This protocol is intended to provide a short duration transaction
service for dial-in and network connected POS, Visa, and other short
duration transaction applications to transfer data between the
access routers and transaction based servers over an IP network.
As the world has moved towards IP based backbone networks, a need
has arisen for the ability to conduct short duration transactions
over these networks. Such short duration transactions are integral
to Visa, EFTPOS, security monitoring, alarm monitoring, meter
reading, toll monitoring, location information (i.e. GPS), EDI, and
a wide variety of other applications in similar environments.
The Quick Transaction Protocol (QTP) specifies a protocol to be used
over IP networks for short duration transactions. It is based on
the concept of peer to peer delivery of transaction data in a
fashion analogous to the Connectionless Network Protocol (CLNP). As
such it extends the use of CLNP over IP networks.
While QTP may be used as a transport protocol over either UDP or
TCP, UDP is recommended as it minimizes the variable delay of the
network. This allows implementation of transaction protocols such
as VISA II to be done in the transaction server as well as allowing
for transactions where delivery of data must be fair to all
customers such as in stock feeds.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
