Similar systems using pre-paid cards for public phones are common in
most European countries.  You buy a card, normally from a post office
or newsagent, which is worth a certain number of units.  The units are
deducted from the card as you speak.
 
There seem to be three systems in use:

* a 'smart card' with an in-built chip, used in France, Germany
and Ireland

* a holographic system used in Austria and by British Telecom in
the U.K.

* a magnetic card system used in Italy.  I think the Mercury phones
in the U.K. also use a magnetic system.
 
The use of card phones is becoming increasingly common: in France
coin-operated payphones (without a queue) can be hard to find.  I
think the reason for their absence in the U.S. is their dependence on
meter pulsing for billing.

Just as a BTW, I had no problems making international calls from
payphones in Czechoslovakia this autumn.  Line quality to Ireland and
West Germany was excellent.

Remember that the UK (and possibly the continent) has only recently
moved over to tone dialling.  I think the introduction of cardphones
was because credit card calling is a non-starter without tone.

Cheers,

Neither did I in late August from Praha.  International calls to the
USA could be made either from the hotel switchboard direct dial or
from a payphone and it was relatively inexpensive (about Kcs100 for
three minutes, about $4.00).  However international service was
difficult to obtain or unavailable in the provinces, where payphones
themselves were scarce!
