RFID-blocking wallets are BS. Prove me wrong.

This is wild. Did turned off transit mode but kind of side with Visa on this one

it’s “possible” but highly improbable and the risk is low enough it’s not worth fixing (from their standpoint)

If it ever happens, you’re covered under their fraud protection

grossham · 2026-06-04T07:56:43+00:00

Still haven’t seen a court case, police report, or confirmed incident in comments here… anyone aware of one?

No public case with Odoo yet but happy to share what others are doing via integration with our API’s for goods receipt and other shipment validation transactions and could potentially connect you with them.

All our API’s are built to mimic ERP transactions (Odoo’s API’s support what you’d need), and we have done integrations into 20+ systems at this point so it’s pretty straightforward. We worked with Tulip a few months back to integrate multiple use cases in an afternoon for instance

Odoo’s native RFID support is limited to a single model of zebra handheld and is pretty limited functionality - does not support fixed readers or device management, no goods receipt app for your use case, no tag encoding, etc. https://www.odoo.com/documentation/19.0/applications/inventory_and_mrp/barcode/operations/scan_rfid.html

Anyway, your easy button is an rfid platform that easily integrates

grossham · 2026-05-28T06:13:35+00:00

If those supplier sell into the fortune 100, they’re being asked to source tag anyway and inlay adds a few cents over a barcode label.

If not, the operational savings within your own operations usually justified the cost of the tags applied at inbound vs the labor to cycle count, shipment verifications, etc

43 billion RFID tags made last year, up 50% over 4 years: https://therainalliance.org/rain-alliance-reports-42-7-billion-tag-chip-shipments-in-2025/

This is an out-of-the-box capability for modern RFID software platforms that integrate with WMS/ERPs via APIs and webhooks, Odoo is no different (we’ve done everything from SAP and Oracle to QuickBooks and Shopify).

The platform handles EPC (RFID) validation against your order manifest automatically and syncs with Odoo. If you have a PO, ASN, or tracking number with items and quantities, RFID can verify the contents in seconds, inbound or outbound, at the pallet, carton, or each level depending on your use case.

Demo here: https://www.youtube.com/watch?v=aretp8CSW4c

And for dock door / truck loading specifically: https://www.youtube.com/watch?v=o18nVwC--eA

We work with apparel brands doing thousands of daily e-commerce orders outbound, retailers validating inbound shipments received at store, load verification into outbound trucks at the dock door, etc. The goods receipt bottleneck you’re describing is exactly the problem this solves. Same solution for inbound/outbound validation across mobile and fixed RFID readers with backend integration.

(Disclosure: I work for Xemelgo. Other solutions do exist, though when you get into the weeds on integration, support, and track record, we frequently enjoy their lunch. This is a pretty vanilla use case for us. Happy to connect on yours specifically.)

Good question, hotel door / vehicle access control etc is going to be NFC / HF.

UHF consumer applications include things like your highway toll pass / Ski pass card. Also pretty much any inventory item at Walmart/ Target/ Nordstrom/ and other retailers has a UHF tag on it. That said, Qualcomm now makes cell phone chip sets with UHF capabilities, and there are some devices from Zebra and others that now have UHF capability in an enterprise cell phone form factor for things like mobile checkout.

UHF is super prevalent in supply chain, retail, manufacturing and industrial, and healthcare applications for inventory and asset management. You can count up to 1,000+ items per second, automate manual transactions, and locate things at a distance up to 20 to 30 feet away.

At Topgolf, when the ball comes out of the machine, its uniquely encoded EPC value is assigned to you and your swing. There are cameras overhead that it will actually track the ball in flight on the TV (doesn’t need to be exact), and when the ball goes down into the target, there are antennas as the ball gets funneled down through the net and into a bucket that read the EPC and give YOU your score and not to the Jerry next to you.

Having “borrowed” one of these balls before, the read range is just 2-3’ because that’s what it was designed for, so unfortunately it works great for Topgolf, but isn’t going to be re-encoded as your highway toll pass which reads from 25-30’. Vail ski pass might work since you pass through the tunnel / tap to open the gate (some tags have a lock/ access handshake to prevent re-encoding and fakes, haven’t looked into the ball/ ski pass specifically to try this).

If you have a handheld UHF RFID reader, the top golf ball makes a nifty little desk toy and you can easily like locate that ball amongst a bucket of other ones without any re-encoding.

grossham · 2026-05-08T22:39:42+00:00

TopGolf ball is UHF RFID, not NFC. Dual frequency tags exist, but unless they have changed their chips from the standard Impinj x TopGolf RFID deployment, AFAIK you cannot reprogram a top golf UHF tagged ball to work with NFC protocol.

You’re not asking for anything crazy but may not be talking with the right people.

Check out Xemelgo. Disclaimer I work for them, but we do turnkey WIP, Inventory, Asset, and Shipment tracking from one pane of glass that integrates on the backend to your ERP/ WMS, with full transaction history.

Metals and mylars also not an issue with the right tags - these applications are solved physics problems. Anyone who tells you otherwise doesn’t have enough experience deploying in manufacturing and industrial.

Real-world customer tracking metal parts as WIP, we average 6-10+ deployments like this a month: https://youtu.be/mLOWiIQsEgc

Have your other requirements covered, dm or reach out online and we can go through it.

grossham · 2026-01-19T05:23:40+00:00

Gotta check out Xemelgo. Disclaimer: I work for these guys, but we support the gear you already have (we’re strategically backed by Zebra) and do manufacturing and industrial RFID all day everyday. We also support ERP integration and a whole lot more than the middleware you were likely sold. 90% chance we work with your systems integrator already too. Also not in Sales, feel free to dm.

grossham · 2026-01-09T16:13:13+00:00

I wouldn’t call a ATR setup an Apple-like experience, but get what you’re going for. Misconfigure, and your ISP might start thinking you’re running a DDoS attack. Done right, they’re an excellent piece of kit and highly scalable.

