This relates to the engineering world because people are always getting past locks, but this lock is much harder to get past with hacking or simple lock-picking. Since locks are so incredibly common, from unlocking your house to unlocking your phone or laptop. This lock can is harder to hack than a fingerprint or other locks. The only problem is that the error rate could cause a serious problem. So I believe this technology could be very useful in the future, when the error rate will be improved. This is also really beneficial as it gives off no radiation. This technology could be used all around the world for hundreds of different purposes.
