Casinos work because of the money. Each casino aims to make as much money as possible. Taking into account, we can say that casinos like innovations that bring more money.
Casinos want to use game machines that automatically download the most recent software so you do not need to be changed. Casinos want to save a lot with that. In addition, casinos want to use special maps instead of money. It would make the casinos need less staff because there would be less need than people care about 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 cheats, high rollers and other risks for the casino. People would probably not like to love these cameras, because nobody likes when the world sees the amount of won and such things. Technology brings a lot of new things, but these new things are not necessarily good for players. Slot machines bring a lot of money so that casinos are trying to use as much as possible. Table games start to be pushed into the background and will probably be forgotten after an hour.
If real casinos do not meet the needs of players, online casinos will probably become their places. Online casinos are very easy to do and they do not need work staff. We can see new technologies like virtual realities that look like the real world almost like. We can also see things like equipment that can understand the human movement and can control a virtual human. If we combine these things, we will be able to walk in online casinos that will look like true.
The casino of the future will probably be customizable. We will be able to put the tables and machines on anywhere inside and play on them. Even now, online casinos are pretty brought, but they always have migration as a goal. Until this remains, we will not see great improvements in 3D graphics just in the games.
