CharlieCard
The CharlieCard is a contactless smart card used for fare payment for transportation in the Boston area. It is the primary payment method for the Massachusetts Bay Transportation Authority (MBTA) and several regional public transport systems in the U.S. state of Massachusetts. The card was introduced on December 4, 2006 to enhance the technology of the transit system and eliminate the burden of carrying and collecting tokens. It replaces the metal token, that last of which was sold at Government Center station on December 6, 2006. It is named after a fictional character in the folk song "M.T.A.", often  called "Charlie on the MTA", which concerns a man forever trapped on the Boston subway system – then known as the Metropolitan Transit Authority (MTA) – because he cannot pay the 5-cent surcharge required to leave the train. In 2022, the original CharlieCard system will be replaced during the "Automated Fare Collection 2.0" project, a system similar to the London Oyster Card. The new system will allow payments with contactless cards and smartphones, as well as new CharlieCards. History. The CharlieCard is named after the lead character in the 1948 protest folk music song, "M.T.A.". The song was written to  protest a fare increase in the form of an extra five cent exit fare for longer rides and was later made popular by the Kingston Trio in 1959. One of the rejected names for the farecard system was "The Fare Cod", a pun on both the way locals might pronounce "Card" and the fish that was once integral to the Massachusetts economy, and also a reference to other transit cards named for ocean animals, such as London's Oyster and Hong Kong's Octopus. Another rejected name was T Go card with the T being the symbol for the MBTA . CharlieCards work on the MBTA's subway and bus services, most of which were converted in 2006. Token sales ended on December 6, 2006. The final fare-controlled station to be converted was Fields Corner station on December 22, 2006. They were originally expected to be usable on MBTA commuter rail and ferry boat services by December 2008, with testing on the Commuter Rail originally planned for summer 2008. However, testing had been pushed back to 2009, and full implementation had not been expected until 2011. By 2012, the MBTA had abandoned plans to accept CharlieCards on the commuter rail  system. On June 22, 2020, a pilot program started accepting CharlieCards on the Fairmount Line, by validation at fare vending machines and obtaining proof of payment. Physical fare media are not used on The RIDE; passengers maintain an account by web site, phone, mail, or in-person visits. CharlieCards were gradually introduced to Massachustts Regional Transit Authorities: MetroWest Regional Transit Authority (October 2010), Brockton Area Transit Authority (March 2011), Lowell Regional Transit Authority (November 2011), Merrimack Valley Regional Transit Authority (branded "Tap and Ride Card"; February 2012), Montachusett Regional Transit Authority (March 2012), Worcester Regional Transit Authority (April 2012), Cape  Ann Transportation Authority, Cape Cod Regional Transit Authority (November 2012), Southeastern Regional Transit Authority (January 2013), and Berkshire Regional Transit Authority (January 2014). Technology. The CharlieCard can store a cash balance and daily, weekly and monthly passes that allow unlimited rides during the set period of time. Passengers use the plastic CharlieCard by tapping it against a target on a gate or a vehicle farebox. When tapped, the gate or farebox either debits the cost of the passenger's ride, verifies that the card has a valid transfer or that the card has a pass that is valid for travel  at the given time and location. Transit riders can add value or a monthly pass to their cards at machines located at MBTA stations and vehicles, MBTA ticket offices, and retail sales terminals at select outlets. Beginning in 2009, CharlieCards could be registered and have passes or money added to them online. The original CharlieCards show no expiration date, but expired three to five years after they were first activated. CharlieCards distributed later had expiration dates printed on them and are valid for ten years, with the exception of Student CharlieCards which expire at the end of the school year  they are issued. Prior to 2021, if a user needed to replace an expired CharlieCard, they had to go to the Downtown Crossing pass sales office during business hours or mail the card to MBTA. Passes and stored value left on an expired card can be moved to the replacement card. In 2021, MBTA announced plans to upgrade fare vending machines to be able to dispense CharlieCards. They also announced plans to have the new machines dispense “tappable” paper CharlieTickets, which can be scanned on future fare card readers that were under testing in 2021. Additionally, the new fare readers  would allow riders to pay using a smartphone or contactless credit card. Smartphone technology. In 2012, MBTA announced plans to introduce tickets that could be purchased and scanned on smartphones. Effect on transit employees. After a shift to CharlieCards, some token collectors were retrained as "Customer Service Agents" (CSAs). In March 2017, the MBTA announced they were planning on privatizing their customer service positions to increase efficiency. The MBTA hired a company called 'Block By Block" and named "Transit Ambassadors". In August 2017, the new Transit Ambassador program was rolled out. As of December 2020, there were 200 Transit Ambassadors  working in the MBTA system. Card types. CharlieTicket. Automated fare collection equipment is also compatible with the MBTA's CharlieTicket, a paper card with a magnetic stripe that operates as a stored-value card or time-period (monthly, weekly, or daily) pass. The MBTA first implemented the stored-value CharlieTicket on the Silver Line in February 2005. Tickets are inserted into a slot in the gate or farebox, the fare is deducted, and the ticket is returned to the rider. Upgraded fare gates and fare vending machined were deployed throughout the system starting in 2020 to allow the magstripe CharlieTickets  to be discontinued on March 31, 2022. Part of the AFC 2.0 project, the new machines use a tappable version of the paper CharlieTicket. Bike CharlieCard. On September 18, 2008, two 150-bike parking cages were made available at the Alewife station, next to the MBTA parking garage. Since then, a number of MBTA stations