I thought this was a spoof / 'The Onion' style story, then I saw this.<p>> The Pay-with-a-Group-Selfie (PGS) project, funded by the Melinda & Bill Gates Foundation, has developed a micro-payment system that supports everyday small transactions...
We (Ticketleap) did something similar in ticketing. <a href="https://www.ticketleap.com/info/selfie-ticket" rel="nofollow">https://www.ticketleap.com/info/selfie-ticket</a>
From the paper:<p>> [Pay with a Group Selfie (PGS)] is a mobile payment technique that leverages on face-to-face exchanges where pictures taken with mobile phones are used to embed all information (the parties’ identities, the exchanged goods/services, and the price) of a business transaction. The system relies on Visual Cryptography (VC) to generate two untamperable shares of the selfie showing the transaction. The buyer and the seller hold a share each, and the transaction can be checked simply by stacking the shares.
I have a hard time considering something "human-centred" when the very concept seems completely inaccessible to people with visual or motor impairments.
Possibly one of the worse funding decisions by bill gates' foundation.<p>Even in poor, rural communities in India, more feasible payment methods backed by the government (BHIM) seems more practical than this paper
"The gesture - taking a selfie - has become part of the lifestyle of mobile phone users worldwide, including non-technology-savvy ones." Since when has taking a picture with a mobile phone been relegated only to "technology-savvy" people?
