They wanted to write “fingertip,” but instead, they wrote a curious word: “finger PULP”
The touch screens of mobile devices only respond if we touch them with some skin. We know this because when it’s freezing, and we wear gloves, we can’t press the elements on our screen. They don’t work either if you try to touch them with your nails. If you’re a fan of acrylic nails, you probably already knew that.
The visual content of this sign is outstanding; we understand that we must touch the button with our finger, undoubtedly because it must read a fingerprint. What confuses us is the written part. What is the “pulp” of the finger? Is there a juicy part on the fingers? They probably mean fingertip, but their chosen word is really questionable.
