OVERVIEW
|
||
|
|
|
||
|
|
- Lockitall is under new management.
|
||
|
|
- All vulnerabilities in our old locks are now resolved.
|
||
|
|
|
||
|
|
DETAILS
|
||
|
|
|
||
|
|
The LockIT 2 A.03 is the second of a new series of locks. It is
|
||
|
|
controlled by a MSP430 microcontroller. The MSP430 is a very low-
|
||
|
|
power device, chosen because we found several crates of old stock.
|
||
|
|
|
||
|
|
This lock only accepts biometric and NFC inputs, and does not have
|
||
|
|
a traditional password prompt.
|
||
|
|
|
||
|
|
To support rapid development cycles this lock accepts a program
|
||
|
|
from the old password input prompt. Only programs signed by us are
|
||
|
|
allowed.
