What is a virtual card?
A virtual card is a card number with no plastic, issued digitally and usually locked down to a purpose. This cheat sheet covers how to think about virtual cards and what to check before you pay a hotel with one. The detail is further down.
How to think about it
- No plastic. A virtual card gives you what you need to make payments, without the physical card.
- The controls are the point. Visa says a virtual card can be limited by where, when, for how long and for exactly how much it can be used.
- Single-use is an option. A single-use virtual card can match each payment to one specific invoice.
- It runs on the same networks. Virtual cards process through payment networks like regular cards.
Before you pay a hotel with one
- Load more than the room. Many virtual cards fail at check-in because they're loaded with the exact room amount. Hotels place incidental holds of $75 to $200 per night.
- Expect a card request for incidentals. Even with a buffer, most hotels still ask the traveler for a personal card for incidentals.
- Watch the name on the card. A cardholder name, often the company's, that doesn't match the guest's name is the most common cause of virtual card rejection.
- Set expiration after checkout. Hotels may post charges after checkout, so set the card to expire 30 days after checkout, not during the stay.
Virtual card vs. physical card
| Virtual card | Physical card | |
|---|---|---|
| Form | A digital card issued through a website or app | Plastic |
| Getting it to the cardholder | Can be issued instantly to a mobile wallet | Mailed, with longer lead times |
| Good fit | Low-value recurring payments, like office materials and equipment | Staff who work away from the office |
How it works on Engine
With Direct Bill, Engine pays eligible hotels and invoices the company in arrears, so travelers never front the room charge. The Incidentals Coverage add-on enables cardless check-in for eligible Direct Bill stays, so travelers can arrive without presenting a personal card. Covered categories and limits vary by property, and participation varies by hotel.
