I'm looking for a word or expression for a short term license for an app. Users will pay for a license to use the software for a couple of hours or days. I have considered some words but none seem to be perfect. Here are the main ones, and reservations I have about using them:
This seems to be the "correct" one, but is usually associated with a perpetual license. And therefore "3 day license" seems a bit like a contradiction, and is also a bit wordy.
Code / ID
While this is how it's implemented, and appeals to me as a software developer, it doesn't seem to describe the actual "item" being sold.
While I think this conveys the idea correctly, it seems to be a little slangy.
Permit / Ticket
Refers to a nonexistent object. Also see "Code/ID" above.
Usually means recurring.
