It could be implemented today, and it needs to be implemented.
There could be no fraud at all. The voter would need to be identified 4 ways, driver license, voter registration card, fingerprint and retina scan. Once the credentials are established, the fingerprint or the retina scan would be sufficient. There is no way to “fake” the person’s identity. And then the voting could be done online, on the internet. Since we have the technology to do all the financing on-line, to create a voting system would be very simple. Pretty much everyone has a smart phone.
And, of course we should get rid of this electoral system. It was a good idea back then, but today it is obsolete.
