The Go-To card is a contactless smart card meant to be used to pay fares for bus and light rail lines operated by Metro Transit and other transit agencies in the Twin Cities area of Minnesota. It was originally meant to go into service in September 2003 and become the first such system in the United States, but technical difficulties have delayed introduction. Cubic Transportation Systems is working under a contract valued at $16.4 million, but Metro Transit stopped payment at $9.4 million in May 2003 when it became apparent that the rollout would be behind schedule. When it becomes available, the system is expected to significantly speed up boardings on area buses while alleviating wear and tear on existing ticket machines and fare boxes.

Cubic Transportation Systems initially promoted this system as the first contactless smart card installation in the country, but since introduction has been delayed, at least one other system in the U.S. has gone into use. While traditional smart card systems require the card to be swiped through or inserted into a reader, the Go-To card would just require a passenger to tap it against the reading device. This reduces mechanical wear dramatically, and removes the need for readers to be hardened against the sometimes cold and wet climate of Minnesota. Ticket machines on Metro Transit's Hiawatha light rail line were designed with the Go-To card in mind, and were breaking down more often than expected because of the higher-than-anticipated load on the money and ticket handling hardware.

Some Metro Transit employees and selected area riders have been part of a test program, started in the latter half of 2004, using the cards as they go about their daily business. In November 2004 after five months of service, Metro Transit's general manager stated that the devices only achieved 20% reliability.

Cubic has said that the issues delaying introduction are software problems. Frequently, either the reader or the card does not properly detect when it has been used. About 1,000 devices are in place across the system. Blue football-shaped readers are already installed in the area's buses. Software for the central computer system, which handles synchronization and how funds are replenished, was not fully operational until late April 2005.

The underlying technology is Philips' MIFARE system, implementing the ISO 14443A standard.

In November 2005, Metro Transit allowed 18,000 trial users to begin using the Go-To card system, with hopes of rolling out the cards to all users by the fourth quarter of 2006.

On November 15, 2006, Metro Transit unveiled the Go-To card for 2,500 users to use during a trial period lasting until January 31, 2007. Users may pick up the cards at select locations.
