The SeedSigner kit comes with most everything you will need to get started, the only pieces you will need to supply yourself are a MicroSD card at least 4GB in capacity and a microUSB cable. Assembly required.

The included blank QR code/mnemonic phrase cards measure 64mm x 89mm These cards feature 24 blank spaces for seed words on one side, along with a warning that reads: "Never enter seed words into a computer that connects to the internet". On the opposite side, there is a blank 29 x 29 QR code grid with room for the wallet fingerprint and some notes, along with a warning that reads "Never scan seed QR into a computer that connects to the internet".

Alternatively, one can opt to use the stainless steel version of the QR code backup. The stainless steel plates are made by @SeedMint21. All of their high quality products are available at https://vulcan21.com/.

The SeedSigner stainless steel plate features a 3mm x 66mm x 91mm plate that can withstand fire and flooding. This is a great alternative from paper because it candle extreme environments. The plate featured in this guide has the SeedSigner logo on it, future plates may not have this logo to help prevent revealing that this is a Bitcoin related product. There is a 29x29 QR code grid on the plate and you can mark the indentations with a marker, check that it works, and then stamp the marks with a punch to make them permanent. The back of the steel plate has a unique number on it.

You can set the SeedSigner kit aside for now while you prepare the software image on your MicroSD card in the next section.
