Credit Card
A credit card can be described as the clichéd plastic money, as it is a plastic card, with a magnetic strip behind, which aids the transfer of data. These cards are issued to a user from a credit union or bank, allowing the user to buy through relevant vendors or take a cash advance. All cards are designed as per the ISO/IEC 7810 as ID -1., which is 85.60 x 53.90mm.
Concept or Principles of a credit card
The credit card enters the user into a loop, which caters one line of cash transfer to the user, through which he borrows the money under the promise of returning it. Unlike other cards, the user is allowed to have a static or constant debt, on which he pays the interest decided, which is certainly more than any other forms of debt.
Interest Rates/ System of Back payments
The banks or the credit unions waiver interest if the entire payment is made within the grace period & in circumstances where the user cannot refund the balance, then interest is calculated starting from the day of purchase, since when the money has been flowing to the present date on the entire , actual amount of purchase.
Therefore if the user bought stuff for Rs 500 on a certain date and carried a debt of Rs 10 beyond the stipulated period, then interest will be calculated from the date when the user bought the stuff, on the entire Rs 500, till the present date.
Formula for calculating Interest in use of a credit card
The standard formula used everywhere is as follows:-
APR/100 x ABD/365 x the number of days.
APR: Annual Percentage Rate
ABD: Average Daily Balance
Great new To the Users
◦ The basic benefit to the user is that of convenience
◦ No calculation of basic balance before credit, however shouldn’t exceed the credit line determined.
◦ Better fraud prevention than the counterpart cards.
Variants
Charge cards : Require the entire debit to be paid by the end of the month
Debit cards: Can be used as currency by the user, using the actual balance and no credit
