Make sure their phone works with EasyTap:
Compatible Devices
The phone model you have does not matter when sharing!
2. Make sure to touch your EasyTap to the very center of the back of their phone.
For Androids, the sweet spot for reading an EasyTap is in the center of the back of the device.
3. Make sure NFC is turned on in their phone settings
If their phone is on the compatible devices list and is still not reading your EasyTap, go to their phone settings and search for NFC. Make sure that "NFC" is turned on!
