Mexico’s just passed a raft of invasive surveillance rules that require phone companies to get the fingerprints of everyone who buys a phone:
Also Tuesday, the Senate voted to create a registry of cell phone owners to combat kidnappings and extortions in which gangs often use untraceable mobile phones to make ransom demands.
Telecoms would be required to ask purchasers of cell phones or phone memory chips for their names, addresses and fingerprints, and to turn that information over to investigators if requested.
At present, unregulated vendors sell phones and chips for cash from streetside stands. It is unclear how such vendors would be made to comply with the new law.
