I understand how RFID works. However, that "communication between the gun and the device" will require a power source in the gun and a mechanical interface to block or unblock the trigger mechanism in order to function as an ID screening device.bmwrdr wrote:RFID sensors work without battery, it uses the same concept as an antenna. Those chips are used in access control systems for example. You get that chip close to a device with a power source and that device can read the code on the RFID chip.Excaliber wrote:I understand the technology, but how do you get the charge dependent battery and the extra points of failure presented by the electronics / mechanical interface out of the mix?bmwrdr wrote:I am not trying to support evil and stupidity but RFID technology would be the key technology.
Here's another thought:
How often do you clean your gun when you haven' fired it?
Extend that thought: How often do you think you'd charge or test and replace the RFID circuit's battery?
How smart does that "smart" technology look when you pull the trigger in the 1.5 seconds you have to resolve a deadly threat and nothing happens?
The extension of the RFID chip embedded in your gun could be your cell phone (smart phone) with an app to communicate between the gun and the device.
I am not a supporter of such a device but as you may very well know, technology does not stop,
An RFID chip alone is just decoration and/or a tracking device that can be read by a nearby antenna.
