To combat this, safe manufacturers were constantly coming up with ways to combat the latest safe cracking techniques. As a result, the safes of today are virtually impenetrable. There will always be a handful of safe crackers out there that can get in, of course, but in general modern safes are just too much for most criminals to deal with. They cannot fathom the materials and electronic security features that go into the modern safe. There are safes these days protected by fingerprint identification, voice identification, and even retinal identification. It is truly amazing to see how far we’ve come in just two centuries of safe manufacturing.
