Well done. I'm designing neuro-networks and will be using NFC as part of the system and this was very helpful in helping me understand how to utilize these technologies in tandem. I was a trainer in the Navy and by my standards this is a very high quality informational video. Thank you.
Jennifer, that was very helpful and professionally done. I agree that when one starts talking about EAS vs EPC, or EMV vs RFID, it can lead to a lot more detail that is useful to engineers or software developers, but can confuse the general public. With that said, I'd like to mention the business context of the various technologies at a very high level, which may be helpful to SMBs or individuals who want to think about the practical aspects of implementing for issues of tracking, theft control, etc. When looking at criteria that includes flexibility of use, affordability, and return on investment, the technology that stands out for SMBs is clearly passive RFID, due to the new breed of readers that get up to 30 feet of read range for about $1000, and use your mobile phones as tracking devices (iPod Touch for example can be had for $160), enterprise-quality apps for tracking assets and goods and maintaining workflows at low prices, and the latest fixed-reader IOT devices running about $700 each. Thus, for less than $3000, a small enterprise (or even a homeowner who wants to track items for their homeowners insurance), can now get a complete system including mobile reader, fixed reader, tags, mobile phone, and app for under $3000. Only five years ago, such a system would have required an ante of $20K or more just to start. Anyone interested can check out mobile devices from TSL, ASR, Zebra, or Alien, the first and only IOT fixed reader here ruclips.net/video/i2Hb8furNOA/видео.html, and the new breed of inexpensive yet powerful tracking apps at supplyinsight.com.
Nicely done. It is great simple to follow explanation. I am constantly having to explain these three technologies. Fast forward to 2018 and things are definitely converging in use and capabilities.
Kudos for the Video! Sorry for butting in, I am interested in your opinion. Have you tried - Norajon Proximity Packthread (do a search on google)? It is a great one of a kind guide for getting money with paid traffic minus the normal expense. Ive heard some extraordinary things about it and my close friend Aubrey after many years got excellent results with it.
Thank you very much for differentiating what RFID, NFC and BLE. I've learned a lot. But can NFC tags be used for attendance? for timing in and out of work?
Got you. So basically the whole differences here are 'compatibility' issue. Like for example, BLE can only transmit frequencies between 'registered' devices or terminals, if not, no matter how close beacons fall into the frequency range, they won't interact. Just like a neighbor next door can't connect my Air pods to his smart phone, because it's not registered. Whereas RFID as long as two 'things' are tagged, they all interact each other within the given range. NFC, basically a fancy barcode. lol Thanx
Great video, I want to have a permanent solution in my work vehicle so I can see if any tool is missing from within the vehicle. What method would you recommend? I’m an iOS user.
Rfid, you can build one yourself with arduino and get some rfid stickers for each tool. Write your own or find somebody online to write a program to display which tools are out of range. Hardware is cheap, and you can probably get someone to write the code for under a hundred bucks.
@Jennifer Hueber Very informative video Ms. Huber. Do you think that RFID is the best technology for detecting if a movable object is out of range without, alternatively, using some sort of optical or proximity sensor?
Which would mean the tag on the product is an active RFID-tag right? (to be able to send information on a distance >10cm), or uses wifi for that. In any case that would require bigger and more expensive hardware, which would not be used on smaller products in stores. So what am I missing? Are you talking about bigger alarm-type-tags (attached to clothing in some stores for example) that is removed after payment?
Thank you for sharing.. So if we turn off in the cell settings "Always WIFI Scanning", Always Bluetooth scanning", the signal won't notice the cell entering a store? Or if a person has never connected to the stores Open WIFI, and turns on airplane mode will the cell be noticed walking thru the stores doorway where those security bars are set up for merchandise to set them off if not deactivated at checkout?
If you turn on airplane mode, it is still possible on Apple devices to have WIFI and/or Bluetooth enabled (you can google this). If you turn off the WIFI and Bluetooth functions, your device will not be looking for or listening to WIFI or Bluetooth and therefore would not be detecting or detected by WIFI or Bluetooth systems. Those security bars you walk through at the entrance to the store are to detect security/anti-theft tags on merchandise that were not de-activated at the check-out register. They operate on a totally different frequency than WIFI or Bluetooth.
@@JenniferLucille Cant a person turn on wifi after airplane mode it turned on for android as well as apple? I work in retail and they have a few apps they want us to install which I refuse to. You can turn off all the permissions until the app needs to install a update for the app and sometimes depending on the app they could turn back on any of the permissions which some ordinary Joe wouldn't know they would need to be toggled off. And about the towers at the entrance and exit has gone off when the employee brings a row of carts inside once in a while. Weird huh. But then there are many ways to leave without it detecting even with the alarms are on the piece of merchandise...😠
Also, have u seen anything about which phones will be 5g compatible when it's all said and done.. I started with MetroPC and find out they go off the GSM network which has terrible connection and signal strength. Plus it kills a battery quick. I would think it's from the continuas searching for the cell signals.. I used to go thru Straight Talk which I bought the phone for the CDMA network and loved it until I moved into a apartment complex and couldn't catch a signal to save my life..I'm sure all the congestion around the new place is what did it.
