Office worker Ana Martínez lined up at 7 a.m. on a recent Sunday to renew her voter credential, a document required at a polling station to vote.

But voting was not the main reason she was getting it. The free photo ID issued by the Federal Electoral Institute had become the accepted way to prove one's identity — and is a one-card way to open a bank account, board an airplane and buy beer.

Voting was almost an afterthought. "They ask for it everywhere," Martinez said. "It's very difficult to live without it."