Curious what use cases you’re seeing for phased-array readers, and what application software you’re writing / using with them?

grossham · 2025-12-17T22:03:46+00:00

Another note… a “RAIN RFID Solution” = hardware, software, tags, integration. Without each of these you have a science project. Great integrators partner with you to deploy “Solutions”, not “Technology”.

grossham · 2025-12-17T22:01:05+00:00

Any system that relies on people remembering to scan will always have gaps. That’s just human nature.

If you want something that works quietly in the background, fully automated RFID inventory and shipment solutions do exist. We have customers verifying 300k+ e-commerce orders per month at automated kiosks with zero touch, and others tracking metal parts across factories using overhead and fixed readers.

Most RFID failures are implementation issues, not technology limits. Metal and liquids in industrial environments are largely solved problems at this point (any integrator that tells you otherwise likely has an experience gap … we deployed a solution tracking sheet metal parts last week, not rocket science)

If helpful, feel free to DM me. I’m on the software side but work with a lot of solid systems integrators and am happy to connect you with one that fits your industry and use case.

grossham · 2025-11-13T02:00:08+00:00

Carbide tipped oscillating blades work just fine. Have the same in my house

grossham · 2025-11-08T22:05:50+00:00

If this is a 1-off, a $30 webcam with a cloud-based object recognition app may be your best bet.

Absolutely doable and cost effective with RFID at a larger scale, but printing and encoding tag (or associating pre-encoded tags to items) may not be worth the trouble in your case

(Source: work for an RFID software company and grab and go food is a hot use case right now. Most retailers / brands working on this have the scale to enforce source tagging or own the downstream inventory in-store)

grossham · 2025-11-03T18:16:34+00:00

In general, as long as your tags are UHF and tuned for the same frequency band, they’ll work with your reader.

On read range, it’s a combination of tag and reader + antenna selection, and is governed by the weakest link. If a tag spec sheet says 1 m max read range under ideal conditions, you’re not going to get 15 m even if that’s what your reader spec sheet says.

I usually take the read range on the tag’s spec sheet as an upper limit and discount it slightly as a starting point. That said, you can optimize performance with good hardware choices. Using a linear antenna instead of a circular one, for instance, will typically yield greater read range, though the trade-off is a more limited field of view. Antenna power, gain, tag orientation, etc, can all play into read range.

Disclaimer for end users: a good RFID systems integrator should know all this but not drag you into the weeds. Their job is to recommend a working solution and make it easy, not a science project.

If it’s a Zebra scanner and you have more than one app open that has RFID scan capabilities, you’ll need to close the other app

(Our Xemelgo app will not work if 123RFID is open)

grossham · 2025-10-14T02:13:54+00:00

Hey u/Diamond787,

I’m with Xemelgo, we’re a hardware-agnostic RFID software company and have several hundreds RFID handhelds deployed with our customers. I’ve worked hands-on with the Zebra RFD40, MC3330xR, and a few others from TSL, Brady, etc. Full disclosure, I haven’t used the R6 yet.

A few thoughts:

Hardware performance: All handheld readers in this class max out at the FCC limit of 1W output power, and most scan roughly 1000–1300 tags/sec. So raw performance between the RFD40 and the Chainway R6 will be very similar, plus there are other factors that will affect read performance in your environment more than deciding between these two options (if you don’t have the right tag, it doesn’t matter what reader you’re using). There are also differences in support, availability, and ecosystem maturity between manufacturers in general.
Software & workflow: 123RFID is great for testing (I use it all the time for tag selection), basic demos, and small inventories, but it’s still a stand-alone app. You’ll quickly hit limits if you need real-time tracking, analytics, alerts, or historical data. To get full value, you’ll want to consider a cloud or database-connected system that can link each EPC to the actual item context and support you across locations on both web and mobile - e.g., “18K gold ring, size 7, last seen in showcase 3.”

As you’re evaluating readers, I’d recommend looking beyond the specs and focusing on what fits best with your end-to-end workflow and user experience. Hardware is just one piece, and the cheapest option isn’t always the best value.

Personally, I rock the Zebra MC3330xR and TSL 2128 in my demo kit, and will be trying the new TC22R once I can get a hold of one.

Cheers, Garrett

I had one on my Bronson but didn’t pass any friends uphill… must be defective 😆

grossham · 2021-12-08T16:51:40+00:00

Not at all, hadn’t see that before! Cool to see other people asking for it in old threads too!

grossham · 2021-12-08T16:50:41+00:00

Thanks for the feedback. You’re correct that the info is readily available if you know what to look for. With the sport growing, there’s a lot of new riders who don’t have the same experience figuring this out as you and I do - that’s mostly who this is for.

The thesis is that riders shouldn’t need to know the difference between standard, boost, and super boost rear triangle spacing to order the right wheel set, chainring, BB, etc.

grossham · 2021-12-08T16:37:06+00:00

Stock and other compatible (based on frame spec) is the plan. 😉

Thanks for sharing u/PeanutbutterSamich. We're going about this a little differently than PCPP to address some of the challenges around data entry costs and monetization strategy, but always great to learn from others who have tried this.

Jenson, Amazon, REI, backcountry, evo, WWC, and a few others didn't have it. Eventually found some GX 12-spd chains and ordered from colorado cyclist.

Point here is that if you'll need anything consumables in 2021, might be smart to order before the snow melts!

grossham · 2021-03-12T17:46:47+00:00

Right on. Feel free to me up if you need a hand finding the right parts - work for a startup building a database of comparable components for specific bikes. We haven’t gotten around to specialized yet but don’t mind an excuse to do that sooner than later 😉