That's not how Bluetooth Beacons work. A Bluetooth beacon device is batter powered and transmits a signal at a scheduled interval. The Bluetooth function on your phone (if it is enabled) will detect the signal ("beacon") that it can "hear" and if you have an application on your phone that makes use of that Bluetooth beacon signal - then that application can do something with that information. Bluetooth technology does not work in the space of "seeing what you're doing in your phone". Hope this helps.
You didn't say anything about the RFID chip on my debit/credit card. Can it really be read by someone standing next to me in an elevator with an inexpensive device they bought from Amazon or eBay? Can they drain my bank account with that info?
If you can pay with your credit/debit card without inserting the card into the chip reader or swiping the mag stripe then that card uses NFC (near field communications) to transmit data. NFC card signals are detectable in a range of 2 to 4 inches, whereas RFID card signals can be detected at up to 25 feet away. The chip that is on credit/debit cards today is an EMV chip (not an RFID chip). This chip creates per transaction encryption keys (in the simplest of explanations). It is extremely unlikely that your credit/debit card data could be compromised in an elevator. Hope this helps!
Definitely--thanks! You're the first person I've heard address this question clearly, and I'm afraid the general public is wasting a lot of money on products marketed to that particular fear.
Actually, you are incorrect. EMV stands for Europay, Mastercard and Visa and these chip based credit cards do not utilize RFID technology. These cards must be inserted into a card reader to be used. "EMV chip requires contact. Maybe your bank decided to use both technologies and your card has NFC also, but it is just the same: there is no risk in the information you can gather with a NFC scanner. It's equivalent to physically looking at your card." www.quora.com/Do-I-really-need-a-RFID-blocking-wallet-with-an-EMV-card Regardless of EMV dynamic or static, this is way above and beyond the purpose of the video I published here. My purpose of this video was to explain the basic differences between three different "wireless' technologies which are often confused for one another.
Sorry, but "what is" is more than what we can do with. Near Field Communication sounds more like "do one and just one thing", such as opening a door, or confirm that I pay. No other user intervention than the only one action. Blue tooth can allow user interaction (multiple options, menus, many possible actions) while the "session" is potentially established (such as receiving a phone call in my car, or playing song from my cellphone, etc. while and my car, or my speakers, don't look like "beacons" to me, double sorry.) On the other hand, RFID are, well, much like NFC, since they don't generally imply a user "menu" or "variation" to the single thing they can do in response to the "burst" they can get. So, you see, I still have the problem to see why someone will use passive RFID instead of NFC? is it a question of range, price, THAT is WHAT the technology is, but you focused on what people do with it rather than what it is. Sorry, you use the wrong title, because it is mostly out of focus of WHAT is the DIFFERENCE between the various technologies. Not useful. Should keep on the focus of the title, or advertise that this is a list what people do with each technology.
By the way, NFC is an extended RFID and can do whatever chain of commands that you program the "chip" with, such as: if my cell phone come close to you, dim the lights of the house, start the car remotely, set my cell in travel mode, and set the house alarm on in 2 minutes. It is a matter of what the "chip" (that you can program with a chain of commands) can recognize and reach... If none of your programmers can do it, I am available, at the right price ;-)
Something tells me you should make your own video so that you can express your viewpoints. I'm thinking of changing the title of the video to "Cute puppy rolls down the hill at the park", would you be ok with that? :)
From your video, all we know about NFC is that you think that it is almost only used to open doors. Well, while hinges and door knobs do just that, pulley, with chains, and electrical motors in some other cases do that too, as for NFC, you have to admit, it is something else. What exactly? your video is much more about the end effect that you saw then one of those technologies is used, then what the technologies are... and their differences. And just to add another illustration, since you seem to be more comfortable with the use over the "what it is", while most recent cell phones do have NFC hardware, not much of them are use to open any door, no? So, what is the use for NFC in those cells phones?
I'm not interested in making an all encompassing video on all the things NFC can be used for. My goal was to describe a few different potential use cases for different "wireless" technologies that are often confused with one another. Again, I look forward to the video content you create for RUclips as you appear to have a masterful grasp of NFC/RFID technologies.
There is already a great article, not by me, about the different wireless technologies, their pro and con, their comparison, and their actual use: www.link-labs.com/blog/complete-list-iot-network-protocols, there is no reason for me to do another one, or a video about it. Note that the difference between technology and protocol is that the technology is generally about the material itself while the protocol is about some agreement in how to use the hardware in order to communicate, but that is just one part of the story. As example, NFC with a magnetic card and NFC with a cell phone, that is the same NFC protocol, but an important difference is the use in that the cell phone being "intelligent", well, more than a magnetic card can be, the "reaction" of the cell phone to the NFC "ping" can be much more versatile. So the protocol is of marginal importance, in the end.. unless you are a technician.
