A serverless social cards sharing web app
It's like "contact address" with social media usernames (Snapchat, Facebook, Twitter, Instagram, Phone, etc.)
It can be used to share contacts in less of a minute with anyone using a QR Code.
It is Server 'less (emphasised): It does not send data from users browsers anywhere; Still, users can share their cards.
It just uses URLs and QR Code.
I implemented each time a new version in a simplistic fashion so that next versions do not hurt QR-Codes made with earlier versions x) Although I note that the last version (3) is the one 100% server-less (no URL loggings assured by design).
A link is like this:
Check this card to see the corresponding QR-Code and social card online. Know that the card is deciphered from the Link only, no session, no db, no information rests in server.
