Why should I when I don't need one for on line gambling etc?
But you do, if anything you need more checks to establish an account, than you would to get one of these cards.
Serious problem gamblers would probably work out how to own multiple cards anyhow, but really, those that are just starting out on the problem gambling path, may be a lot less inclined to with some proper obstacles in there way.
Getting a card will be a pretty easy process, a lot easier than signing up for a online gambling account is, and it seems the clubs (and pubs) are just crying wolf again like they did when the smoking bans came in place.
Clubs which could see what would happen, and so created more diverse income streams went well. This is just another situation like that, and given that self exclusion doesn't work, having been to counselling for problem gambling in the past, they will ratify that most clubs/pubs don't enforce it, and would just prefer to ban you from the place (which is fair enough, as I don't think it's fair to have to baby sit people who have a problem), or turn a blind eye, which is why something like this would work a lot better as the onus is on the person themselves, and given default betting limits of $100 will allow the majority of casual punters to have there fun, while the serious gamblers may increase there limit (see their is still an allowance for these types of people, just means you need to set a limit which YOU can afford).
The system is currently broken, not just from how the exclusion process works, but volume of machines in nearly every pub and club (10% of the world pokie machines are in NSW!!!), which means those with a problem have a hard time avoiding being in these situations.
The impact to the majority of people is minimal, and if anything, most clubs would probably combine a club membership with one of these types of cards to make it easier to administer, pubs will probably have greater challenges, but I don't care really about the pub situation, as they rarely contribute much to the community as a club does, and if anything, pubs should be providing a much more diverse range of activities to bring the patrons in than most do currently.
