$169 is a bit steep for me, so I went on Temu and bought a $8 125KHz RFID programmer & a $5 USB-C IR Blaster. Combined with my Samsung phones native NFC writing, bluetooth, etc I feel like it scratched the itch of 90% of what people do with Flipper for 10% the cost.

I was thinking the same. It's a proven predatory and reckless company that can sell at these prices because of shady practices. But hey, savings!
I’ve had one of these guys sitting around for a while - love the hardware, love the concept, but I haven’t really found a lot of use for it - what are y’all using them for?
I'm not competent of interested enough to make full use of them but I get the impression that they still have a lot of use in a large part of the world where simple RF is used to open gates and garages.
And of course you can copy and store RFID but you still have to get your hands on the tags. And that's where it falls down in certain more developed countries because they've mostly moved to RFID.

If you want to go deeper with RFID and can spend a bit more (~$50), I am pretty happy with my knockoff Proxmark3 Easy [0] I got on ebay. (Do some research to find a good seller as I have heard some sellers ship bad units). It can do both 125khz and 13.25Mhz RFID/NFC and is easier to use then some of the Android apps for cracking Mifare keys. For the price, it is great for more complex attacks and almost has all the f…
Do you have any resources for learning about RFID? I have some tokens for opening my garage door that I'd like to clone, and I'd like to know how they work.
To get started, the basics are: low freq (LF) is usually around 125khz and is rarely encrypted (HID Prox is the most common in the US). The data is often encoded in Wiegand format for access control systems (something to keep in mind when reading the raw data).
High freq (HF) (aka NFC) is ~13Mhz and is readable by most Android phones with NFC. Not all tag data can be read however. HF cards support a lot of different options including data storage (normally in a block layout with permissions to read and write depending on keys) and encryption (iCLASS and SEOS being the HID offerings and very common). Some can be cloned (like hotel cards) while others (like SEOS) require a downgrade attack to work correctly (SEOS -> normal SEOS reader -> Weigand data -> older style card like HID Prox).

I would check out the Proxmark3 Github repo [0]. They have a cheatsheet [1] with the basics on how to get started. I also did a talk about RFID security last year about the basics [2] To get started, the basics are: low freq (LF) is usually around 125khz and is rarely encrypted (HID Prox is the most common in the US). The data is often encoded in Wiegand format for access control systems (something to keep in mind wh…

Same! Pretty handy to have all amiibos in a single place, and quickly iterate through them.
You can likely use your phone. There’s some apps designed for it specifically.
