Plastic cards store information using a magnetic stripe, a bar code, or a microchip embedded within the card. The magnetic stripe contains encoded data that can be read by swiping the card through a magnetic card reader. Bar codes, on the other hand, store information in a series of lines of varying widths that can be scanned by a barcode reader. Lastly, microchips store information digitally and can be read by inserting the card into a card reader or tapping it on a contactless reader.
Plastic cards store information through the use of magnetic stripes, embedded microchips, or printed barcodes. These technologies allow data to be encoded onto the card, which can then be read and interpreted by compatible card readers or scanning devices.
Plastic cards store information through the use of magnetic stripes, embedded chips, or barcode systems.
