Wireless presentation system and pairing method applied thereto

A wireless presentation system comprising:

• a first wireless input element including a first identification code storage unit;
• a second wireless input element including a second identification code storage unit;
• and
• a wireless receiving and processing host communicated with the first wireless input element and the second wireless input element, wherein the wireless receiving and processing host generates a first identification code, and if the first wireless input element is present, issues the first identification code to the first identification code storage unit of the first wireless input element for storage, so that the pairing relation between the first wireless input element and the wireless receiving and processing host is established by the first identification code to control presentation;
• and the wireless receiving and processing host automatically generates a second identification code after the first identification code is issued, and if the second wireless input element is present, issues the second identification code to the second identification code storage unit of the second wireless input element for storage, so that the pairing relation between the second wireless input element and the wireless receiving and processing host is established by the second identification code to control presentation;
• wherein each of the first and second identification codes issued by a wireless receiver of the wireless receiving and processing host comprises a component identity code denoting an identity of the wireless receiver;
• and a serial number generated if the first or second wireless input element is present.
