I have found that the administrative costs of PKI are
intolerable. End users do not really understand crypto, and so
will fuck up. Only engineers can really control a PKI
certificate, and for the most part they just do not.

In principle the thingness of a smartcard should reduce
administrative costs to a low level -- they should supposedly
act like a purse, a key, a credit card, hence near zero user
training required.  The simulated thingness created by
cryptographic cleverness should be manifested to the user as
physical thingness of the card.

Suppose, for example, we had working Chaumian digicash.  Now
imagine how much trouble the average end user is going to get
into with backups, and with moving digicash from one computer
to another.  If all unused Chaumian tokens live in a smartcard,
one might expect the problem to vanish.  The purselike
character of the card sustains the coin like character of
Chaumian tokens.

Of course if one has to supply the correct driver for the smart
card, then the administration problem reappears.

USB smartcard interfaces could solve this problem.   Just plug
them in, and bingo, it should just go.  Ummh, wait a moment, go
where, do what?  What happens when one plugs in a USB smartcard
interface?

Still, making crypto embodied in smart cards intelligible to
the masses would seem to be a soluble problem, even if not yet
solved, whereas software only crypto is always going to boggle
the masses.

At most, it'll contain a name+password for HTTP basic-auth (and to identify
users to the site so they can be connected with the info they supplied at
purchase time).  You've spent too long in the crypto world.

Having poked around in the FAQ (I can't believe I'm wasting my time on this),
it could be one of three things:

1. Dumb memory card.

2. As (1) but with basic PIN-protected memory region (unlikely, since the user
   isn't asked to enter a PIN and unique PINs means they can't hardcode it
   into the access software).

3. Eurochip-type challenge-response card.  In other words, a phone card.  Also
   not too likely, since you can't do this via basic-auth.

The FAQ handwaves the details, so it could be either 1 or 3.  Can someone who
has one of these things try reading the ATR off it?

(You can also see, from the large number of FAQ entries covering potential
 problems and all the warnings about things to look out for when you use the
 card/reader, how not-ready-for-prime-time smart cards still are).

I wrote:

The FAQ handwaves the details, so it could be either 1 or 3.  Can someone who

He Who has No Shame [0] reports that it's a GemClub memory card, which is
reasonably similar to the old SLE4428-style cards: 256 bytes of memory, some
of it PIN-protected.  Available commands are read, write, and verify PIN.
Given the info in the FAQ, it would appear that the PIN is fixed/hardcoded
into the driver, since there's no indication that users are asked for it, and
it mentions that if someone else finds your card, they get access (or they may
just use the non-protected storage in the card).  I'm guessing this was a
marketing decision, expecting x-teen-year-old kids (whatever the target market
for these things is) to remember and enter PINs, not to mention the UI issues
involved in obtaining the things, would make it unworkable, while reading off
a URL and password and poking it into a browser is something which is a lot
safer to deploy.

Access control is by an XML version of basic-auth.

In other words, it's (effectively) a dumb memory card with (effectively) HTTP
basic-auth.  It does however use the T=0 serial protocol and not I2C, which is
a bit trickier to read with wires poked in the parallel port :-).

Smartflash is supposed to be plug and play, no installation, no 
configuration.  You just plug it into a usb port, poke your 
card into the reader and a browser window pops up, and takes 
you to the web page for that smartcard.  If any software is 
needed, then it is in the form of activeX component, which 
means that the only installation interface is Do you trust 
this software from so-and-so?

When Chaumian money comes into wide use, I think that for most
end users we will have to stash all unused tokens inside 
smartcards.  However, because of the critical mass problem, 
initial deployment for small payments cannot rely on such 
means, though initial deployment for large payments could.

Unfortunately, deployment of uncrippled chaumian cash for large 
payments is likely to be illegal in most jurisdictions.

could be user-friendly and not implement them.
They didn't just shoot themselves in the foot,
they went out looking for more feet to shoot at.
A Starbucks two blocks from my office accepted Mondex
as payments for coffee, which would seem to be ideal,
especially since there was a Wells Fargo Bank branch
two blocks from them with a big Mondex sign on the door.
But you couldn't just walk into the bank, slap down some
dead presidents, get your card, and go buy coffee.
You walked up to the unmanned Mondex desk, which had paper forms
and a phone that called some office that had somebody who
would tell you how to fill out the forms and snail-mail
them in to people along with your bank account information
who would then snail-mail you your card,
though once you'd done so I gather you could refill it easily.
I don't remember if you had to have a Wells Fargo bank account to do it,
or could get by with a Visa card instead - I think the former.

A previous company I worked for made a secure smart-card reader
chip/system that used smart cards to carry a user's private key and
cert.  The initial application was the SET electronic payment protocol.
(all together now: yuck!)  SET didn't take off, and not many of these
were sold.

Amex hyped up their 'blue' card  was giving out free readers for
a while... until they discovered that the drivers were fatally broken
(ha ha, it was done by a competitor of the company above, their
product was shite).  That, plus the fact that Amex couldn't get
more than a few merchants to go along with it, doomed the project.
They stopped giving out free smartcard readers pretty quickly.

The company I work for now uses smart-cards in a K-of-N split key
scheme to authenticate administrators of secure proxy servers.  These are
actually selling to real live customers and work just fine.

Niche markets like these are the only place where smart card use will
