Hi can rf be used with package shipping

Which reader are you using?

Hi

Why did you stop making rfid videos?

This is new world order globalist level crap. Watching everything you do, tracking everything you buy and placing you under constant surveillance. Walmart wants to be the premier retailer of the new world order, nobody else. If you are the only supplier, then the flow of life essentials become much easier to monitor and turn off for people you dont like. Walmart is pure evil. They salivated at the opportunity to participate in operation jade helm 9 years ago. Just evil.

Wow! Thank you. I’m building an RFID application right now and this is exactly what I needed.

Completely confused and a complete novice. How do you get the data onto each label that says, for example, "t-shirt, red, size medium" ? Or am I thinking about it in the wrong way.

Just another way Walmart is passing costs back to the supplier. Then that comes back to Walmart with a cost increase. Then to the customer with a retail increase. Leading to revenue growth and more data points to sell back to suppliers in Luminate charter version.

seriously, whats with the music?

Dear what you want to say about RFID chips used in industrial ink jet printers.

👍

Hey Colynn, are you still active on this channel?

What tag would you recommend for cloth nappies that will be washed for hours at 60 degrees centegrade?

Muy bien, gracias!

Thanks for the sharing. Can you explain a little more on the backscattering? As far as I understand, there are two states in UHF RFID chip, absorbing state and reflecting state. I suppose the chip will stay in absorbing state until the transponder sensor (or receive) enough power to wake up the chip, then the transistor will be "on" and the chip will be in reflecting state. So backscattering happens when the chip is in reflecting state, my question is that does the transistor needs to be "on" and "off" (i.e switching between the two states), to modulate the return signal? or the transistor just keep "on" (i.e. keep staying in the reflecting state) and so the chip can transmit signal back to the reader? Also, how the Radar Cross Section (RCS) affect the return signal or return read range? How the chip knows when to be back to the absorbing state? Moreover, as there is chip sensitivity, reader sensitivity, reader EIRP, etc. It is better if you can show us an example with some values, say EIRP = 30 dBm, reader antenna gain = 6 dBi, reader sensitivity = -75 dBm, UHF tag antenna = 2.15 dBi, chip sensitivity = -20 dBm ... and together with the backscattering and RCS. Thanks

Can you attach an RFID to a plate so that you can track plate inventory?

Thanks! Great explanation!

감사합니다. 많은 도움이 되었습니다!! 설명을 정말 쉽게 잘해주시네요.

This may be a dumb question, but if you were using a linear reader, could you just perform two passes, one in a vertical orientation and one and a horizontal orientation? Orientation? And get a better read at a greater distance?

Where can I buy a software? I have a business and I would like to develop my own system so I can integrate with my clients. Thanks

When trying to calibrate using these steps I get an error stating "Write Tag Failed" after the calibration process that starts at 6:40. Any idea what is causing this issue?

Ready for something amazing Itchat is actually Artifact 3 😂😂😊

Great video... thanks for giving clarity on polarization

I want to learn more

I've got prblem doing calibration for tranparent label. Did exactly as the video did, still cant detect the transparent label. Either it says load paper properly or it just keep going and give that same error. Do you have any advise?

Thanks...

Hi, can the unique number of the RFID tag be associated with the name of an object or a photograph of it so that I can then recognize it when reading the tag?

Important missing piece in explaining frequencies as it pertains to UHF RFID: A point of concern is the extent to which particular RFID tags can be read or written in different countries, given their different frequency bands. A person new to the field might imagine that Tags need to be selected that operate on the same frequency as the Reader in order to communicate, just like in other types of radio equipment. This is not really true. A key to this subject is the way in which Tags respond to commands from the Reader: The Tag signals via pulses that consist of switching its antenna between resonating-and-reradiating (reflecting) the incoming signal, and not resonating/reflecting the incoming signal. This scheme is referred to as "backscatter". The Reader listens for these backscatter pulses, and interprets them as a message responding to its recent command. Withing the "pulsating reflection", the individual reflected pulses are bursts of the underlying frequency as sent by the Reader, whether the Reader is operating at 860MHz, 900MHz, 920MHz or 950MHz etc. So whatever frequency the Reader is set to (per the current location), the Tag's response reflects that same frequency, which is obviously exactly what the Reader is listening for. To make this work, Tag's antenna needs geometry that causes it to more or less resonate when it receives signals anywhere in that frequency range. That said, different Tags will, by accident or by design, have different degrees of sharp tuning ("Q" factor). Sharper tuning means a stronger reflection when operating near the center of the tuning range, but weaker outside that range, compared to a more-broadly tuned antenna. So that is a factor that might play into selecting one Tag over another, though in general, Tags intended for UHF RFID will operate at least somewhat across the entire band. If you know the Tags will only be used in one region, you might select a more-sharply-tuned Tag in order to achieve maximum range, it that's important to your application.

