exif: {"Image DocumentName": "A Smart card transaction", "Image ImageDescription": "Step 5: Identifying security requirements. The card is able to define the security requirements for the selected application. The card can enforce different levels of security for different purposes or for different persons or organizations. Step 6: Authenticating the card-holder. This can be done by either requiring the cardholder to enter a PIN (personal identification number) or some sort of biometric information (for example; fingerprints, retina scan or signature dynamics). The card keeps the relevant information to make a comparison in a secret area. It can make the comparison without divulging to the cardholder the data it holds for the authentication procedure.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
