Ireland can't really do a national id scheme without mutual agreement with the UK due to the common travel area & mutual residence rights (including voting at parliamentary level upon taking residence) that are dealt with in an ad-hoc manner for many reasons. due to this, Ireland has default opt-out on justice & home affairs issues.

however, as an EU citizen, I can see immediate advantages to a cautiously administered digital id. as it is, many states within the EU demand a national tax id on registration for services as simple as bike rental, such a digital id would presumably supersede such nonsense and help further the single market everyone is working towards.
