The video tutorial discusses two key wireless technologies: RFID and Bluetooth. RFID, or Radio Frequency Identification, is commonly used in industrial settings and manifests as small stickers that store data. It is also used in NFC, which allows for tap-to-pay and other smart device interactions. Bluetooth, on the other hand, connects two devices in a personal area network and comes in different classes based on signal range. The tutorial explains the pairing process and highlights the differences between Bluetooth and other wireless technologies.

What are the three classes of Bluetooth and their respective ranges?

How does the pairing process work for Bluetooth devices?

What are some common applications of Bluetooth technology in everyday devices?
