Incremental improvements from 1969 thru 1973 enabled developing and selling implementations of what became known as the ] (UPC). The narrow magnetic stripe in the center of the card was applied using a magnetic slurry paint. The heat of the iron was just high enough to bond the tape to the card.īack of early magnetic striped encoded paper card. When he explained the source of his frustration, inability to get the tape to "stick" to the plastic in a way that would work, she suggested that he use the iron to melt the stripe on. As he entered his home his wife was ironing clothing. After a frustrating day in the laboratory, trying to get the right adhesive, he came home with several pieces of magnetic tape and several plastic cards. The tape strip either warped or its characteristics were negativelty affected by the adhesive. He tried, unsuccessfully, and produced unacceptable results. In 1969 an IBM engineer had the idea of attaching a piece of magnetic tape, the predominant storage medium at the time, to a plastic card base. Magnetic storage was known from World War II and computer data storage in the 1950s. A stripe of cellophane magnetic tape is fixed to a piece of cardboard with clear adhesive tape The first prototype of magnetic stripe card created by IBM in the late 1960s. There are several virtual card issuing companies located in different geographical regions, such as DiviPay in Australia and Privacy in the USA. On Google released its own version of a cloud hosted Google Wallet which contains digital cards - cards that can be created online without having to have a plastic card in first place, although all of its merchants currently issue both plastic and digital cards. As technological progress emerged in the form of highly capable and always carried smartphones, handhelds and smartwatches, the term "digital card" was introduced. In 1960 IBM used the magnetic tape to develop a reliable way of securing magnetic stripes to plastic cards, the most common identification and payment method to date. They also provide the standards for financial cards, including the allocation of card number ranges to different card issuing institutions.

A number of International Organization for Standardization standards, ISO/IEC 7810, ISO/IEC 7811, ISO/IEC 7812, ISO/IEC 7813, ISO 8583, and ISO/IEC 4909, now define the physical properties of the card, including size, flexibility, location of the magstripe, magnetic characteristics, and data formats. In 1960, IBM used the magnetic tape idea to develop a reliable way of securing magnetic stripes to plastic cards, under a contract with the US government for a security system. In the 1950s, magnetic recording of digital computer data on plastic tape coated with iron oxide was invented. Magnetic recording on steel tape and wire was invented by Valdemar Poulsen in Denmark around 1900 for recording audio.
