Didn't understand the card thingie on the train...
No doubt due to cultural differences. The kid hands out cards and gets money or the cards back? Is that what was going on? Someone will know!

The kid is a kind of begger. Sometimes deaf.
The kid sets cards on each person's knee, or on an adjacent seat. Usually the card is imprinted with the Sign Language Alphabet.
If you want to keep the card, you can give a donation, usually €1. I guess technically you're buying the card, but really it's not worth anything, and a lot of people give money, and don't keep the card.
You see these kids on Paris overground trains, particularly the trains out of Gare Saint-Lazare, heading west into the wealthy suburbs. Usually the kids seem about 10 to 20 years old, usually somewhere in the middle.
I think it's questionable whether most of the kids are deaf or not. I laughed out loud when Juan shouts "Hey..." and the kid turned around. I think it was a kind of inside joke after Juan gave him a $50 bill, which was extraordinarially generous. Then Juan gives the kid the miniature car, too.
