A means for confirming transactions through the use of embedded and encrypted questions displayed as patterns on a graphical display

摘要

Means are disclosed for facilitating a transaction whereby a series of one or more questions are encoded and preferably encrypted, for example as a graphical pattern such as a 2-dimensional barcode, and wherein the questions are utilised for the purposes of confirming details pertinent to a transaction, such as a purchase from a shop or over the internet or a transfer of monies between personal bank accounts or a granting of permission of access or use or transfer of responsibility and so on, by displaying said questions on a personal portable device such as a mobile telephone for example. Answers given to said questions may then be used to form the basis for the transaction by defining for example articles or services being purchased or amounts of monies being transferred as well as details such as the accounts involved in the transaction and the desired timing details and so on.
