 There are four steps that MasterCard can take to promotegreater use of its BU and reporting tools by its clients.1) Check the Data at the source:BusinessData usually does not come from one source and in one format alone. Make surethat the source and the type of data that it sends matches. Also, do a basicvalidation right here.Let us say a student’s details aresent from a source for subsequent processing and storage. Make sure that thedetails are correct, right at this point itself.

If the GPA shows as 7, this isclearly over than the 5 points system. So, such data can be discarded orcorrected right here itself without taking it for further processing.2) Check the data transformation:Thisis where the raw data gets processed into business targeted information.·        The source and destination datatypes should match. E.g. You can’t store the date as text.·        Primary key, foreign key, null,default value constraints, etc.

should be intact.·        The ACID properties of source anddestination should be validated, etc.3) Check the data LoadingThe actual scripts that load thedata and testing them would be definitely included in your ETL testing. Thedata storage system, however, has to be validated for the following:·        Performance: As systems become more intricate, there arerelationships formed between multiple entities to make several co-relations.This is great news for data analytics, however, this kind of complexity oftenresults in queries taking too long to retrieve results.

Therefore, performance testing plays an important role here.·        Scalability: Data is only going to increase not decrease.Therefore, tests have to be done to make sure that the size of the growingbusiness and data volumes can be handled by the current implementation or not.This also includes testing the archival strategy too. Basically, you are tryingto test the decision- “What happens to older data and what if I need it?”It is also a good idea to test theother aspects such as its computational abilities, recovery from failure, errorlogging, exception handling, etc.4) BI Report Testing:This is what is considered BusinessIntelligence. But, as you can see from the above, the reports are never goingto be correct, consistent and fast if your preceding layers weremalfunctioning.

Accordingto me, Largerclients will benefit most from MasterCard’s analytics tools because:·        It processes vast amount of datathat would take ages to analyze manually·        It dismisses all sorts of actionableintelligence boundaries, including locations, server logs, and access todifferent markets·        It helps them personalize salesregardless of the number of customers they must attend to·        It saves time and resources·        It provides instant and real-timeanswers in critical moments·        It makes corporate informationaccessible 24/7, and from a variety of devices·        It protects sensitive and enclosedcorporate data·        It helps make accurate predictionsfor the future Ans:Q.3 Tap-and-gocards, also known as wave-to-pay, tap-to-pay or contactless cards, contain acomputer chip and antenna instead of the magnetic stripe on the back oftraditional cards. The technology sends data wirelessly to a nearby terminal,completing purchases with a process called near-field communication, orNFC.Brands that use this technology include Visa payWave, MasterCard PayPass,American Express ExpressPay and Discover Zip.

There are several types of tap payment applications such as SamsungPay, Apple Pay, Android Pay or any bank mobile application thatsupport Contactless. Some suppliers claim that transactions can bealmost twice as fast as a conventional cash, credit, or debit cardpurchase. Because no signature or PIN verification istypically required, contactless purchases are typically limited to small valuesales. Lack of authentication provides a window during which fraudulentpurchases can be made.

Research indicates that consumers are likely to spend moremoney using their cards due to the ease of small transactions. MasterCard saysit has seen “about 25 percent” higher spending by users of its MasterCardContactless-brand RFID credit cards.No, there are no limits to the types of applications thattap & go payments can be used for becauseno signature or PIN verification is typically required,contactless purchases are typically limited to a set maximum amount pertransaction, known as a “floor limit”. Limits may vary between banks.Ans:Q.4 MasterPass is being embraced as paymentmechanism for online purchases of MasterCard’s PayPass digital wallet. With the MasterPass services, payment credentialsentered into the digital wallet will support technologies for payments inbrick-and-mortar stores as well. That means that providers using technologieslike NFC and QR codes at the point of sale can integrate with MasterPass anduse it to store consumer data safely in the cloud, accessing those credentialswhenever a purchase is made.

Advantagesof PayPass:·        Convenient as you just need to “tapand pay” using your credit card or mobile phone without keying in a PIN orsigning a receipt.·        Gives you peace of mind as you areprotected against fraudulent transactions.·        Reduces threat of hackers who mayscan cards and steal valuable information as NFC uses data encryption whensending sensitive information.·        Cost and time efficient for theaverage consumer.·        You do not have to worry with typingerrors (such as incorrectly typing in your PIN) and connection is quicker onthe contactless terminal.·        Retailers no longer have access toyour credit card information.·        You are able to keep track ofrewards and use points for your purchases made in coffee shops or milesredemption.

Some banks even offer cash back and prizes when you use this feature.·        Convenient and quick checkoutpayments mean lesser queues and lining up.Disadvantagesof PayPass:·        Only a few yet have adopted to thistechnology so it might create confusion or frustration among users. Not allconsumers are educated on this technology.

·        Only consumers with smartphones orthose with PayWave/PayPass credit cards can use this technology.·        You may lose your credit card andyour account may be compromised.·        Risk of spyware or malware attacksand other viruses like any computer device in the terminal.·        You can’t change the limit or choosethe limit per transaction as chosen by the bank.

MasterCardmust ensurethat their customers information is encrypted and well protected, this ishurdle that the company must face. So,they must develop the securitysystems to avoid the potential security issues.Ans:Q.5There are many challenges thatMasterCard faces in rolling out smartphone payment systems including the followseven significant hurdles:·        Mobilepayments aren’t seamless·        Mobile payments don’t offer special incentives·        Mobile payment infrastructure is slow to evolve·        EMV transition won’t help mobile payments·        Modern mobile payment experience is inconsistent·        Ingrained behavior is tough to change·        Mobile payment security concernsAccording to me, Mobile paymentsecurity concerns will be most difficult to address because Mobile payments may or may not be more secure thanother forms of payment, but some consumers at least fear that they aren’t andtherefore shy away from using smartphones and wearables at cash registers.All-too-common data breaches at banks, credit card companies, retailers, andothers are widely reported in the media, fueling consumer anxieties.

Thieveshave access to incredibly sophisticated tools to grab consumers’ passwords,login credentials, and other personal data. And despite recent concerns existamong some consumers that smartphones collect too much information about theirpurchases and other activities.
