Introducing Virtual Credit Cards

Experience a new level of security, convenience and control for business: Virtual Credit Cards. At no additional cost, create 'single-use' virtual credit cards to pay suppliers or give to employees through an RBC Commercial credit card program.

A few cards that I read about.

RBC virtual card, seems to do what I need.

Robinhood Gold Card, only in the states.

Wize, not sure if limits are available.

Context: I recently purchased a hotel stay where a merchant charged my card, refunded the amount, and them charged my card a higher amount, all in a few seconds.

Edit: I found Wise provides limits on their virtual cards. I have yet to test how this works and if the transaction is declined for Insufficient funds.
