Question

Replace a Power-On Switch with NFC

We make a credit-card size Data Acquisition device which transfers data over Bluetooth to our iOS or Android App running on a phone which can be optionally attached to the phone.  The device has a PIC Microcontroller with an I2C interface and is powered by a 700 mAh Li-ion battery.

 

We want to replace or supplement the device's Power Button so the device can be powered-on with an NFC tap to the phone that is running our App.  We can add a Dynamic NFC Tag with loop antenna to do this.

Do you have a reference design showing how to do this?

Is there a demo board (perhaps with Arduino) that supports Power-on Reset using a Dynamic NFC Tag?

    Hello,

    In STMicroelectronics catalogue, there is no reference design showing this. Maybe there are other boards (Arduino ?) doing this but I am not aware of it.

    Your request is not recent, did you find a way, in the mean time, to do it that could help other people ? 

    Regards
