Moussa Sinon asked 1 year ago We are developing a service using Near Field Communication (NFC) technology. The service includes a mini terminal with an NFC chip. The function of the terminal is to continuously broadcast a dynamic code from its chip. Users equipped with a mobile device having our application can detect and read the code with the chip of their device. As soon as an equipped mobile device reads the code, the terminal immediately generates a new code and so on. Our current challenge: We want the terminal's signal, the code, to be read within a radius of 150 to 200 centimeters (59 to 79 inches) by a phone's NFC tag. Do you have a solution for us? Would it be possible to extend the range of the NFC signal, or to replace NFC with another RFID tag that would do the same job but with a wider radius than NFC?

Moussa,
If your application works with mobile devices, and if you require a range of 150 centimeters or more, you might want to look at Bluetooth Low Energy (BLE) options. I spoke with HID Global, which offers NFC and other RFID technologies, and the company indicated that your application would be better suited for BLE; however, you would need an app on your phone. NFC is more often dedicated to very close-range use cases, such as access control, authentication and touch-free payments.
