Yes, digital business card tapje.la is compatible with all modern smartphones. There are 2 primary ways to share:
Tapping – this feature works explicitly with NFC-enabled devices.
If your device is not within the list, it might also be that we missed it out from the list. A quick Google search will reveal whether your device has NFC included.
Scanning – Should your device not come with NFC or you prefer sharing via QR codes, every card comes with its own unique profile QR code which opens the same user profile as tapping would.
