Biometric fingerprint reader with proximity reader MIFARE® DESFIRE®, allowing in this case access with the combination of both technologies. This reader allows the reading of the CSN (Chip Serial Number) of the card, as well as the reading-writing of data in the memory of the card. Access to said data can be through a cryptographic key for a more secure transaction of information (Grade 4 Access). It can include a 12-key keypad that allows double factor identification with card and code. Biometric sensor with STM32L4. The reading is done through an optical sensor with a resolution of 500 dpi. The reading surface is 15x22mm. The reader can store up to 2 fingerprints per user and can be supplied (1: n operation) with a capacity for 3,000 or 5,000 users. Includes SAM module for UCA.
