RFID Skimming
RFID skimming is a method to unlawfully obtain someone's payment card information using a RFID reading device. How RFID skimming is performed Modern payment cards have a built in chip that transmits the cards' information wirelessly. This is because it is necessary in order to enable contactless payments, which has become increasingly popular during recent years. Criminals can take advantage of this new technology by using a scanner that wirelessly scans the victim's payment card in the same way that a cash register scans it, when making a contactless payment. These scanners are legal and can be bought in regular electronics stores. Most modern mobile phones running Android OS have a built in NFC reader that can be used to unlawfully scan contactless payment cards. A criminal can hide the scanner e.g. inside a glove or a bag, and then place it close to the victim and wirelessly steal the victim's payment card information. With the wirelessly obtained payment card information, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RFID
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in many industries. For example, an RFID tag attached to an automobile during production can be used to track ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contactless Payment
Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication (NFC, e.g. Samsung Pay, Apple Pay, Google Pay, Fitbit Pay, or any bank mobile application that supports contactless) for making secure payments. The embedded integrated circuit chip and antenna enable consumers to wave their card, fob, or handheld device over a reader at the point of sale terminal. Contactless payments are made in close physical proximity, unlike other types of mobile payments which use broad-area cellular or WiFi networks and do not involve close physical proximity. EMV is a common standard used by major credit card and smartphone companies for use in general commerce. Contactless smart cards that function as stored-value cards are becoming popular for use as transit system farecards, such as the Oyster card or RioCard. These can ...

Near-field Communication
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1 in) or less. NFC offers a low-speed connection through a simple setup that can be used to bootstrap more-capable wireless connections. Like other "proximity card" technologies, NFC is based on inductive coupling between two so-called antennas present on NFC-enabled devices—for example a smartphone and a printer—communicating in one or both directions, using a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band using the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 424 kbit/s. The standards were provided by the NFC Forum. The forum was responsible for promoting the technology and setting standards and certifies device compliance. Secure communications are available by applying encryption algorithms as is done for credit cards and if they fit the crite ...

Card Not Present Transaction
A card-not-present transaction (CNP, mail order / telephone order, MO/TO) is a payment card transaction made where the cardholder does not or cannot physically present the card for a merchant's visual examination at the time that an order is given and payment effected. It is most commonly used for payments made over the Internet, but can also be used with mail-order transactions by mail or fax, or over the telephone. Card-not-present transactions are a major route for credit card fraud, because it is difficult for a merchant to verify that the actual cardholder is indeed authorizing a purchase. If a fraudulent CNP transaction is reported, the acquiring bank hosting the merchant account that received the money from the fraudulent transaction must make restitution to the cardholder, which is called a chargeback. This is the opposite of a card present transaction, when the issuer of the card is liable for restitution. Because of the greater risk, some card issuers charge a greater tr ...

Proximity Card
A proximity card or prox card also known as a key card or keycard is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. The proximity cards are part of the contactless card technologies. Held near an electronic reader for a moment they enable the identification of an encoded number. The reader usually produces a beep or other sound to indicate the card has been read. The term "proximity card" refers to the older 125 kHz devices as distinct from the newer 13.56 MHz contactless smartcards. Second generation prox cards are used for mass and distance reading applications. Proximity cards typically have a read range of up to which is the main difference from the contactless smartcard with a range of . The card can often be left in a wallet or purse,Access Control Card Handling Guide https://www.supercircuits.com/media/docs/proxcard_handlin ...

Keycard Lock
A keycard lock is a lock operated by a keycard, a flat, rectangular plastic card. The card typically, but not always, has identical dimensions to that of a credit card or American and EU driver's license. The card stores a physical or digital pattern that the door mechanism accepts before disengaging the lock. There are several common types of keycards in use, including the mechanical holecard, barcode, magnetic stripe, Wiegand wire embedded cards, smart card (embedded with a read/write electronic microchip), RFID, and NFC proximity cards. Keycards are frequently used in hotels as an alternative to mechanical keys. The first commercial use of key cards was to raise and lower the gate at automated parking lots where users paid a monthly fee. Overview Keycard systems operate by physically moving detainers in the locking mechanism with the insertion of the card, by shining LEDs through a pattern of holes in the card and detecting the result, by swiping or inserting a magnetic ...

Automated Teller Machine
An automated teller machine (ATM) or cash machine (in British English) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, balance inquiries or account information inquiries, at any time and without the need for direct interaction with bank staff. ATMs are known by a variety of names, including automatic teller machine (ATM) in the United States (sometimes redundantly as "ATM machine"). In Canada, the term ''automated banking machine'' (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM over ABM. In British English, the terms ''cashpoint'', ''cash machine'' and ''hole in the wall'' are most widely used. Other terms include ''any time money'', ''cashline'', ''tyme machine'', ''cash dispenser'', ''cash corner'', ''bankomat'', or ''bancomat''. ATMs that are not operated by a financial i ...

Aluminum Foil
Aluminium foil (or aluminum foil in North American English; often informally called tin foil) is aluminium prepared in thin metal leaves with a thickness less than ; thinner gauges down to are also commonly used. Standard household foil is typically thick, and heavy duty household foil is typically . The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. Annual production of aluminium foil was approximately in Europe and in the U.S."Foil & Packaging" . The Aluminum Association (USA). in 2003. Approximately 75% of aluminium foil is used for |
Microwave Oven
A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer of a homogeneous, high-water-content food item. The development of the cavity magnetron in the UK made possible the production of electromagnetic waves of a small enough wavelength (microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the "Radarange", it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was introduced by Tappan in 1955, but it was still too large and expensive for general home use. Sharp Corpo ...

Faraday Cage
A Faraday cage or Faraday shield is an enclosure used to block electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after scientist Michael Faraday, who invented them in 1836. A Faraday cage operates because an external electrical field causes the electric charges within the cage's conducting material to be distributed so that they cancel the field's effect in the cage's interior. This phenomenon is used to protect sensitive electronic equipment (for example RF receivers) from external radio frequency interference (RFI) often during testing or alignment of the device. They are also used to protect people and equipment against actual electric currents such as lightning strikes and electrostatic discharges, since the enclosing cage conducts current around the outside of the enclosed space and none passes through the interior.
