Abstract
This document discusses, among other things, a system and method for detecting an initiation of a transaction and generating a string of characters based on the detection. A first portion of the string of characters may be presented in such a way as to be distinguished from a second portion of the string of characters. In various example embodiments, the transaction is validated based on an identification of the first portion of the string of characters.
