Google Pay (payment Method)
Google Pay (formerly Android Pay) is a mobile payment service developed by Google to power in-app, online, and in-person contactless purchases on mobile devices, enabling users to make payments with Android phones, tablets, or watches. Users can authenticate via a PIN, passcode, or biometrics such as 3D face scanning or fingerprint recognition. , it is available in 94 countries. Service Google Pay uses near-field communication (NFC) to transmit card information facilitating funds transfer to the retailer. It replaces the credit or debit card chip and PIN or magnetic stripe transaction at point-of-sale terminals by allowing the user to upload these in Google Wallet. It is similar to contactless payments already used in many countries, with the addition of two-factor authentication. The service lets Android devices wirelessly communicate with point of sale systems using a near-field communication (NFC) antenna and host-based card emulation (HCE). When the user makes a ...

Mobile Payment
Mobile payment, also referred to as mobile money, mobile money transfer and mobile wallet, is any of various payment processing services operated under financial regulations and performed from or via a mobile device. Instead of paying with cash, cheque, or credit card, a consumer can use a payment app on a mobile device to pay for a wide range of services and digital or hard goods. Although the concept of using non-coin-based currency systems has a long history, it is only in the 21st century that the technology to support such systems has become widely available. Mobile payments began adoption in Japan in the 2000s and later all over the world in different ways. The first patent exclusively defined "Mobile Payment System" was filed in 2000. In a developing country, mobile payment solutions can be deployed as a means of extending services of financial institutions to the community known as the "unbanked" or " underbanked", which is estimated to be as much as 50 percent of the ...

Host Card Emulation
Host card emulation (HCE) is the software architecture that provides exact virtual representation of various electronic identity (access, transit and banking) cards using only software. Prior to the HCE architecture, near field communication (NFC) transactions were mainly carried out using hardware-based secure elements. HCE enables mobile applications running on supported operating systems to offer payment card and access card solutions independently of third parties while utilising cryptographic processes traditionally used by hardware-based secure elements without the need for a physical secure element. This technology enables the merchants to offer payment cards solutions more easily through mobile closed-loop contactless payment solutions, offers real-time distribution of payment cards and allows for an easy deployment scenario that does not require changes to the software inside payment terminals. History The term "host card emulation" (HCE) was coined in 2012 by Doug Yeager ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point Of Sale
The point of sale (POS) or point of purchase (POP) is the time and place at which a retail transaction is completed. At the point of sale, the merchant calculates the amount owed by the customer, indicates that amount, may prepare an invoice for the customer (which may be a cash register printout), and indicates the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt, as proof of transaction, which is usually printed but can also be dispensed with or sent electronically. To calculate the amount owed by a customer, the merchant may use various devices such as weighing scales, barcode scanners, and cash registers (or the more advanced "POS cash registers", which are sometimes also called "POS systems"). To make a payment, payment terminals, touch screens, and other hardware and software options are avail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-factor Authentication
Multi-factor authentication (MFA; two-factor authentication, or 2FA) is an electronic authentication method in which a user is granted access to a website or Application software, application only after successfully presenting two or more distinct types of evidence (or Authentication#Authentication factors, factors) to an authentication mechanism. MFA protects personal data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password. Usage of MFA has increased in recent years. Security issues which can cause the bypass of MFA are #Fatigue attack, fatigue attacks, phishing and SIM swap scam, SIM swapping. Accounts with MFA enabled are significantly less likely to be compromised. Authentication factors Authentication takes place when someone tries to log into a computer resource (such as a computer network, device, or application). The resource requires ...

Point-of-sale Terminal
A payment terminal, also known as a point of sale (POS) terminal, credit card machine, card reader, PIN pad, EFTPOS terminal (or by the older term as PDQ terminal which stands for "Process Data Quickly"), is a device which interfaces with payment cards to make electronic funds transfers. The terminal typically consists of a secure keypad (called a PINpad) for entering PIN, a screen, a means of capturing information from payments cards and a network connection to access the payment network for authorization. A payment terminal allows a merchant to capture required credit and debit card information and to transmit this data to the merchant services provider or bank for authorization and finally, to transfer funds to the merchant. The terminal allows the merchant or their client to swipe, insert or hold a card near the device to capture the information. They are often connected to point of sale systems so that payment amounts and confirmation of payment can be transferred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Stripe Card
The term digital card can refer to a physical item, such as a memory card on a camera, or, increasingly since 2017, to the digital content hosted as a virtual card or cloud card, as a digital virtual representation of a physical card. They share a common purpose: identity management, credit card, debit card or driver's license. A non-physical digital card, unlike a #Magnetic stripe card, magnetic stripe card, can Emulator, emulate (imitate) any kind of card. A smartphone or smartwatch can store content from the card issuer; discount offers and news updates can be transmitted wirelessly, via Internet. These virtual cards are used in very high volumes by the mass transit sector, replacing paper-based tickets and the earlier magnetic strip cards. History Magnetic recording on steel tape and wire was invented by Valdemar Poulsen in Denmark around 1900 for recording audio. In the 1950s, magnetic recording of digital computer data on plastic tape coated with iron oxide was invente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chip And PIN
EMV is a payment method based on a technical standard for smart payment cards and for payment terminals and automated teller machines which can accept them. EMV stands for " Europay, Mastercard, and Visa", the three companies that created the standard. EMV cards are smart cards, also called chip cards, integrated circuit cards, or IC cards, which store their data on integrated circuit chips, in addition to magnetic stripes for backward compatibility. These include cards that must be physically inserted or "dipped" into a reader, as well as contactless cards that can be read over a short distance using near-field communication technology. Payment cards which comply with the EMV standard are often called chip and PIN or chip and signature cards, depending on the authentication methods employed by the card issuer, such as a personal identification number (PIN) or electronic signature. Standards exist, based on ISO/IEC 7816, for contact cards, and based on ISO/IEC 14443 for con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debit Card
A debit card, also known as a check card or bank card, is a payment card that can be used in place of cash to make purchases. The card usually consists of the bank's name, a card number, the cardholder's name, and an expiration date, on either the front or the back. Many new cards now have a chip on them, which allows people to use their card by touch (contactless), or by inserting the card and keying in a PIN as with swiping the magnetic stripe. Debit cards are similar to a credit card, but the money for the purchase must be in the cardholder's bank account at the time of the purchase and is immediately transferred directly from that account to the merchant's account to pay for the purchase. Some debit cards carry a Stored-value card, stored value with which a payment is made (prepaid cards), but most relay a message to the cardholder's bank to withdraw funds from the cardholder's designated bank account. In some cases, the payment card number is assigned exclusively for use on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-field Communication
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s. The NFC Forum has helped define and promote the technology, setting standards for certifying device compliance. Secure communications are available by applying encryption algorithms as is done for credit cards and if they fit the criteria for being considered a personal area network. ...
