mobile operating system
in october 2011, the first mobile phones with mastercard paypass and/or visa paywave certification appeared. a paypass or paywave account can be assigned to the embedded secure element and/or sim card within the phones. google pay is an application for devices running google's android os, which allows users to make purchases using nfc, which initially required a physical secure element but this was replaced by host card emulation which was introduced in android 4.4 (kitkat). softcard (formerly known as isis mobile wallet), cityzi and quick tap wallets for example, use a secure sim card to store encrypted personal information. contactless payments with enabled mobile phones still occur on a small scale, but every month an increasing number of mobile phones are certified.
