursing homes and more!

Ξ July 26th, 2009 | → Comments Off on RFID Access Control for Offices, residences, nursing homes and more! | ∇ General RFID Questions, HF High Frequency, LF Low Frequency, RFID News |

In past few months SkyRFID has seen a dramatic rise in the requests for and implementations of access control systems for offices, residences, nursing homes, private homes, universities, and other facilities.

We are also finding that the reasoning for these systems is not just for access control but also for safety reasons.  Access control systems not only allow or prevent access to a facility, department, room, waste bin, washrooms, and other access controllable objects; they also provide real time information on who is in the building in case of emergencies such as fire or explosions.

Years ago these systems were expensive complex to install and difficult to maintain.  Today you can now implement a single door access system and then add to it whenever you want and not worry about interchanging access cards or door locks or access readers.

You can built an easy to use access control system with a few components and have a single access reader contain the tag information – with a built in battery back up – in case of power failure, and then you can add more access readers, more doors, remote building accesses, a PC to control all of the access rights and privileges and of course software.  All of these modern components are fairly inexpensive to purchase. DIY (Do it Yourself) software, ready to implement software and source codes for modifying software to your exact requirements are readily available from SkyRFID.

Now for access control you can use 125 kHz or 13.56 MHz RFID technology and have a variety of inexpensive tags that can be killed quickly from the system should you lose an access card or tag. You don’t have to rekey the locks or even issue keys for the access locks! Simply just make the lost key or tag inactive and that’s all there is to it!  And it is real time so the inactive tag can not be used anywhere.  If you do recover the tag you can easily make it active again.  This saves time and money plus you have an automatic audit trail of every access should you ever need it.

Since there is such a demand for these systems, SkyRFID has built several new web pages to educate potential buyers and also display some of the very wide variety of tags, readers, and other accessories that are readily available so you can have your own solution the way you want quickly and easily.

HF and UHF RFID Reader

Ξ May 1st, 2008 | → Comments Off on HF and UHF RFID Reader | ∇ General RFID Questions, HF High Frequency, UHF Ultra High Frequency |

Since we posted the Blog on our 13.56 MHz. (HF) and 900 MHz. (UHF) reader we have had a number of queries asking “Can the reader read both HF and UHF at the same time?”

Unfortunately the two technologies to read/interrogate the tags are completely different.

HF uses Near Field technology known as electromagnetic induction. The reader and tag literally make a transformer for communication and because of this transforming effect the read distance is very short, hence the term Near Field. Once there is a a coupling between the reader and the tag communication is established by the reader changing the amplitude (size) phase or frequency of the carrier wave to get a response from the tag. Since there can be multiple ways to read HF tags a single HF reader does not have the capability to read all HF tags. This is also one of the reasons HF tags are slower to read than UHF tags. HF also has many different encryption/decryption methods and ISO standards which also adds to the read time and makes a single reader possibility for all HF tags almost impossible to manufacture and if you could make one it would be so expensive most companies could not afford to purchase one.

UHF uses Far Field technology known as passive backscatter which is very similar to the radar gun used by law enforcement officials to check vehicle speeds. The UHF electromagnetic wave is partially absorbed by the UHF tag to power the chip and some reflects back to the reader depending on how well the tag resonates to the UHF frequency. While several years ago UHF was Gen 1 class 0 and Class 1 most of this has been replaced by Gen 2 which is a global standard for reader to tag communications. UHF Gen 2 has only two methods or ways to read a tag and that is totally dependent on the surrounding environment at the time of the read request. If the environment is RF noisy then the reader changes its read method to a slower read algorithm that eliminates the surrounding noise. This is done automatically by the reader and since either read speed is very fast users will not even know that the reader changed its interrogation method While UHF normally is Far Field technology, recent developments of small tags for item level deployment have produced the need for the UHF
to also use Near Field technology. Since the frequency is still UHF a change in antenna type is all that is needed to read NF UHF tags. Note that while you can have UHF tags that read 35 feet or more away from a reader Near Field is usually a foot or less depending on the reader power. The biggest reason for the Near Field tag is so that you can use all of the same hardware to read both Far Field and Near Field in the GEN 2 UHF frequencies.

Summary:

Unless a reader has two different antennas it can not read multiple frequencies (or different read technologies); and unless the reader has 2 separate operating systems, etc. in essence two readers contained in one enclosure you can not read an HF tag and a UHF tag at the same time.

RFID Jewellery Tags

Ξ September 10th, 2007 | → Comments Off on RFID Jewellery Tags | ∇ HF High Frequency, RFID News |

Jewelery, watches and other small high value items can be a problem controlling in many stores. Often stores are forced to limit the number of people in the store at one time just to deter theft.

Instead of having to constantly look around to see if your jewelery and other high priced items are still on the shelves or how many people are in the store and where are they, use our new RFID jewelery tags. These tags not only add brand recognition to your already prestigious product line, it also visibly deters theft!

If just seeing the RFID tag is not enough to deter a thief, just let someone pick up one of your tagged items and watch the door lock automatically as the alarm goes off!

 

RFID Jewelery Tag

Never again will someone try to steal from your store! Everyone in the area will know you use a state of the art RFID Theft Deterrent System and only buying customers will be visiting you!

Since these RFID tags are a great deterrent you can spend more time selling and less time looking and watching – sales increase and loses simply don’t happen.
