ELI5: Someone in Mexico wrote down my drivers license number after I used a debit machine in his store. Why did he do this and what potential damage can he do with it?

I don't think this is an attempt at fraud, but rather an attempt to prevent it. He doesn't know you, but if he has your DLN and the card you used comes up stolen, he can sick law enforcement on you because you gave him definitive ID. He's probably been scammed one too many times.
