We are building a kiosk and we need the ability to share an image (or a url to an image) across different social networks.
I dislike the idea of asking for login credentials for each network. The process takes way too long and I know I'd feel very uneasy typing my credentials into a public machine right out in the open.
Would my best bet here be getting it to the user and letting them share it from the comfort of their own device? What would be the best method to do this? QR Code? SMS? Email?
Here's my opinions on the different options:
My gut is telling me email is the safest bet. I feel like this would be most easily understood by users of the most age groups.
A QR code would be perfect since it requires no input from the user and it's instant but I'm not sure it's understood by enough people.
An SMS would be almost as good as an email but I feel only slightly more comfortable giving away my email address. Not sure if people feel the same way about this as me.
Anyone using these methods have any data on what's the most successful? Any method I completely skipped?
