After circumventing the country block to add my Glasgow Subway smartcard to a ZoneCard account, I was wondering: what happens to the remaining subway credit on my card if I load a weekly ticket onto it, and I then take the subway?
I’d hope the credit remains untouched during that week, but I thought I’d better check…

Exciting news. I've just pushed a collection of ports for the #OpenPGP Card ecosystem to Codeberg.

Includes:
- openpgp-card-tools (oct)
- openpgp-card-tools-git (oct-git)
- openpgp-card-ssh-agent

I'm currently polishing them for official submission to the freebsd ports tree this April!

A huge thank you to @hko for these excellent #Rust tools!

Hello and welcome to the #nakeddiefriday again. This one will be a continuation of the previous one with the same exhibit but in more depth. :-)

To remind you, this is the unnamed smartcard IC, which I believe was fabbed by Samsung.

Let's try removing some metal from the top. 🧵

And that's about it for this issue, dear friends. A lot of images with not a lot of analysis. I hope that's okay.

As you might have noticed, I have a particular interest in #smartcard chips. :-) And I always appreciate donations. ;-) Whether you send in your old SIM cards or grab some from "gold recovery" lots on eBay, everything is welcome. Or you can also join my Patreon so I can buy them myself.

On that positive note, thanks for looking at my images and I hope to entertain you again next Friday. Have a nice rest of the week!

Greetings and welcome to today's #nakeddiefriday installment.

Today's guest is a smartcard chip, for which I do not know the actual p/n -- only it's die marking: M7690-G1, by Infineon. This came from a SIM card. The chip had polyimide on top which had to be stripped off, hence the damage on some top metal.

Unfortunately, power distribution routing and CMP dummy fill obstructs the majority of the detail. 🧵
