Is TCS really 0% for the credit card even after 7 lakh limit?

A few weeks ago, I got an email that said that Niyo Global SBM credit card will not have TCS charges even after 7 lakhs. I want to confirm that this is indeed true.

I already paid the tuition fees, and because of that, my seven lakhs is exceeded. So, can I still use the Niyo credit card without any TCS charges?

Does Niyo’s credit card not take TCS at every transaction? Or is it like for every transaction, TCS will be collected and will be returned at the end of the month or something? Please confirm.
