honestly given how long ago that was I'd not be surprised if everything's completely peppered with chips... one from the manufacturer, one from inventory, one from logistic, one from corporate espionage agent, one from foreign adversary state actor sky really is the limit with these. didn't parmesan put some chips in their cheese too?
Imagine if the crazies were right and the Covid vaccines actually did have RFID.

Sounds crazy but car and truck tires have had RFID chips for years. I assume most people would be surprised by that. https://www.tirereview.com/michelin-connect-car-tires-rfid-2...
Stealing people's tires is a common thing. So add an RFID reader to cars with ALPR gear, and they can see if any tires they come across have also been reported stolen. See, it's nothing but wins for the consumer!

Used to develop readers based on similar UHF chips (868 MHz in EU). They were quite expensive compared to printed bar codes those were replacing. Also large. With (folded) antennas we are still talking about 40*10 mm minimum for the label. You can not use them on metal surfaces. Readers nearby will interfere as it works by EM wave backscattering, unlike NFC which is essentially a transformer (with electric field inte…
I did work with that recently. Did a few cool demos. The tags got cheaper and you can even get tags that are intentionally designed for metal surfaces. Unlike NFC (or barcodes, obviously), you can read hundreds of tags essentially simultaneously. But because the reading is far from being perfectly reliable (one thing we found out is that human body blocks the 868MHz RFID completely, even at something like 50dBm EIRP,…

The most amazing thing about this (and another tiny RFID chip that was on HN recently) is not that you can print them on wafers, but that you can cut up the wafers and handle these tiny dies. Imagine you manufactured sugar, but had to manipulate each sugar grain separately.
If you want the bare chips and not full assembled labels the usual packaging is uncut wafer and cutting out and handling the individual dies is your problem.
This does not match my experience, although I imagine it's true in some parts of the industry. I've seen bare dice usually delivered as KGDs (known good dice -- tested at the individual level, not just the wafer level). These used to be shipped in waffle packs, but I've more recently seen blue tape used for delivery, and going straight into pick-and-place.

In an early example of conspiracy theories that would eventually envelop social media, I actually remember internet commenters pointing to the previous generation of these as supposed "proof" that the government was embedding RFID chips in banknotes to track people (following a blog article by Alex Jones): https://news.slashdot.org/story/04/03/02/0535225/do-your-20-...

If I worked for VISA's marketing team I'd want to spread FUD like this and "XX% of dollar bills have cocaine on them; protect your children with a youth MasterCard!"

Chips being cheap makes sense at the lithography / wafer level because sure, you can stamp out thousands of them at once. But once you need to dice them up, bond wires to them, and package them... how on earth do you do that so efficiently that each chip can be sold for fractions of a cent?
