Digital Ticket
A digital ticket is a virtual instance of a ticket which represents the digitization of rights to claim goods or services. Criteria A digital ticket must fulfill the following criteria: * Secure (unable to alter or counterfeit) * Portable (physical independence) * Off-line capable * Wide acceptability (In order to have the ticket generally accepted, some level of trust is needed.) * User-friendly In addition, another three requirements are also important for digital tickets, they are: * Viewable :The terms and description of the service should be objectively understood by both the service provider and consumer or owner, so the value of the ticket can be determined. Moreover, this is an essential property to trace the digital ticket. * State manageable :Tickets may also have a payment status, i.e., paid or unpaid, and/or reservation status, e.g., waiting list, reserved, or canceled. The status may be changed dynamically. In addition, the ticket ownership can be rewritten when t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtuality
Virtual reality (VR) is a Simulation, simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets ...

Ticket (admission)
A ticket is a voucher that indicates that an individual is entitled to admission to an event or establishment such as a theatre, amusement park, or tourist attraction, or has a right to travel on a vehicle, such as with an airline ticket, bus ticket or train ticket. An individual typically pays for a ticket, but it may be free of charge. A ticket may serve simply as proof of entitlement or reservation. A ticket may be valid for any seat (called "free seating" or "open seating") or for a specific one (called "allocated seating" or "reserved seating"). Overview Members of the public can buy a ticket at a ticket window or counter, called a box office in the entertainment industry (this term is also used for the total receipts), or in some cases online or by telephone. The ticket check may also be located at the box office, or it may be elsewhere. Tickets may also be available from resellers, which typically are commercial enterprises that purchase tickets in bulk and resell t ...

(n.d.). Definition of 'digitize'. Retrieved December 15, 2021, from https://www.collinsdictionary.com/dictionary/english/digitize The result is the representation of an object, image, sound, document, or signal (usually an analog signal) obtained by generating a series of numbers that describe a discrete set of points or samples. The result is called '' digital representation'' or, more specifically, a '' digital image'', for the object, and ''digital form'', for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numerica ...

Association For Computing Machinery
The Association for Computing Machinery (ACM) is a US-based international learned society for computing. It was founded in 1947 and is the world's largest scientific and educational computing society. The ACM is a non-profit professional membership group, claiming nearly 110,000 student and professional members . Its headquarters are in New York City. The ACM is an umbrella organization for academic and scholarly interests in computer science ( informatics). Its motto is "Advancing Computing as a Science & Profession". History In 1947, a notice was sent to various people: On January 10, 1947, at the Symposium on Large-Scale Digital Calculating Machinery at the Harvard computation Laboratory, Professor Samuel H. Caldwell of Massachusetts Institute of Technology spoke of the need for an association of those interested in computing machinery, and of the need for communication between them. ..After making some inquiries during May and June, we believe there is ample interest to ...

Smart Card
A smart card, chip card, or integrated circuit card (ICC or IC card) is a physical electronic authentication device, used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are contactless, and some are both. Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, mobile phones (SIM), public transit, computer security, schools, and healthcare. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Numerous nations have deployed smart cards throughout their populations. The universal integrated circuit card, or SIM card, is also a type of smart card. , 10.5billion smart card IC chips are manufactured annually, including 5.44billion SIM card IC chips. Hist ...

Ecash
Ecash was conceived by David Chaum as an anonymous cryptographic electronic money or electronic cash system in 1983. It was realized through his corporation Digicash and used as micropayment system at one US bank from 1995 to 1998. Design Chaum published the idea of anonymous electronic money in a 1983 paper; eCash software on the user's local computer stored money in a digital format, cryptographically signed by a bank. The user could spend the digital money at any shop accepting eCash, without having to open an account with the vendor first, or transmitting credit card numbers. Security was ensured by public key digital signature schemes. The RSA blind signatures achieved unlinkability between withdrawal and spend transactions. Depending on the payment transactions, one distinguishes between on-line and off-line electronic cash: If the payee has to contact a third party (e.g., the bank or the credit-card company acting as an acquirer) before accepting a payment, the system is cal ...

Electronic Ticket
An electronic ticket is a method of ticket entry, processing, and marketing for companies in the airline, railways and other transport and entertainment industries. Airline ticket E-tickets in the airline industry were devised in about 1994, and have now largely replaced the older multi-layered paper ticketing systems. Since 1 June 2008, it has been mandatory for IATA members to use e-ticketing. Where paper tickets are still available, some airlines charge a fee for issuing paper tickets. When a reservation is confirmed, the airline keeps a record of the booking in its computer reservations system. Customers can print out or may be provided with a copy of a e-ticket itinerary receipt which contains the record locator or reservation number and the e-ticket number. It is possible to print multiple copies of an e-ticket itinerary receipt. Besides providing itinerary details, an e-ticket itinerary receipt also contains: * An official ticket number (including the airline's 3-digit t ...
