This is one of the most exciting projects in the freedom tech space

Do you have an internet connection? You can sell it for sats on a time or packet driven basis

The buyer (who is offline) simply pastes a cashu (ecash) token into the captive portal. The portal claims the bitcoin, then provides the (vpn protected) access.

In a future where internet connections are KYC'd or otherwise difficult to get (ie, require a sim card to dox your location) it's great to see tools that allow end users to easily get online.

How does an offline user generate an ecash token when internet is required to communicate with the mint?

You need to have your ecash tokens before hand, which can be transferred offline.

Does one know the cost beforehand?

yes, it would display a price in sats

Of course the user would know the price of the TollGate they are communicating with. But at that point, they are offline and unable to generate another ecash token if there is a price mismatch.

I'm asking about when the user is online and preparing to go offline. How does the user know what size ecash token to make beforehand? Are all TollGates the same price? Is that price fixed?

you can generate an offline token, offline, for any amount using most cashu wallets (eg minibits)

an early version of tollgate did require old style tokens (amount is a factor of 2), pretty sure that's resolved now

operator sets the price. amount you pay is the amount you get

Did not know this. TIL, thanks.

I just tried this with the latest release of minibits. I was able to generate an ecash token offline, but still only in powers of 2. Pretty cool feature with a weird limitation. Is it possible to get trustless change?

you mean, from a tollgate operator?

It would be possible, because you'd be online by that point and could verify (claim) any change

You carry enough money (Ecash) for a few expenses: a couple of meals, a few coffees, a couple of hours of TolGate connection... The usual. :-)
