Should I remove my mask when exchanging business cards?

Even during business card exchanges, there is no need to remove your mask.

To reiterate, wearing masks has become common sense during the COVID-19 pandemic. Therefore, there is no need to feel that not showing your face during a business card exchange is impolite.

However, if, in consideration of the prevailing circumstances, you or the other person expresses a desire to see each other’s faces or suggests removing masks during the exchange, it would be appropriate to do so with mutual agreement.