Describing hex digits as "characters" is confusing, and needlessly muddles up hex digits with ASCII characters. For example, the value written in binary format as 0001 1010 1000 0101 is the same as the value 6789 in decimal format. You might describe that decimal-format value as having the digits 6, 7, 8 and 9. You would not describe it as having "characters" unless you were describing a text string "6789". When using computer software we are careful to distinguish digits in a numeric value from characters in a string -- certainly in programming, but even in Excel, for example. Extending that point, the value I previously wrote in binary and decimal format we can write as hex 1A85. And just like the decimal 6789, this hex-format value is also not composed of "characters". It has _digits_ 1, A, 8 and 5. And to add a little motivation for those newly encountering hexadecimal: Its use is widespread because in computer systems bits are commonly used in groups of 8 (a byte). Hex digits correspond to bits and bytes in two ways that are convenient: One hex digit communicates the value of 4 bits exactly with no left overs, and two hex digits fit 8 bits exactly. Contrast hex 1A85 where each digit corresponds neatly to each of the 4-bit fields (in the example above), versus the decimal representation 6789, where you have to do quite a bit of math to figure out either the binary or hex representation.

Those with at least a passing familiarity with computing may be confused by this explanation of RAIN RFID Tag memory "blocks". So far as I can tell, "block" is not a term used in RAIN. What RAIN does describe are Memory Banks, and within those Banks, data is stored as Words. There are four Memory Banks: TID (tag id), EPC (or UII; product Id); User, and Reserved (used for things like passwords and locking). Within those banks, there are some number of data Words (varies according to chip), where a Word is defined as 16 bits, obviously equivalent to two bytes, or four 4-bit fields that can be displayed using hex notation as usual. When this video belabors the fact that you have to write an entire "block", this appears to be saying just that the memory is addressable word by word, which is to be expected. What would be quite useful to know is what baseline common features RFID chips are required to have (for example minimum tag id length), versus degree to which those features may be extended in different chip models and are thus the basis for distinguishing one chip from another (and tags that use each chip).

"schematic" -- If you're referring to a particular format, structure or organization of data, the term used in the database and IT realm is "schema". The word "schematic" usually refers to a diagram of some sort, like an electrical or electronic circuit diagram.

Polarization and Polarity are two entirely different concepts.

"decibels per milliwatt" -- this is a nonsensical phrase, and is not what "dbm" means. This video does not do a good job of explaining dbm, and neither does it discuss the title topic, how RFID tags are powered.

On average retailers have a 25% shrinkage rate ( lost , stolen etc) rfid reduces that to about 2%

Thank you! Your explanation is the best I have heard so far.

Found the chip on the left hinge of my laptop screen, Lenovo Thinkpad W510 ( screen from 2010 week 47, what gives ?

May i get your email address

Informative interview. How do I contact you as per my earlier request on expanding knowledge on RFID?

Great interview Colynn! Really enjoy this type of content in this industry!

great info, thanks Colynn and Matt

I've been working at Walmart for two years now, and to my knowledge, we use RFID, especially for apparel because apparel associates use the RFID wand for scanning. Items with RFID technology will have the EPC symbol on them. If you look at the tag on apparel items in our stores, you will likely see the EPC logo.

I appreciate your content. Do you offer training in RFID for someone interested in furthering their knowledge?

Where can I find the information about the Walmart supply chain how it works

really helpful... Great work keep making videos
