Low-power Bluetooth technology approaches RFID
For many people, RFID is often only defined as a low-cost license labeling technology for identification, and this technology is always targeted at high-volume, low-cost labeling applications such as product labeling in the retail supply chain. But in a broader sense, RFID actually includes any technology that uses wireless radio communications (including Bluetooth) to implement identification.

ABI Research has been guiding people to a broader definition of RFID, as we know of such things as contactless payments, NFC, sensor networks, and real-time location systems with network termination nodes. In addition, some wireless technologies have always been at the edge of the RFID market, but they can actually be classified as RFID. In the case of Bluetooth, this is a radio technology that supports short-range communication (typically within 10m) of the device, allowing the device to be uniquely identified. More importantly, Bluetooth is a technology that has been used in the market. Bluetooth shipments this year will be more than 500 million mobile phones. However, the primary application for Bluetooth support is to connect the mobile phone to the wireless device while ensuring that there is as little conflict or crossover as possible between the RFID and Bluetooth.
Later this year, a new short-range wireless technology specification will be introduced, and the boundaries between Bluetooth and RFID will become more blurred in the future. BLE (RFID RF Express Note: Bluetooth Low Energy, Bluetooth Low Energy) will turn all Bluetooth-enabled devices into devices that collect data from a set of ultra-low-power sensors and monitors.
The British CSR released a prototype of the low-power standard "Bluetooth Low Energy" released last year. The Bluetooth SIG estimates that Bluetooth Low Energy's mobile phones will be launched in the first quarter of 2009.
Originally developed by Nokia, BLE is used to extend the functionality of mobile phones. According to a standard set by the Bluetooth SIG specification, BLE adoption and development can be built into the next generation of Bluetooth transceivers at a very low additional cost. This marks the birth of a new generation of mobile phones.
BLE also allows BLE devices to automatically use the phone as a router for the network, and data can be automatically transferred to online applications.
BLE-related devices and mobile phones will be launched next year and will focus first on people's health and well-being applications, but in the long run, the cross-cutting trend of various applications will become more apparent (this has always been the goal of RFID suppliers). For example, in transportation and logistics applications, BLE provides a facility for drivers' mobile phones to provide voice, data communications, and GPS data. In addition, BLE will enable handsets to sense and monitor data from in-transit and online applications without the need for repetitive manual operations or other specialized RFID equipment.
Some similar application potentials will also appear in the medical and other markets, as these markets have also been the focus of RFID suppliers and application providers. Unlike RFID, BLE automatically benefits from the inclusion of millions of mobile phones.
Bluetooth, which has been covered by the pressure of RFID, is often limited to being an auxiliary function of an RFID reader. However, according to ABI Research, BLE-enabled mobile phones and BLE devices will gradually be available in the next few years, and will be expected to change the status of Bluetooth. By then, the extension of the RFID concept will be further expanded.
