Independently, Kunitaka Arimura of the Arimura Technology Institute in Japan developed a similar idea of incorporating an integrated circuit onto a plastic card, and filed a smart card patent in March 1970. In September 1968, Helmut Gröttrup, together with Dethloff as an investor, filed further patents for this identification switch, first in Austria and in 1969 as subsequent applications in the United States, Great Britain, West Germany and other countries. Its primary use was intended to provide individual copy-protected keys for releasing the tapping process at unmanned gas stations. In February 1967, Gröttrup filed the patent DE1574074 in West Germany for a tamper-proof identification switch based on a semiconductor device. The idea of incorporating an integrated circuit chip onto a plastic card was first introduced by two German engineers in the late 1960s, Helmut Gröttrup and Jürgen Dethloff. 1.6.16 Oberthur Technologies, now Idemiaįirst smart card manufactured by Giesecke & Devrient in 1979, already with the finally standardized dimension (ID-1) and a contact area with eight pads (initially on the upper left corner).As of 2015, 10.5 billion smart card IC chips are manufactured annually, including 5.44 billion SIM card IC chips. The universal integrated circuit card, or SIM card, is also a type of smart card. Numerous nations have deployed smart cards throughout their populations. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Applications include identification, financial, mobile phones (SIM), public transit, computer security, schools, and healthcare. Smart cards can provide personal identification, authentication, data storage, and application processing. Others are contactless, and some are both. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. A smart card, chip card, or integrated circuit card ( ICC or IC card) is a physical electronic authorization device, used to control access to a resource.
