![Baltimore, MD. Statistical data of great value in the future will accumulate in the files of the Social Security Board Records Office. To provide easy means of developing and studying this information, without disturbing the permanent records, acturial cards are reproduced from the original employee master cards. The master card is a [...] salmon pink. The acturial card is a bright green. They are of different colors so they will not be mixed together inadvertently. The photograph above shows a reproducing machine making acturial cards from master cards. The punched master card is placed in one compartment. A blank acturial card is placed in another. When the master card has been automatically carried to the proper position it stops, momentarilly. Meanwhile the blank acturial card is carried to another place in the machine. Electrical impulses cause the machine to punch on the acturial card the same holes, in the same position, as on the master card. The two cards are held in place while the part of the machine holding the acturial card telegraphs back to the part holding the master card to see that the punches in each are identical. Then the cards are released, one is in one pile and the other in another. The whole operation requires a small fraction of a minute](https://cache.getarchive.net/Prod/thumb/cdn4/L3Bob3RvLzE5MzcvMDEvMDEvYmFsdGltb3JlLW1kLXN0YXRpc3RpY2FsLWRhdGEtb2YtZ3JlYXQtdmFsdWUtaW4tdGhlLWZ1dHVyZS13aWxsLWFjY3VtdWxhdGUtNjQwLmpwZw%3D%3D/40/50/webp "Baltimore, MD.
