Printing or Imprinting Tags, Labels or directly on the product is a side business for QDX DLT Blockchain. Main business will be getting adoption of QDX DLT Blockchain which will immutably register the Tags in the blockchain so they can't be counterfeited. Unlike algorithms, QMC does not use cryptography to register the Tags and therefore cannot be hacked. I have no proof of this other than what I read in my DD and interpretation of what the company has stated. FWIW!

I don't think companies can buy QD tags without signing up to license the blockchain.
The tags are a distinct unique distinguishing proposition that makes the blockchain more valuable. Licensing means continual fees or SAAS, valued by either the value of the merchandise being protected, the volume of the products, or the number of transactions, users, or smart contracts.
