Work to convert to a second-generation electronic fare system (AFC 2.0) began in 2017. The first public phase of the conversion – contactless card and smartphone payments on the subway and bus systems – was launched on August 1, 2024. Second-generation CharlieCards, a new mobile app, and new fare machines are expected to be placed in service in 2025, with the system extended to commuter rail and ferry in 2026.

Etymology

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.{{Cite magazine |title=The Kingston Trio |url=https://www.billboard.com/artist/the-kingston-trio/chart-history/hsi/ |magazine=Billboard |access-date=2020-10-26}}{{Cite news |last=Seelye |first=Katharine Q. |date=2019-02-05 |title=Jacqueline Steiner, 94, Lyricist Who Left Charlie on the M.T.A., Dies (Published 2019) |language=en-US |work=The New York Times |url=https://www.nytimes.com/2019/02/05/obituaries/jacqueline-steiner-dead.html |access-date=2020-10-26 |issn=0362-4331}} 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.{{cite news |author=Dig Staff |title=Forever, 'Neath the Streets of Boston |publisher=The Weekly Dig |url=http://www.weeklydig.com/articles/what_it_is_36/ |access-date=2006-08-09}}{{dead link|date=May 2016|bot=medic}}{{cbignore|bot=medic}}

File:MBTA Contactless Fare Reader on Type 7 Green Line train.jpg

In November 2017, the MBTA Fiscal and Management Control Board approved a $723 million contract with Cubic Corporation to 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.[https://www.wbur.org/news/2017/11/20/charliecards-may-be-on-their-way-out MBTA Awards $723M Contract For Overhaul Of Fare Collection] Public meetings on the new system were held in 2017 and 2018,[https://mbta.com/projects/fare-transformation Fare Transformation] but then stopped in 2019[https://www.wgbh.org/news/local-news/2019/12/05/mbtas-automatic-fare-collection-20-where-did-it-go MBTA's Automatic Fare Collection 2.0 — Where Did It Go?] until a revised plan was announced in December 2019.

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.

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.{{Cite web|date=1 February 2005|title=T tests its card-based fare system to mixed reviews|url=http://www.newspapers.com/image/443237623/|access-date=2021-05-11|website=Newspapers.com|language=en}}{{Cite web|date=16 January 2005|title=Charlies wanted|url=http://www.newspapers.com/image/443551242/|access-date=2021-05-11|website=Newspapers.com|language=en}} Tickets are inserted into a slot in the gate or farebox, the fare is deducted, and the ticket is returned to the rider.{{Cite web|date=28 August 2005|title=Conversion confusion|url=http://www.newspapers.com/image/443731236/|access-date=2021-05-11|website=Newspapers.com|language=en}}

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.{{cite web |url=http://www.mbta.com/riding_the_t/bikes/ |title=Bikes on the T |author=Massachusetts Bay Transportation Authority |access-date=2013-02-05 |archive-url=https://web.archive.org/web/20170925052309/http://www2.mbta.com/riding_the_t/bikes/ |archive-date=2017-09-25 |url-status=dead }}

Some riders also qualify for free or reduced fare.

Children under the age of 11, people who are Legally Blind, uniformed military personnel, uniformed police officers, uniformed firefighters and select government officials all ride free. Legally Blind people may request a Blind Access CharlieCard. All other non-fare-paying riders are let in by MBTA personnel - often upon presentation of ID.

People with certain disabilities, people on Medicare, people 65 and over, some middle and high school students in participating schools, and people 18–25 with low income are eligible for a reduced fare.

To manage the volume, 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.{{cite press release|title=Show-N-Go Continues Along the Green Line|publisher=Massachusetts Bay Transportation Authority|date=2006-09-01|url=http://www.mbta.com/insidethet/press_releases_details.asp?ID=1142|access-date=2006-12-29|url-status=dead|archive-url=https://web.archive.org/web/20051217181340/http://www.mbta.com/insidethet/press_releases_details.asp?ID=1142|archive-date=December 17, 2005}}{{Cite web|date=30 June 2002|title=Pilot plan keeping Green Line on track|url=http://www.newspapers.com/image/442523967/|access-date=2021-05-21|website=Newspapers.com|language=en}} 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.{{Cite web|date=9 July 2006|title=Green Line's 'Show 'n Go' offers easy way to evade fares|url=http://www.newspapers.com/image/443821774/|access-date=2021-05-21|website=Newspapers.com|language=en}} 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.{{cite news|last=Daniel|first=Mac|date=2006-12-29|title=Free rides will halt on MBTA|page=B1|publisher=The Boston Globe|url=http://www.boston.com/news/local/massachusetts/articles/2006/12/29/free_rides_will_halt_on_mbta/|access-date=2006-12-29}}

