Why each option
Bluetooth is a short-range wireless technology specifically designed to replace cables between portable and mobile devices while providing built-in security mechanisms.
Bluetooth was created explicitly as a cable replacement standard for short-range personal area networking (PAN), operating over the 2.4 GHz ISM band with built-in pairing, authentication, and encryption features, making it ideal for connecting phones, headsets, keyboards, and other peripherals wirelessly at close range.
Radio-Frequency Identification (RFID) is a tracking and identification technology used to store and retrieve data from tags; it is not designed as a cable replacement for interactive device communication.
WLAN (Wi-Fi) is a longer-range networking technology that connects devices to a local area network infrastructure, not a personal cable replacement standard for direct device-to-device use.
InfraRed (IR) requires strict line-of-sight alignment between devices and has been largely replaced by Bluetooth precisely because it does not offer the flexibility or security needed for modern cable replacement.
