There are two types of smart cards: contact and contactless. Both have an embedded microprocessor and memory. The smart card differs from the proximity card in that the microchip in the proximity card has only one function: to provide the reader with the card's identification number. The processor on the smart card has an embedded operating system and can handle multiple applications such as a cash card, a pre-paid membership card, or an access control card.
Biometric templates may be stored in the memory of readers, limiting the number of users by the reader memory size (there are reader models that have been manufactured with a storage capacity of up to 50,000 templates). User templates may also be stored in the memory of the smart card, thereby removing all limits to the number of system users (finger-only identification is not possible with this technology), or a central server PC can act as the template host. For systems where a central server is employed, known as "server-based verification", readers first read the biometric data of the user and then forward it to the main computer for processing. Server-based systems support a large number of users but are dependent on the reliability of the central server, as well as communication lines.
Your psychic reading can give you the chance to see if you are heading down the right track or if trouble is lurking around the corner. Psychics can reaffirm something you already know, or give you new insights and point of view. After your reading, you will have a greater sense of clarity and control over everything life has been sending your way.
Recognizing a gifted psychic is actually easier than you might think. First of all, psychics will be able to tell you things about yourself that others do not know. This can range from telling you about events in your life to providing you with information about your personality and beliefs. A gifted psychic will also be able to provide you with information without having to ask you several questions first. A scam artist will try to learn as much about you as possible in order to draw conclusions about you and amaze you with his or her “knowledge.”
In the 1-to-1 mode a user must first either present an ID card or enter a PIN. The reader then looks up the template of the corresponding user in the database and compares it with the live scan. The 1-to-1 method is considered more secure and is generally faster as the reader needs to perform only one comparison. Most 1-to-1 biometric readers are "dual-technology" readers: they either have a built-in proximity, smart card or keypad reader, or they have an input for connecting an external card reader.
