It is an upgraded version of the MIFARE DESFire EV1 and is commonly used in public transportation, access control, e-payment, and identity management systems. Key Features of MIFARE DESFire EV2: High Security Uses AES-128, 2K3DES, and 3K3DES encryption Secure messaging and authentication Supports secure key management Multi-Application Support Can hold up to 32 applications Each application can have up to 32 files Enables multi-service use (e.g., transport, access control, and payments on one card) Improved Memory and Performance Available in 2 KB, 4 KB, and 8 KB memory options Faster transaction speeds compared to EV1 Secure Proximity Communication Based on ISO/IEC 14443A (13.56 MHz) Supports NFC Type 4 for mobile compatibility Transaction MAC (TMAC) Support Provides additional security for transactions Hel...

Palm print scanners are biometric devices that capture and analyze the unique patterns and features on the palm of a person's hand for identification and authentication. How they work: Image Capture: The user places their palm on the scanner's surface Image Processing: The scanner captures an image of the palm, focusing on unique features like lines, wrinkles, and creases. 3 Feature Extraction: The system extracts key features from the captured image Comparison: The extracted features are compared to a previously stored template of the individual's palm print. 5 Authentication: If the palm print matches the stored template, the system authenticates the individual's identity. Key Features of Palm Print Scanners: High Accuracy: Palm prints offer a large surface area with many unique features, leading to high accuracy in identification Difficult to Spoof: Palm prints are more difficult to forge compared to fingerprints. Versatility: Can be used for various...
