Note: the address on his business card and the mentioned website (Transak.info) is fake; there are 294 (empty) companies registered at the mentioned address, and transak.info wants you to believe that he works for the company Transak.com, which is also fake (on one of the pages of the real company's website, there is also a reference to transak.info as an attempt to mislead you with the good name of Transak.com).
Once again, you have been warned and if you want even more certainty, I have a tip: Search online for a second opinion, for example via ChatGPT with the question: 'What is known about Qfron Firm (or Blockchain.com) and is it possible a scam?'
