Joseph Woodland, Paul McEnroe, Dr. Robert Evans, Bernard Silver, Art Hamburgen, Heard Baumeister and Bill Crouse. 6 The IBM group in Raleigh was competing with RCA, Litton-Zellweger and other companies who were working with the National Retail Merchants Association NRMA to develop a standard optical bar code to be used in the retail industry.The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head.Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets.They may also contain an RFID tag, a transponder device andor a microchip mostly used for business premises access control or electronic payment.
California Barcode Format Software Code To BeIn 1960, IBM used the magnetic tape idea to develop a reliable way of securing magnetic stripes to plastic cards, 2 under a contract with the US government for a security system. A number of International Organization for Standardization standards, ISOIEC 7810, ISOIEC 7811, ISOIEC 7812, ISOIEC 7813, ISO 8583, and ISOIEC 4909, now define the physical properties of the card, including size, flexibility, location of the magstripe, magnetic characteristics, and data formats. They also provide the standards for financial cards, including the allocation of card number ranges to different card issuing institutions. A stripe of cellophane magnetic tape is fixed to a piece of cardboard with clear adhesive tape. He became frustrated because every adhesive he tried produced unacceptable results. The tape strip either warped or its characteristics were affected by the adhesive, rendering the tape strip unusable. 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. As he walked in the door at home, his wife Dorothea was ironing clothing. 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. He tried it and it worked. The heat of the iron was just high enough to bond the tape to the card. ![]() The narrow magnetic stripe in the center of the card was applied using a magnetic slurry paint. Another result of this project was that IBM IRD and IBM Data Processing Division announced on February 24, 1971 the first Magnetic Credit Card Service Center and the IBM 2730-1 Transaction Validation Terminal. Arthur E. Hahn Jr. IBM IRD in Dayton, N.J. Aug 12, 1969 to head up this engineering effort. Other members of the group were David Morgan (Manager), Billy House (Software Developer), William Creeden (Programmer), and E. J. Gillen (Mechanical EngineeringMachining). California Barcode Format Software Software Was DevelopedDue to the limited RAM, the software was developed in 360 Assembler Language. This conversion enabled the 360 computer to monitor and control the entire production process the IRD engineers designed and built. The engineering designbuild effort was carried out in a raised floor secured area of IBM IRD in Dayton, N.J. This tightly secured area with limited access was required because of the sensitivity of the data that would ultimately be used to encode and emboss the credit and ID cards. This was necessary in order to meet the close tolerances required to reliably encode and read the data on the Magnetic Stripe Cards by magnetic writeread heads. The magnetic stripe was encoded with a single track of data utilizing the IBM Delta Distance C Optical Bar Code format. The Delta Distance C Optical Bar Code was developed by the IBM Systems Development Division working at Research Triangle Park in Raleigh North Carolina headed up by George J. Laurer. Other members of the group were N. Joseph Woodland, Paul McEnroe, Dr. Robert Evans, Bernard Silver, Art Hamburgen, Heard Baumeister and Bill Crouse.
