Networking is a two-way street. Of course, you'll want to easily scan any business cards you receive, however, we at Bluewhale believe that physical business cards should be a thing of the past. Exchanging contact information is key, and we're not talking about sending an email or text message. We're talking about wirelessly and effortlessly exchanging that information. We're dedicated to make Wobb as good as possible, and wireless technology is a key part of that plan. In this post I'll do my best to give a small overview of the technology we're using.

Near Field Communication.

Near Field Communication (NFC) enables devices to exchange information when brought within 4cm of each other. These days, most modern phones are NFC-enabled. In the case of Wobb, two phones can be brought close together and exchange contact cards without even unlocking the phones*. The two devices will then exchange the primary cards from each user. That's it!

It's also possible to use any NFC tag to share contact information, as we're using deep links in the NFC payload. These NFC tags are cheap, small inlays that can be inserted and applied to anything you like. For example, If you still want your physical business cards, you can take it to the next level by applying NFC tags to the cards. This way, Wobb users don't have to receive the card, as they'll get it in the app. For this purpose, we're including a NFC writer feature in the release of Wobb.

Bluetooth Low Energy.

Bluetooth Low Energy (BLE) enables devices to act as beacons. These beacons use BLE to transmit a unique signal to nearby devices. This technology is particularly useful for one-to-many exchange situations, where one user can share a card with all nearby devices. It's also a more passive approach than NFC, where the users can manually select which nearby users to add. Wobb will be compatible with dedicated, physical beacons further down the road.

Quick Response Codes.

Commonly known as QR-codes, these machine-readable labels are widely used today. Every phone with a camera can read QR codes, and the encoding modes are standardised. Even phones without Wobb can scan QR-codes, and still be able to receive the card being shared. Even though QR codes are widely used, this is the technology that can require the most time and interaction compared to NFC and BLE. However, not all phones are NFC-enabled or supports BLE, therefore QR codes can be viable in many cases.

All of these technologies will be ready for you to test out when the Pilot Program rolls out during the next months!
