Tech Digest: More news this week

Skin-sensing smartphones

Phones already scan our eyes, face and fingerprints in exchange for access but they can still be fooled. To prevent fraudsters, German company Trinamix has developed skin-sensing tech so future scans of your face could involve checking if it’s actually made of flesh.

Twenty pound tricks

If you happen to get your hands on a new polymer £20, which went into circulation this week, Snapchat wants you to have a bit of fun with it. The messaging app has released a lens that uses augmented reality to animate the paintings of JME Turner — who features on the note — and turn the note into a fun piece of art.

TikTok lock

Chinese company TikTok has introduced a family safety mode, designed to equip parents with tighter controls on how their children use the app and ultimately manage how much time they spend on it. New controls include remotely limiting who sends them messages, turning off direct messaging and restricting inappropriate content. Warning: this may trigger temper tantrums.
