A stripe of an magnetic tape is reaedrs to a piece of cardboard with clear adhesive tape Magnetic rewwriters was known from World War II Mqgnetic computer data storage in the s. He became frustrated snd 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: He tried it and it worked.

Inthe marketing organization was transferred by IBM DPD back to the Information Records Division in order to begin sales and marketing strategies for the magnetically striped and encoded cards being developed.

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. Bar code encoding developments[ edit ] The IRD engineers first had to develop a reliable process of hot stamping the magnetic stripe to the plastic cards. Other members of the group were N. The code would also be used for production and inventory control of products. Because of the sensitivity of the customer data and the security requirements of banks, insurance companies and others, the manufacturing group decided to leave the entire line in the secured area where it was developed.
Banks, insurance companies, hospitals etc.
They also supplied the data information which was to geaders encoded rerwiters embossed on the cards. This data was supplied to IRD on large 0. This rewritrs of applying the magnetic stripe to the plastic cards was done off line in another area of IBM IRD and not in the secured area. The Magnwtic were then brought into the secured rewrriters and placed in "hoppers" at the beginning of the production line. The tape reels stdip the data were then installed on the modified IBM computer prior to beginning the encoding, embossing and verification of the cards. After the performed a check to verify that all systems and stations were loaded and ready to go, the computer began feeding the Magnetic Striped Plastic Cards from the hoppers at the front end of the production line down a motorized track.
The entire operation was fully automated and controlled by the modified IBM business computer. The line consisted of the following stations and operations: Plastic card feeder station: The cards were fed down a track in single file from card hoppers. The card passed under the read head and the encoded data was sent back to the for verification. Paul company, had just developed the first electronically controlled embossing machine for plastic cards and effectively obsoleted all other mechanical operated embossers. To highlight the embossing. To imprint the embossing on an automatically fed paper roll.
An optical reader station: To read the embossed information off the paper roll and feed it back to the computer for verification. A one card rejection station: If either the encoding or embossing data on the card was not verified by the computer, that one card was rejected.
If both the encoded and embossed data was confirmed by the computer, the card proceeded down the line. A mailer was printed with the name and address of the card holder along with the date and other relevant card information. These mailers were also preprinted and die cut by IRD according to the customers specs and logo requirements and were fed into the line out of boxes in a continuous fan feed method. A card insertion station: Here the card was automatically inserted onto the mailer.
