Make sure their phone works with Social Master: Compatible Devices
2. Make sure to touch your Social Master to the very center of the back of their phone.
For Androids, the sweet spot for reading a Social Master is in the center of the back of the device.
3. Turn on NFC capabilities in their phone settings If their phone is on the compatible devices list and is still not reading your Social Master, go to their phone settings and search for NFC. Make sure that "NFC" is turned on!
