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?
