You can create physical cards with custom employee names. There is no limit to the number of physical cards you can create, there is only an aggregate limit on your account of the number of combined physical and virtual cards you can create.
The account below, for example, has a 1500 card limit. Of those, 1500 could be physical, or 1500 could be virtual. In aggregate there just can't be more than 1500.
To create a physical card:
Visit the cards page by clicking the card icon in the side panel.
Click on "Add +" on the top right of the dashboard
Click on "New Card"
Click on "Physical"
Type in the employee first and last name, and the address where you'd like to have your card shipped.
Done!
When your card arrives in the mail, you'll have to activate it by:
Clicking on the card you created inside the cards page
Typing the last 4 of the card into the Slash dashboard
