Different Types Of Payment Cards awesome list people being used

The bank or plastic cards are many in the financial transactions people are using. This post tells you about all the payment cards being used in the financial world with some brief description. The below is the list of credit or payment cards of different types.
different credit cards

Top plastic cards being used in payments

  • The purpose o this card is to buy any item within the limit prescribed by banks to the cardholder. These cards can have both Magnetic stripe and Chip cards.
  • Nowadays all banks are issuing credit cards with CHIP and PIN. After entering the PIN by the cardholder, then transaction starts for further processing.

Types of Credit cards

  • Secure credit cards: Cardholder deposits a certain amount of money. When the cardholder goes unpaid, then the card issuer pay from it. Credit Union Cards: 
  • The private Credit Union owners issue credit cards. They usually charge less than what banks will charge Pre-paid cards: They technically equal to Debit cards. They pre-loaded with a certain amount, that amount, you can use your cards 

Debit (ATM, Cash) card

  • It is a relatively new method of payment. It is different from a credit card because the debit cardholder pays with the money available in their bank account, which is debited immediately in real time. 
  • A debit card seems to be more dangerous compared to a credit card because the debit card is directly linked to the bank checking account and usually allows ATM cash withdrawals. 
  • On the other hand, it is more protected by the required two-factor authentication (PIN number plus card itself). The real dangerous element of many branded debit cards is that they can be processed as credit cards, without entering the PIN.

Offline-Debit Cards

They do not require a PIN. Also, these cards differ from normal Debit Cards.

The Gift card. 

  1. It is similar to a debit card but usually does not have the protection provided by a PIN. The gift card is not linked to a bank account and normally "contains" fixed amounts of funds. 
  2. The card itself does not hold any financial information—the point-of-sale (POS) terminal communicates with the gift card provider during payment transactions in order to get authorization. 
  3. Gift cards are less dangerous than credit and debit cards because only fixed, often very limited, amounts of money can be stolen.

The fleet (or proprietary)

  • This card is similar to a credit card but can be used only at particular locations (usually gas stations and convenience stores) and for purchasing only limited types of merchandise (such as fuel and other automobile items). 
  • Fleet cards, even though often issued by major card brands, are less interesting to "bad guys" because they cannot be used for ATM withdrawal, online shopping, or purchases in department or grocery stores.

Co-brand cards

  • A co-branded card is a retail merchant credit card that is issued in partnership with a specific network processor. 
  • Co-branded cards are branded with the logo of the network processor and retailer. 

A private label credit card

It is a store-branded credit card that is intended for use at a specific store.
A private label credit card is a type of revolving credit plan managed by a bank or commercial finance company for either retail or wholesale manufacturers, such as department and specialty stores

Cash Cards

These are Debit cards, Payroll cards, Gift cards, and Pre-paid cards. The credit cards do not come under Cash Cards.

Closed Loop Cards

These cards have imprinted particular company logo. You can only utilize these cards only in that company. These cards do not contain Master or Visa cards logos

Top 100 Hadoop Complex Interview Questions (Part 3 of 4)

These are complex Hadoop interview questions. This is my 3rd set of questions useful for your interviews. 1). What are the features of Standalone (local) mode? Ans). In stand-alone mode there are no daemons, everything runs on a single JVM. It has no DFS and utilizes the local file system. Stand-alone mode is suitable only for running MapReduce programs during development. It is one of the least used environments.

2). What are the features of Pseudo mode?
Ans). The pseudo mode is used both for development and in the QA environment. In the Pseudo mode, all the daemons run on the same machine.

3). Can we call VMs as pseudos?
Ans). No, VMs are not pseudos because VM is something different and pseudo is very specific to Hadoop.

4). What are the features of Fully Distributed mode?

Ans). The fully Distributed mode is used in the production environment, where we have ‘n’ number of machines forming a Hadoop cluster. Hadoop daemons run on a cluster of machines. There is one host onto which Namenod…

Tokenization story you need Vault based Vs Vault-less

The term tokenization refers to create a numeric or alphanumeric number in place of the original card number. It is difficult for hackers to get original card numbers.

Vault-Tokenization is a concept a Vault server create a new Token for each transaction when Customer uses Credit or Debit Card at Merchant outlets 
Let us see an example,  data analysis. Here, card numbers masked with other junk characters for security purpose.

Popular Tokenization ServersThere are two kinds of servers currently popular for implementing tokenization.
Vault-based Vault-less Video Presentation on Tokenization
Vault-based server The term vault based means both card number and token will be stored in a Table usually Teradata tables. During increasing volume of transactions, the handling of Table is a big challenge.
Every time during tokenization it stores a record for each card and its token. When you used a card multiple times, each time it generates multiple tokens. It is a fundamental concept.
So the challe…
