For those interested in this space, there are a few alternatives as well. In the LF space (125-134KHz, mainly HID / EM4XX and T55 chipsets) the proxmark is a very useful device. It was also used in the recent cloning of Tesla fobs and VingCard hotel badges.

In the HF space, the proxmark performs well - the HydraNFC is a very powerful device alternative, allowing real time sniffing - but is more hands on than the proxmark. The Chameleon Mini is also a great complementary device for easy emulation of HF tags.

Just a head's up - the proxmark clones, and specifically the proxmark easy clones are notoriously poor clones of a system that is already quite temperamental.

If you're in the market, check out https://proxmark.com for licensed distributors of current stock.

To date, the latest version is the Proxmark 3 RDV4, which is incredibly compact. If you combine the Proxmark with Walrus.app, you have a very capable and portable LF sniffing system.

Adam's system (the device in the article) is a great system, and he's a very smart and affable person if you have the chance to meet him.

Full disclosure: I am associated with https://lab401.com, an official distributor of the Proxmark 3.

Not HTTPS-Everywhere friendly and from 2013. Can we get a title-update?

Also, seems you can't buy them and the kickstarter ended[0] back in Sep 2013. Last update on the firmware was Jan 2018[1].

Seems pretty cool and I'd want one but seems to have died, now. :(

YOu can buy it from their site, 80 pounds Stirling + VAT and Shipping: http://aperturelabs.com/tools.html

Pretty expensive, just checked Alibaba and there's some Proxmark clones for 62USD: https://www.alibaba.com/product-detail/Update-PM3-Proxmark-3...

edit: Aliexpress is even cheaper ($42) and is not in bulk (also, the hardware Proxmark design is open source): https://www.aliexpress.com/item/Newest-version-proxmark3-dev...

However the support for those things that are on alibaba, ebay etc. (Proxmark3 v3 Easy) is supposedly going away.

I've just tried to find a page with the reasons about why they're no longer supporting it, but I've failed to find it.

I seem to remember it's something to do with wanting to support the more fancy versions that cos 5-10x more :/

However I can't find the page, so maybe I'm not remembering something correctly.

Very nice. Though isn't the Proxmark III capable of doing LF (12x-13x kHz) and HF (MHz-range) tags?
