===Telecommunications===
Perhaps the most widely known digitally secure telecommunication device is the [[Subscriber Identity Module|SIM]] (Subscriber Identity Module) card, a device that is embedded in most of the world's cellular devices before any service can be obtained. The SIM card is just the beginning of this digitally secure environment.

The Smart Card Web Servers draft standard (SCWS) defines the interfaces to an [[HTTP server]] in a [[smart card]].<ref>{{cite web|url=http://www.openmobilealliance.org/Technical/release_program/scws_v1_0.aspx|title=Current Releases - The Open Mobile Alliance|work=openmobilealliance.org}}</ref> Tests are being conducted to secure OTA ("over-the-air") payment and credit card information from and to a mobile phone. 
Combination SIM/DVD devices are being developed through Smart Video Card technology which embeds a [[DVD]]-compliant [[optical disc]] into the card body of a regular SIM card.

Other telecommunication developments involving digital security include [[mobile signature]]s, which use the embedded SIM card to generate a legally binding [[electronic signature]].