have been provided with secure, monitored bicycle parking cages. Previously, access to these cages required a free special Bike CharlieCard. However, as of the spring of 2013, any CharlieCard can be registered for bike cage access. Purchase options. When the MBTA transitioned to CharlieCards, they  gave cards to riders for free. The cards gives a discount to CharlieCard users that began with the fare increase that took effect on January 1, 2007, and continued giving discounts with later fare increases. The MBTA continues providing the cards free of charge at pass offices, stations throughout the system and local retailers. Certain types of CharlieCards have reduced fares, including those for senior citizens, disabled citizens and students. CharlieCards can be reloaded, and CharlieTickets can be purchased at Fare Vending Machines (FVMs) in transit stations, and elsewhere in the system, including buses. The fareboxes on buses and light  rail trains accept CharlieCards, CharlieTickets and cash. In 2020, MBTA announced plans to phase out cash payments by 2025. The bulk of the MBTA's vehicles and stations were transitioned to the CharlieCard-compatible system throughout 2006, with Fields Corner the last to be converted on December 22, 2006. Fare Vending Machines are available at stations throughout the system, at Logan International Airport, and inside Fenway Park, and at stations on the Green Line D branch. Proof-of-Payment Validation machines are installed at select stops on the other Green Line branches. Future. Automated Fare Collection 2.0. In November 2017 , the MBTA Fiscal and Management Control Board approved a $723 million contract that would replace the original CharlieCard and CharlieTicket with a new system ("AFC 2.0", for Automated Fare Collection) by 2021, that would allow fare gates to be compatible with contactless payment systems that have since been built into many credit cards and smartphones. To speed boarding, payment readers would be installed at all doors of Green Line trolleys and buses (to allow a proof-of-payment system) and cash-on-board payments would no longer be allowed, requiring customers to load cash onto cards at vending machines  or retailers. It would also be extended to the Commuter Rail, where passengers would tap on and off. Public meetings on the new system were held in 2017 and 2018, but then stopped in 2019 until a revised plan was announced in December 2019. The new plan, costing over $900 million, would roll out more gradually from 2020 to 2024. It would lower CharlieTicket fares to match CharlieCard fares when the paper CharlieTickets start using contactless payments instead of magnetic stripe readers. CharlieCards would no longer be free, but would allow for one trip on a negative balance, and  there would be 1,000 additional points of sale for fare media. On December 16, 2020, the MBTA announced that in Winter 2020-2021, the AFC 2.0 system would roll out in a closed pilot program at Forest Hills and Ruggles stations, and on the 28 and 39 bus routes. This new system uses a contactless CharlieCard that has a simplified design. Criticism. Green Line inefficiency. The Green Line is the most heavily traveled light rail line in the United States. Because of this heavy ridership, in 2002, selected stops on the Green Line the MBTA implemented a pilot system known  as Show-N-Go, which allowed riders to flash their monthly passes and enter through the rear doors of a train, reducing congestion at the front door. This system worked when monthly passes were on paper tickets, as each month's pass differed from the previous month, but became easier to evade when MBTA riders began storing monthly passes on CharlieCards, as passes held this way were harder to verify visually. The MBTA installed a proof-of-payment system at certain Green Line stations to reduce the rate of lost fares. Machines were installed that deducted the fare from riders ' cards and gave them a receipt as proof of payment. Additionally, MBTA inspectors with handheld validators were stationed at the busiest stops to deduct money from and verify monthly passes on CharlieCards, also allowing riders to enter through any door. All passengers were required to go to the front of the train and make payment (or show their receipt) to trolley drivers. In July 2012, the MBTA reverted to a "front door only" boarding policy on surface stations outside of peak hours to combat fare evasion. This policy also required passengers getting off the streetcar to walk all the way  to the front of the car to exit. In 2016, the policy changed to a all-door boarding during busy hours and front-door-only boarding during off-peak hours. The "Fare Transformation" project is currently in the process of converting all surface trolley and bus lines to all-door boarding using a proof of payment system. The first POP segment opened in March 2022, with the inauguration of service to Union Square station on the Green Line Extension. Security concerns. Security flaws in the CharlieCard technology were studied and reported in a presentation by Henryk Plötz and Karsten Nohl  at the Chaos Communication Congress in December 2007, which described a partial reverse-engineering of the algorithm used in the MIFARE Classic chip. The MIFARE Classic smartcard from NXP Semiconductors, owned by Philips, was reported as compromised in March 2008 by a group of researchers led by Karsten Nohl, a Ph.D. student in the Department of Computer Science, University of Virginia. In addition, the security used on the mag-stripe CharlieTickets was broken by a team of MIT students. They were scheduled to give a talk about their findings at DEFCON 16 in August 2008, but were stopped after a  federal lawsuit was filed against them by the MBTA, which resulted in a restraining order being issued. However, their presentation had already been published by DEFCON before the complaint was filed. On August 19, the court ruled the students could give their presentation. Other MIT students leveraged the technology behind Charlie Cards in 2013, with the development of Sesame Ring, a wearable ring embedded with an RFID tag that would save riders time in passing through MBTA station faregates. The students formed a company called Ring Theory and funded development of the product using a Kickstarter campaign. The Sesame Ring  can be ordered online, or purchased in the MBTA Gift Store in Cambridge. The product was developed with full cooperation from the MBTA.
