Question 1

How do I set up a Physical Web beacon for my project?

Accepted Answer

Use protocols like Bluetooth Eddystone to broadcast URLs from beacon hardware; the project provides documentation on Eddystone and other methods, but you'll need to ensure your web content is optimized for mobile devices and internet access.

Question 2

Physical Web vs NFC: which is better for contactless interactions?

Accepted Answer

Physical Web allows automatic discovery over longer ranges without user action, but requires beacon hardware. NFC is more secure and universal for tap-based payments, but has shorter range. Choose based on range needs and security requirements.

Question 3

Is the Physical Web secure for transmitting private data?

Accepted Answer

No, because URLs are broadcast publicly and can be intercepted or spoofed. The project prioritizes openness, so it's best for non-sensitive uses like public info kiosks; implement HTTPS and validation for any critical data.

Question 4

What's the maximum range for Physical Web beacons?

Accepted Answer

Range varies by protocol: Bluetooth Eddystone beacons typically reach up to 70 meters, but obstacles reduce effectiveness. mDNS and Wi-Fi Direct offer different ranges based on network setup, as noted in the technical documentation.

Question 5

How does Physical Web handle user privacy concerns?

Accepted Answer

The protocol itself doesn't collect data, but broadcast URLs could be tracked. Users must opt-in by enabling discovery on their devices, and accessed web pages should follow privacy best practices to mitigate risks.

Question 6

Can Physical Web work without an internet connection?

Accepted Answer

Yes, but only with local protocols like mDNS or Wi-Fi Direct that broadcast URLs to local web servers, allowing offline interactions. However, most implementations assume internet access for dynamic web content.
