I understand your need to keep it vague, but if the data owner loses

Nothing should be dependent upon a particular person, device or
storage medium. The village might be serviced by different people with
different laptops each time. There are lots of people fulfilling this
function, each with his/her area to service. The data from all these
people only comes together at the central office. The laptop should
only really be storing the data it picks up on its travels, not
carrying a repository of millions of account holders.
This is becoming a little like a game of charades. But is it only one motorcycle
borne reader/writer who accesses the card?
As ERG and the NSW government have discovered the card and reader are not the
hard bit, but there might be some relevant information here.

Having
endusers with no proof of a transaction or ability to read their own
data I would have thought has the potential for a lot of social
issues, and potential non acceptance of the technology.
Interesting point. To be honest I didn't think of that.
You may have already considered this though - it all comes down to the
data value. Presumably if the cost of storage has to be <$1 then the
value of the data might only be $100 or less (by my reckoning)
In dollar terms, yes. But that's a hell of a lot of money for these people.
