difference between Bluetooth and NFC 

**Bluetooth:**

1. **Range:** Typically up to 100 meters.

2. **Data Rate:** Supports higher data transfer rates, up to 3 Mbps.

3. **Power Consumption:** Generally higher compared to NFC.

4. **Applications:** Used for connecting devices like headphones, keyboards, and smartwatches.

5. **Pairing:** Requires a pairing process to establish a connection.

**NFC (Near Field Communication):**

1. **Range:** Typically up to 10 cm.

2. **Data Rate:** Supports lower data transfer rates, up to 424 kbps.

3. **Power Consumption:** Generally lower compared to Bluetooth.

4. **Applications:** Used for contactless payments, access control, and data exchange between devices in close proximity.

5. **Pairing:** No pairing process needed; devices can communicate simply by being near each other.
