If someone has an idea they want to sell, let the market decide if it's viable. All these ideas come, and go. The free-market is working as intended, hence none of this technology has taken root.
The government should not make the technology mandatory. If there is enough demand for such technology, the manufacturers will adjust.
For any of my firearms that require me to keep them secured and readily accessible, such as my bedside gun (I have children that touch and explore everything), I don't trust electronic locks. I'm generally OK with electronic locks on storage devices that don't require immediate, relatively bomb-proof, access. I don't foresee "smart-gun" technology being something I will embrace, especially when it totally disables the firearm, or requires fingerprint, RFID/NFC, communication.