Is there a need to have something block a thief from stealing our credit card information from our wallets? If so, what would you say to look out for or is there something we can do ourselves to prevent it? It is the season unfortunately.
If your credit card is simply a chip enabled card and does not have a contactless payment method, then you do not need an RFID wallet. If your credit card has a chip in it and you insert it into a chip reader to use it, that is not something that can be compromised wirelessly in the same way that an RFID chip could be. I hope this helps!
@David Heller If you read Revelation 13: 16-17, the RFID chip appears to fit the criteria to be used as the Mark of the Beast. RFID chips allow people to buy and sell, and it can be injected into the hand instead of being embedded in a card. That's why some people think it is.

Often merchandise is tagged with small RFID tags so if the item leaves the store without being deactivated at the register, the alarm will sound. There are usually metal pillars at the entrance of a store - these are the RFID Exciters. They emit a signal designed to cause the RFID tag to "chirp" and if the tag chirps, it has not been deactivated (the item was not purchased at a cash register and deactivated) and therefore a security alarm is triggered. Make sense?
Jennifer Huber some articles were saying that these tags on Victoria Secret bras were being used in sex trafficking operations to track individuals for victimization. Any information as to whether this is a likely event, or just circumspect?
@@carolgrayson3542 If there were a tag on a Victorias Secret bra that was capable of tracking a person - it would most likely be a GPS enabled tag. GPS enabled tags are larger than a box of matches, need a battery source and would also need clear line of sight to the sky to make contact with GPS satellites. It is not possible to use the RFID tag Victorias Secret uses to prevent theft of items - to also track a person wearing the bra. If a tag were added to the clothing after purchase for tracking a person purposes, it would still need a battery source and would be quite obvious that it was not part of the store bought clothing. It seems very unlikely to me that this is a plausible scenario.
This video is incorrect and mis-informative about the excitation of security tags for theft prevention, almost all of these tags do not contain any RFID Components, the Square Coil Patches are resonant tank circuits and operate ~13.8MHz, if they are not blasted at the till, it interferes with the resonance of the gate and triggers the alarm. The larger plastic tags, just have a coil and capacitor in them. The lower frequency systems use a special type of metal and a magnet. These devices are resettable with an AC field. None of them are RFIDs. Hope this helps.
RFID is an accurate term to use for the anti-theft stickers used on retail products. I thank you for your input, but you’re splitting hairs. www.explainthatstuff.com/rfid.html
I am sorry but you are WRONG and you link me to an site that confirms what I am telling you. It make a clear distinction between RF and RFID. Its not splitting hairs, EAS is not RFID. RFID stands for Radio Frequency IDentification. EAS tags have no Silicon or ID. As a Senior RF Engineer, working with these technologies I know what I am talking about. Please go and research it. The rest of the video is not bad and clearly presented.
I depends on who you are targeting your videos at, for the general Jo, who does not care anyway, or the future engineers of our world. A good engineer would care about this kind of detail as it is important. But for all the up and coming engineers out there, you are mis-educating them. Why go to the effort of make the video in the first place, if its not accurate. It doesn't reflect well on yourself. but your presentation, effort and intent is good. We will have to agree to disagree, but respectfully, your are still wrong...

Very informative video Ms. Huber. Do you think that RFID is the best technology for detecting if a movable object is out of range without, alternatively, using some sort of optical or proximity sensor?
what is the RFID reader used at shops called? the tall towers which has ads on it?
That's typically called an 'exciter' because it causes the RFID tags to 'chirp'.
Which would mean the tag on the product is an active RFID-tag right? (to be able to send information on a distance >10cm), or uses wifi for that.

RFID is an accurate term to use for the anti-theft stickers used on retail products. I thank you for your input, but you’re splitting hairs. www.explainthatstuff.com/rfid.html
I am sorry but you are WRONG and you link me to an site that confirms what I am telling you. It make a clear distinction between RF and RFID. Its not splitting hairs, EAS is not RFID. RFID stands for Radio Frequency IDentification. EAS tags have no Silicon or ID. As a Senior RF Engineer, working with these technologies I know what I am talking about. Please go and research it. The rest of the video is not bad and clearly presented.
I’m not going to argue with you. I think it is splitting hairs, you don’t.
I depends on who you are targeting your videos at, for the general Jo, who does not care anyway, or the future engineers of our world. A good engineer would care about this kind of detail as it is important. But for all the up and coming engineers out there, you are mis-educating them. Why go to the effort of make the video in the first place, if its not accurate. It doesn't reflect well on yourself. but your presentation, effort and intent is good. We will have to agree to disagree, but respectfully, your are still wrong...
Don't forget this information is useful to future thieves ;)
ALL OF THIS TALK, DOESN'T SEEM TO REGISTER IN MY MIND. ....IT ALL JUST SOUNDS LIKE ELECTRONIC TYRANNY, TO ME!...
