So you can't extract the coins from the banknotes, and the only ones that can do this are the the ones issuing those....
It smells fishy, how can you be sure there aren't 5000 notes with the same address ?

Of course you can extract Bitcoin from Tangem Notes, you don't need their private keys for that, just a special signature. The chip cannot import a private key, only create its own unique one. The firmware is audited.
This is a good way of circulating bitcoin since it will bridge the gap between bitcoin and the areas without internet access. But the problem is that if those producers of those bitcoin smart banknotes are going to print notes more than the number of bitcoin they have in store.
Fortunately you don't need to trust the manufacturer the Bitcoin value is inside each Tangem Note, can be verified over NFC and extracted at any time.
Ok, you should really start clearing things on your website and add more details.
Because this one is just adding confusion:

Since indeed coins can be extracted from the banknotes, what is the procedure for doing this?
Second,
What's your business plan?
Your not going to produce all those banknotes and chips just out of goodwill....
Where is the profit of Tandem going to come from?
