Casinos are running because of money. Every casino has as goal to make the most money it can. Taking this in consideration, we can say that casinos like innovations that bring more money.
Casinos want to use game machines that will automatically download the newest software so they will not need to be changed. Casinos want to save a lot with this. Also, casinos want to use special cards instead of money. This would make casinos need less personal, because there would be less need for persons to care about the money in the casino. If casinos reduce the use of money, they reduce the risk of stealing and cheating.
Casinos also want to use new cameras and face recognition. In this way it would be easy to catch cheaters, high rollers and other risks for the casino. People probably won’t like these cameras, because nobody likes when the whole world sees how much is won and such things. Technology brings a lot of new things but these new things are not necessarily good for the players. Slot machines bring a lot of money so casinos try to use as many as possible of them. Table games start to be pushed in the background and probably will be forgotten after a time.
If real casinos fail to satisfy the needs of players, probably online casinos will take their places. Online casinos are very easy to make and they do not need working staff. We can see new technology like virtual realities that look almost like the real world. We can see also things like equipments that can understand human movement and can control a virtual human. If we combine these things, so we will be able to walk in online casinos that will look like real ones.
Probably the casino of the future will be customizable. We will be able to put the tables and slot machines anywhere inside and also play on them. Even now online casinos are pretty fine but they still have moneymaking as goal. Until this remains so, we will not see great improvements in 3d graphics, just in games.
