Listen to the passage. For questions 21—25, fill in the blanks with the exact words or phrases you hear.
Bluetooth technology is a method of enabling short-range communication between devices. For example, computers can connect to other computers, headsets can connect to cell phones, and headphones can connect to MP3 or MP4 players, all without wires.
In the past, wireless communication devices were too large and expensive for common use. However, there have been a lot of rapid advances in miniaturization recently. Also, more efficient forms of mass production are now possible. Both of these developments have led to the use of Bluetooth technology in a wide range of common items. Inventors are constantly investigating new ways of involving it in day-to-day life. This has resulted in the creation of a Bluetooth luggage tag.
The Bluetooth luggage tag is called The Bluebird. It is designed to notify a traveller that their bag is in close range. This makes it possible for them to know when their luggage is coming down the airport conveyor belt. It will also flash to make it easier for the person to identify his bag and will help him track multiple bags, preventing a bag being left behind by mistake.
The Bluebird also stores large amounts of information, enabling authorities to identify who the luggage belongs to simply by scanning it from Bluetooth enabled computers. Hopefully, this will mean that the age-old problem of airlines losing people’s luggage is finally over.
