Magstripe data is not visible to the naked eye as it is stored magnetically on the magnetic stripe card. The magnetic stripe on the back of a card appears as a black or brown band, typically running horizontally across the card.
The encoded data on the magstripe consists of a series of magnetic fields that represent different types of information. The data is divided into three tracks, each with its own purpose and format.
Track 1: This track is typically used for alphanumeric data and can contain the cardholder’s name, account number, and other identifying information.
Track 2: The second track is the most commonly used track and contains numeric data, including the cardholder’s account number, expiration date, and other relevant information.
Track 3: This track is optional and less commonly used. It can store additional data or be used for specialized purposes, depending on the card’s intended use.
The actual representation of the encoded data is not visible on the stripe itself. It requires a magnetic card reader or specialized equipment to interpret and extract the data from the magnetic fields on the stripe.
To read magnetic card you need to use magstripe card reader.
here are a few examples of data that can be stored on the magstripe of a card:
Track 1: %B1234567890123456^LASTNAME/FIRSTNAME^YYMMDD123456789012345678901234567890?
- B: Start sentinel
- 1234567890123456: Account number
- LASTNAME/FIRSTNAME: Cardholder’s last name and first name
- YYMMDD: Expiration date (year, month, and day)
- 123456789012345678901234567890: Discretionary data
Track 2: ;1234567890123456=YYMMDD123456789012345?
- ;: Start sentinel
- 1234567890123456: Primary account number (PAN)
- YYMMDD: Expiration date (year, month, and day)
- 123456789012345: Discretionary data
