Tim Deguette, the founder of Solly, a digital donation solution for the homeless poses for a photograph with a Solly card in Lille, northern France on November 21, 2025. A new digital donations solution for the homeless was launched in Lille, before being deployed elsewhere in France. This community project, conceived by a 22-year-old from Lille, aims to address the problem of cash shortages, which often prevents passers-by from donating to the homeless. These cards are used for payments, but only work for purchasing essential goods or overnight stays. (Photo by Sameer Al-DOUMY / AFP via Getty Images)