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.{{cite news|last=Moskovitz|first=Eric|date=2012-05-30|title=Free rides on Green Line end, T hopes|publisher=The Boston Globe|url=http://articles.boston.com/2012-04-29/news/31478116_1_fare-evasion-free-rides-green-line|url-status=dead|access-date=2012-07-21|archive-url=https://archive.today/20130118084548/http://articles.boston.com/2012-04-29/news/31478116_1_fare-evasion-free-rides-green-line|archive-date=2013-01-18}} In 2016, the policy changed to an all-door boarding during busy hours and front-door-only boarding during off-peak hours.{{cite web|last1=Authority|first1=Massachusetts Bay Transportation|title=MBTA Studies, Addresses Green Line Fare Collection Issues < News < MBTA - Massachusetts Bay Transportation Authority|url=https://www.mbta.com/news/2460|access-date=3 November 2017|website=mbta.com|language=en}}{{Cite web|date=26 April 2016|title=T says uncollected fares, evasion costing it millions annually|url=http://www.newspapers.com/image/444603983/|access-date=2021-05-21|website=Newspapers.com|language=en}}

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 (POP) system. The first POP segment opened in March 2022, with the inauguration of service to Union Square station on the Green Line Extension.

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.Cf.

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,[https://www.defcon.org/html/defcon-16/dc-16-speakers.html DEFCON 16 Speaker and Talk Abstract list] {{webarchive|url=https://web.archive.org/web/20151105132606/https://www.defcon.org/html/defcon-16/dc-16-speakers.html |date=November 5, 2015 }} - August 8, 2008 but were stopped after a federal lawsuit was filed against them by the MBTA, which resulted in a restraining order being issued.McGraw-Herdeg, Michael and Vogt, Marissa, [http://tech.mit.edu/V128/N30/subway.html "Students’ subway security talk canceled by court order"] {{webarchive|url=https://web.archive.org/web/20160318232330/http://tech.mit.edu/V128/N30/subway.html |date=March 18, 2016 }}, MIT Tech newspaper, August 8, 2008[https://www.theregister.co.uk/2008/08/09/defcon_speakers_sued/ Defcon Speakers Sued] {{webarchive|url=https://web.archive.org/web/20160305013349/https://www.theregister.co.uk/2008/08/09/defcon_speakers_sued/ |date=March 5, 2016 }} However, their presentation had already been published by DEFCON before the complaint was filed.{{cite news|url=http://www.efluxmedia.com/news_EFF_to_Fight_Order_Forcing_Students_to_Cancel_Subway_Hacking_Presentation_22006.html|title=EFF to Fight Order Forcing Students to Cancel Subway Hacking Presentation|publisher=Efluxmedia|date=August 12, 2008|url-status=dead|archive-url=https://web.archive.org/web/20080821051245/http://www.efluxmedia.com/news_EFF_to_Fight_Order_Forcing_Students_to_Cancel_Subway_Hacking_Presentation_22006.html|archive-date=August 21, 2008}} On August 19, the court ruled the students could give their presentation.[https://news.yahoo.com/s/nm/20080819/tc_nm/massachusetts_hackers_dc_2 Judge backs hackers in Boston subway dispute]{{dead link|date=November 2016 |bot=InternetArchiveBot |fix-attempted=yes }}

In 2022, it was revealed that the NFC chip in some Android smartphones could interact with CharlieCards, including duplicating data from one card to a blank card. The MBTA indicated that its software systems detected a small number of such duplicated cards – about ten per month – which were then deactivated.{{cite news |url=https://www.bostonglobe.com/2022/12/08/business/your-charliecard-can-be-hacked-by-an-android-phone-mbta-admits/ |title=Your CharlieCard can be hacked by an Android phone, MBTA admits |newspaper=The Boston Globe |date=December 8, 2022 |first=Hiawatha |last=Bray |archiveurl=https://web.archive.org/web/20221208220545/https://www.bostonglobe.com/2022/12/08/business/your-charliecard-can-be-hacked-by-an-android-phone-mbta-admits/ |archivedate=December 8, 2022}}

In 2023, four Medford Vocational Technical High School students found new vulnerabilities in MiFARE Classic that allowed them edit values on CharlieCards. This included adding anywhere between $0 and $327.67, as well as making employee cards. They presented their findings at DEF CON 31 with MBTA approval.{{Cite magazine |last=Greenberg |first=Andy |title=Teens Hacked Boston Subway Cards to Get Infinite Free Rides—and This Time, Nobody Got Sued |language=en-US |magazine=Wired |url=https://www.wired.com/story/mtba-charliecard-hack-defcon-2023/ |access-date=2023-08-22 |issn=1059-1028}}{{Cite conference |url=https://media.defcon.org/DEF%20CON%2031/DEF%20CON%2031%20presentations/Matthew%20Harris%20Zachary%20Bertocchi%20Scott%20Campbell%20Noah%20Gibson%20-%20Boston%20Infinite%20Money%20Glitch%20Hacking%20Transit%20Cards%20Without%20Ending%20Up%20In%20Handcuffs.pdf |title=Boston Infinite Money Glitch: Hacking Transit Cards Without Ending Up In Handcuffs |access-date=2024-02-08}}
