A contactless smart card is a physical security device that uses radio frequency identification (RFID) technology to identify and authenticate an individual. This type of card is used in a variety of applications, such as access control systems and digital payment systems. It is also used in physical access control systems, where the card is used to unlock doors or grant access to restricted areas. Contactless smart cards are also used in building access systems, where the card is used to grant access to certain areas of the building.

A building or a portion of a building whose primary function is to house a computer room and its related support areas. A Data Center is a secure, temperature-controlled environment that houses computer systems, equipment, and associated components. It is typically used to store, process, and distribute large amounts of data and information. Data Centers typically include server racks, storage arrays, network switches, firewalls, and other components necessary for the operation of computer systems.

There are five common approaches to removing unwanted heat from an IT environment:

• Air conditioning: using mechanical cooling to remove heat from the air.
• Air economization: using outside air to cool the IT environment when the temperature is cooler than the desired temperature inside the data center.
• Liquid cooling: using a liquid coolant to absorb and remove heat from IT equipment.
• Evaporative cooling: using water evaporation to cool the air.
• Immersion cooling: submerging IT equipment in a liquid coolant to remove heat.
