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.

Methods of manufacturing a valve bag are disclosed. First and second webs of valve material, such as heat sealable plastic film, are combined to create a combined web of valve material, and a sealing process is applied thereto to define valve portions. The combined web of valve material includes a plurality of valve strip portions, each including a valve portion. Then first and second bag sections, which may be on a first and second side respectively of a web of folded bag material, or on a first web and second web of bag material respectively, are dispensed with the combined web of valve material positioned in between, and brought together to form a combined web of valve bag material. A sealing process is applied to the combined web of valve bag material, forming a valve bag section. The bag section is then separated from the remainder of the combined web of valve bag material to form an individual valve bag.
