Digital card
The term digital card can refer to a physical item, such as a memory card on a camera, or, increasingly since 2017, to the digital content hosted as a virtual card or cloud card, as a digital virtual representation of a physical card. They share a common purpose: identity management, credit card, debit card or driver's license. A non-physical digital card, unlike a magnetic stripe card, can emulate (imitate) any kind of card.
A smartphone or smartwatch can store content from the card issuer; discount offers and news updates can be transmitted wirelessly, via Internet. These virtual cards are used in very high volumes by the mass transit sector, replacing paper-based tickets and the earlier magnetic strip cards.
Magnetic recording on steel tape and wire was invented by Valdemar Poulsen in Denmark around 1900 for recording audio. In the 1950s, magnetic recording of digital computer data on plastic tape coated with iron oxide was invented. In 1960, IBM built upon the magnetic tape idea and developed a reliable way of securing magnetic stripes to plastic cards, as part of a contract with the US government for a security system. 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 such cards, including size, flexibility, location of the magstripe, magnetic characteristics, and data formats. Those standards also specify characteristics for financial cards, including the allocation of card number ranges to different card issuing institutions.
As technological progress emerged in the form of highly capable and always carried smartphones, handhelds and smartwatches, the term "digital card" was introduced.
On May 26, 2011 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. There are several virtual card issuing companies located in different geographical regions, such as Weel in Australia and Privacy in the USA.
A magnetic stripe card is a type of card capable of storing data by storing it on magnetic material attached to a plastic card. A computer device can update the card's content. The magnetic stripe is read by swiping it past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets. They may also contain a radio frequency identification (RFID) tag, a transponder device and/or a microchip mostly used for access control or electronic payment.
Magnetic storage was known from World War II and computer data storage in the 1950s.
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. He tried it, but the result was unsatisfactory. Strips of tape warped easily, and the tape's function was negatively affected by adhesives he used to attach it to the card. After a frustrating day in the laboratory trying to find an adhesive that would hold the tape securely without affecting its function, he came home with several pieces of magnetic tape and several plastic cards. As he entered his home his wife was ironing clothing. When he explained the source of his frustration – inability to get the tape to "stick" to the plastic so that it would not come off, but without compromising its function – she suggested that he use the iron to melt the stripe on. He tried it and it worked. The heat of the iron was just high enough to bond the tape to the card.
