Report: Galaxy S8 Fingerprint Reader on Backside Because Time Ran Out... �_(%u30C4)_/� | Droid Life. It is a no brainer for someone who is committing a crime to ignore the rush to fingerprint readers on smartphones, since a user can be forced to provide a fingerprint to gain access to the contents of a smartphone as a physical attribute. However, forcing someone to give up something in their head, like a pin code or password, is a different animal. No person can be required to provide testimonial evidence against themselves. The tension between law enforcement and a person of interest in a criminal investigation is palpable, and, while sometimes distasteful, the freedom not to testify against oneself is a bulwark of a free society. What has this to do with lawyers? Well, lawyers represent criminals and other persons. Lawyers are required by their oath and by law to keep the confidences of their clients secret unless the client intends to violate the law. In any event, lawyers need to be very careful with modern smartphones if they harbor confidential client information. The safest course? Use a pin code or a password to gain access to your smartphone. And, encrypt the contents. Be safe out there.
