However, comparing power consumption in both technologies is hardly fair, mainly because the usage can vary greatly. Therefore, what is known as "contactless", is the main application where NFC is undoubtedly a better option than BLE. The fact that no power source is required for data transfer makes them perfectly suitable for credit or debit cards, transport cards, or bicycle rental cards. On the other hand, although BLE consumes less energy than an active NFC chip, data transfer with a BLE chip without an energy source is not possible.Īnd that's why the NFC's passive mode is the most significant difference between the two technologies. One big difference with NFC technology is that communication between a device (Active) with an NFC chip and an NFC chip without any energy source (Passive) is possible. Hence, some experts in the industry anticipate NFC's demise at the hands of BLE. Despite being integrated into the Bluetooth standard, BLE was designed specifically for small data transfer and ultra-low power consumption. Although mobile devices compatible with BLE often include the previous version of Bluetooth as well, in order to avoid such incompatibility, in smaller sensors and devices this is not possible because of size and energy constraints, and are not able to work together with a non-BLE compatible mobile device.īefore BLE entered the picture, Bluetooth and NFC were addressing different and clearly defined purposes in mobile wireless communications: NFC was establishing itself as a low-power technology for short distance operations with low data traffic, while Bluetooth was being used (and is still used) extensively in the field of communications with other devices over short distances, with increased data traffic but with a higher energy consumption. Bluetooth Low Energy is not compatible with earlier versions of Bluetooth (commonly called "classic"). The basic idea was to integrate a very low power demanding wireless technology into small devices such as heart rate sensors, or other kinds of devices that needed to run on a button battery for years or months. Later on, this technology was adopted by the Bluetooth Special Interest Group (SIG) and was renamed Bluetooth Ultra Low-Power. BLE's first specifications were created at the Nokia Research Centre with the name WiBree.
