Yes, some RFID tags can be reused and assigned to another item and some RFID tags can be reprogrammed (EPC and User memory) to store new information about new items.

What factors should I consider when choosing a wireless technology for my application?

When selecting a wireless technology, it's essential to consider factors such as data rate, coverage area, power consumption, and application requirements. Each technology has its strengths and weaknesses, so understanding your specific needs will help you make the right choice.

When would you choose UWB over Bluetooth / BLE or Wi-Fi?

UWB offers very high data transfer rates (≈ 1 Gbps) over its range (~10 meters), which can be useful when high-speed short-range data exchange is needed. Because of its characteristics, UWB is particularly suited for applications like indoor navigation, asset tracking, and proximity-based services. Also, compared to other longer-range or lower-data-rate technologies, UWB can play a unique role when both speed and short-range precision are required.

How does Ultra-Wideband (UWB) compare to NFC?

UWB is very distinct technology than NFC, here is how:

UWB operates over a wide frequency spectrum (e.g. 3.1 GHz to 10.6 GHz) and can deliver very high data rates, much higher than NFC.
NFC operates at a fixed frequency (13.56 MHz), at low data rates.
UWB supports accurate ranging and positioning capabilities (centimeter-level accuracy), which NFC cannot; NFC is mainly for simple short-range communication.

What is the difference between Bluetooth and NFC?

The difference between BLE and NFC is as follows:

Bluetooth (or Bluetooth Low Energy, BLE) works over a relatively longer range (tens to hundreds of meters) and supports higher data transfer rates.
NFC operates only over very short distances (a few centimetres); ideal for very close-range data exchange or tap-to-connect scenarios.
NFC setup is simpler, often requires little or no pairing, and consumes very low power, making it suitable for quick, low-data tasks (e.g. payments, access control).
