The Tarjeta de Movilidad Integrada (MI; literal English translation: Integrated Mobility Card) is a contactless smart card introduced in Mexico City in October 2005 as "Tarjeta Metrobús".

It offers interoperability with the Metro, Metrobús, Ecobici, Cablebús, Light train, RTP and Trolleybus systems.

[1] In 1986, the Mexico City Government (then called Distrito Federal), implemented a plastic card called Abono for the STC Metr, this card was used similarly to the paper ticket used but with the difference that it could be reused multiple times, unlike the paper ticket that was usable only once.

On October 17, 2012, the Tarjeta Distrito Federal (literal English translation: Federal District Card) was released along the inauguration of the 12th line of the Mexico City Metro, a line that can only be accessed with the card.

The Integrated Movility card is used by most of the official transportation systems in Mexico City.
