Smartcard options are great, but if you prefer the original SeedSigner form factor and still want smartcard support, this is the answer.
The premium aluminum enclosure you know and love, now with access to the second USB port as well. Connect your USB smartcard readers and turn your SeedSigner into a smartcard-compatible setup 🔐
All shipped units include a free microUSB to USB-C adapter. Same price as the regular aluminum enclosures!

@ozsats256 Hi 👋
I sell these in my store:

I do ship from the EU so depending on your location it might not be that economical for just a raspberry pi board. Feel free to contact me if you need details

The @Seedkeeper_io NFC Chip allows you to turn almost any object into a hidden Seedkeeper. Easily hide your backup in plain sight by embedding the chip inside everyday items.
Combined with a 3D printer, the possibilities are endless 🔥

Check out this demonstration video to see what’s possible:

@saeir_sajadi Hi 👋
Unfortunately, that is not possible. The Raspberry Pi and camera can be reused, but the main display PCB is required, as it includes the necessary battery connector.
There is a transparent enclosure version for the regular SeedSigner Plus with smartcard functionality.
Another beautiful custom build for a customer.
A fully transparent #SeedSigner with smartcard functionality, paired with a complementary mirror gold metal smartcard. This customer will be transacting in style 💪
Want one of these beautiful transparent models too? 👇

Currently includes a FREE metal smartcard! All colors in stock.
It’s finally here. After a long journey we want thank the open source community for progressing to this point. Last year we asked a Noderunner who did a lot of development work on the Seedsigner plus, if he could create a battery version of the device including smartcard.
It ended up being one of the most amazing team efforts where @xmrstreet and @Printer_Gobrrr teamed up to create something that is ultimate for many. 🧵

Here's a quick demo video. The process is fairly straightforward. I'll have some more in-depth videos about these and some other SeedQR plates.
The picture also shows a test plate I made almost a year ago that's been outside in the elements 24/7 and it's still holding strong. This plate is also punched. So if these plates are kept in a controlled environment I'm confident the markings will last a long time. They'll definitely wont suddenly disappear so you can always give them a touch up if you notice one is getting dull.
I'll also have some anti tampering enclosures for these soon
Protect your assets without compromise.

@Enkitek Correct. Comes with a permanent marker. A single push and the hole will be marked. You can also use a punch tool for an even longer lasting mark
