• 505 accidental firearm deaths in 2013
• Many of these are preventable by better storage solutions
• Many gun owners are in search of a more accessible storage option.
• This is NOT a perfect solution to firearm storage.
• Other methods are still needed for complete security.

System

Methods

• The Biometric Trigger Lock is a system that clamps around a firearm’s trigger guard as shown:
  
• An aluminum housing was used to hold all the components and cover the trigger guard.
• TTL serial fingerprint scanner stores prints and checks them.
• 12V solenoid lock to unlock the system

Conclusion

A fingerprint trigger lock is absolutely a viable option for firearm storage.
• More research would need to be done in order to find the best method to secure the system to the firearm’s trigger guard.
• System responds and unlocks in about 1 second, making it a very accessible system.
• With more refinement, the system could be a marketable option
• Relatively high-current batteries are needed to actuate a solenoid lock properly.
• The design can be refined and marketed to firearms or security businesses.
