CAMA-SM12 fingerprint acquisition and monolithic processor fingerprint combo design of fingerprint identification secondary development of fingerprint acquisition head has the advantages of small volume, low power consumption, simple interface, high reliability, fingerprint template small (498 bytes), large capacity fingerprint identification (3000 pieces of fingerprint recognition response time less than 1 second) etc., can be very convenient to embed user system composition satisfy customer demand for fingerprint identification products.
In particular, self learning function, fingerprint identification process, the most recent extraction of the fingerprint identification value after the success of the feature value is fused to the fingerprint database, the use of the user in the process of using the better.
CAMA-SM12 communication interface module for the UART, the module as from the device, by the master device sends commands to the of the control module with adjustable level of security function, fingerprint feature data read / write function and 1: n recognition and 1:1 verification function.
The development of CAMA-SM12 fingerprint acquisition head machine is through the UART send and receive instructions
To achieve the registration and comparison of the fingerprint data the minimum storage conditions: the fingerprint template is 498 bytes
The total reflection optical fingerprint sensor
The 1:N identification and 1:1 verification function
The fingerprint data read / write functions
It may be appropriate to adjust the security level
The fingerprint and extract characteristic value upload, download function of fingerprint characteristic value and the current fingerprint acquisition
The function is particularly suitable for verifying whether a fingerprint is stored in a contact IC card or a contactless IC card to verify whether or not the card is in the form of a card.
