A casino is a place where people come to gamble. The largest casinos are in cities like Las Vegas and Atlantic City. There are also casinos in smaller cities and towns. Some are operated by Native American tribes. Others are owned by major companies such as Caesars Entertainment Corporation. There are also some online casinos.

Most casinos have security measures to prevent cheating and stealing. These include cameras, trained staff, and strict rules about gambling. Some casinos also have separate departments for security and surveillance. The security department usually patrols the premises and responds to calls for assistance or reports of suspicious activity. The surveillance department operates the casino’s closed circuit television system, known as the eye in the sky.

Casinos are often a target for criminals because they handle large amounts of money. Both patrons and employees may be tempted to steal or cheat. Security measures are therefore very important. Many casinos have security cameras throughout the building and trained personnel to deal with any incidents that occur.

The best casinos offer a variety of secure payment methods. These include popular cards like VISA and e-wallets such as PayPal. Some even accept cryptocurrencies like Bitcoin. Look for a casino that offers these options and makes them clear on their website. A good casino will also have a detailed FAQ section that answers common questions quickly. Also, check the casino’s customer service response time. You want a site that can answer your questions within a day or two.
