What if there is no defined time frame? If you can buy minutes in the form of a pre-paid card, why wouldn't it be property? You could resell it. And it's a "pre-paid" card, not a "minutes contract". That makes it see that it is a stored cash-value card. The only difference is that the value is removed from the card in proportion to calling minutes as opposed to dollars spent.

What about the case of airline points? Those are used almost interchangeably with cash. Hell, didn't American Airlines pay Citi in points once?

Every pre-paid card I've seen has in the fine print an expiration date. If there are some that are totally open-ended, that does change the argument a bit.

Those expiration dates are quickly becoming illegal. I don't know how it applies to pre-paid minutes, but for gift cards, most states have eliminated expiration dates.

I don't know about other systems, I use a Tracfone, and while I have to buy a new card every 3 months, the minutes roll over - I'm up to over 7 hours now.
