Deputy Ó Murchú is are asking about the verifier app on a phone that can scan a QR code and then come up with the information. The information that shows on screen is the same as the printed information on the sheet of paper. There are no extra data there. They are all encoded in the QR code. The Department of Justice developed this app for its immigration staff, and I believe it is the same app that is used by the carriers where they choose to use it. It is an Android app. It is not available in an app store and it must be directly loaded on to a phone, or side loaded for use. In that sense it would have to be put into an app store if it was to be used generally for everybody in hospitality and the hospitality sector, which makes it a bit different. It works on the Android operating system and not on the iPhone system, so you would probably want something that worked on both. Many other countries have produced their own scanning apps with different levels of success. Not all of them are 100% compliant with the rules. I noticed, for example, that the Luxembourg Government app, covidcheck.lu, has an app that can scan a person's code. If he or she wants to put the app on a phone and scan a QR code, they can. That is an option also.
