The data stored on a credit or debit card is stored not only in the metallic chip - but also on a magnetic strip on the rear of the card. Magnetic card readers read the data from the strip on the card, instead of the embedded chip.
A smart card provides facilities to secure data and is a part of encryption hardware that helps secure data where privacy and security of this data is paramount (like corporate data and day-to-day transaction data when a person makes a purchase online or in-store with their credit card).

Short answer: No. Long answer: All data is automatically stored in SD cards, unless there isn't one or one has altered the settings. When one purchases a new SD card, all the previously recorded data is stored in the old memory card. To obtain the data for the previous SD card, one has to transfer the files. So when one puts in a new SD card, the new data will be stored in the new SD card.

The data pertaining to a single card - is a record. The data relating to more than one card for the same customer - is a file.
Electromagnets apply a magnetic field to encode data onto the magnetic stripe of a credit card. The magnetic stripe contains tiny magnetic particles that are oriented to represent data. When the card is swiped through a card reader, the electromagnet within the reader changes the orientation of these particles, allowing the data to be read.
Credit cards are an application of smart card.Credit cards are either smart card or magnetic strip card.A smart card is a card which have an IC chip to process the data/ Smart card have the capability to process the data.
