Transaction. An exchange of data resulting in a transfer of goods,
services, value, and/or information between two parties. Example: A
customer provides a magnetic-stripe card to a merchant. The account
number on the card is read via a VeriFone terminal. The terminal
exchanges data with a host computer, which provides verification of
the account's validity. The customer is then provided with goods,
services, or information, and the merchant has value added to his
account in exchange.
Truncate. To shorten a number, usually by one or more digits, when
the number is placed in a memory location that is too small to store all
of the digits. For example, 1.2345 is truncated to 1.23 when stored in
a location that can hold only four characters.
TXO. VeriFone's 'Transaction eXpress Option'. An operating system
that utilizes the standard C programming language. Also, the line of
VeriFone products based on the TXO operating system.
Variable. A string of characters that is used to denote some value
stored within the computer and which may be changed during
execution. A variable may be internal to a program, in which case it is
held in memory, or external if the program must perform an input
operation in order to read its value. See 'Parameter'.
