In the summer of 2018, the DC One Card Kids Ride Free program was replaced by the SmarTrip Kids Ride Free Program due to difficulties in activating the DC One Cards. All students who live in the District of Columbia, attend a public, charter, or private school in the District of Columbia, and are between the ages of 5 and 21 are eligible for a Kids Ride Free SmarTrip Card. The Kids Ride Free Card, a normal SmarTrip card with a large silver Kids Ride Free sticker on it, allows students to ride the Washington Metro, Metrobus, and the DC Circulator for free. The DC One Card Program officially terminated on October 1, 2018. Design On the front of the standard SmarTrip card is a stylized picture of a Metrorail car and Metrobus in front of representations of the Washington Monument, United States Capitol, and stylized versions of classical architecture found in Washington, D.C. The Metro logo appears in the bottom left. A "Senior" SmarTrip is also available that automatically calculates applicable discounted fares for senior citizens (age 65+). The design is identical to the standard SmarTrip except that the card is printed in shades of bright yellow and brown, instead of blue and green. Since the Senior SmarTrip allows for discounted fares, the card may only be purchased in person with a valid ID from a Metro sales office or authorized vendor. On March 27, 2016, Metro unveiled a new SmarTrip card design, to celebrate the 40th anniversary of the Metrorail system opening. Beginning November 2016, Metro Access cards, which permit use of Metro Access Paratransit and free trips on Metrobus and Metrorail, were replaced with a special personalized SmarTrip card with the user's photograph and the Metro Access logo appearing on the front of the card. A companion SmarTrip card is included to allow a companion to also ride free along with the disabled person. Promotional designs The first two promotional SmarTrip cards were issued in 2008 to commemorate the opening of the newly built stadium of the Washington Nationals, Nationals Park. Special SmarTrip cards commemorating the inauguration of President Barack Obama were issued in January 2009 and 2013. In July 2013, a special July 4 commemorative SmarTrip card was introduced. In June 2014, Metro celebrated the 125th anniversary of the National Zoo by issuing commemorative SmarTrip cards featuring "popular zoo baby residents." In July 2014, a commemorative
