We can provide our own bip38 passphrase protected private key, correct?
With this series the public and private encryped keys are pre printed. The password for the private encrypted key is a random number between 100 million and 500 trillion salted with date and time and printed as a 10 digit HEX number
The Hex password is preprinted on the note and is entered into bitaddress.org to encrypt the private key..... after printing the keys, the note is removed from the printer and the password is checked with whats on the screen a final time . Then and a scratch off sticker is placed with the help of printed landmarks over the password ... then the process is repeated... The 100 Prints plus some over prints took about 3 hours non stop to complete... no keys or passwords are recorded or can be looked up for future verification.
Then a self destructing hologram is used to cover and protect the scratch off... It is then printed over with a tamper evident printed graphics that overlaps the hologram , and onto the paper... making hologram tampering extreamly difficult without detection.
If you are uneasy with using the preprinted key on the note. I suggest funding the address with a few bits to register the note to the blockchain and use the NFC tag... that is on the back with Greenaddress.it's android app for easy login, essential making the Satoshi note an HD paper wallet with an unlimited number of user supplied keys.
This is just one use for the NFC tag. There are many others and even more undiscovered..
Papersafe Satoshi notes are shipped with the NFC tag programmed with Trustpoint's BlackSeal authentication app for anticounterfieting verification... A cryptographic signed message stored on the tag verifies that PaperSafe.org programmed the tag and can not be cloned.
Happy to answer anymore questions.
