A transit pass (North American English) or travel card (British English), often referred to as a bus pass or train pass etc. (in all kinds of English), is a ticket that allows a passenger of the service to take either a certain number of pre-purchased trips or unlimited trips within a fixed period of time.
Depending on the transport network and on how much the pass is used, the pass may offer varying discounts compared with trips that are purchased individually. While transit passes can generally be purchased at full price by anyone wishing to use the services (senior citizens, the disabled, students and some others are often able to get them at a reduced price) many employers, colleges, and universities will subsidize the cost of them, or sometimes the full amount.
Some public transport networks will allow certain types of personnel, including police officers, fire fighters, active military, and their own employees to ride their services free with proper identification and without the need to purchase a pass.
Some common forms of transit passes are:
A "semester ticket" is a student transit pass issued by universities and fachhochschulen in Germany allowing students to travel on the buses, trams, subways, and local trains of the school's home city. The cost of the semester ticket is included in the university's student fees., and it can be used in the state where his university situated. The ticket is valid for transit on the subway (U-Bahn), suburban trains (S-Bahn), street trams, and buses in that state, but is not valid on Intercity-Express trains.
In Vilnius, a travel card is used for the public transport.
Travel card systems are used in most of the local public transport in Norway. In the counties of Oslo and Akershus, reisekort (meaning simply "travel card", formerly Flexus) is used for the T-bane (Metro), tramway and the Municipal bus system. In Sør-Trøndelag, t:kort (meaning "t:card") is used. In Rogaland, Kolumbuskort (meaning "Kolumbus card") is used. In Hordaland, Skysskortet (meaning "Skyss card") is used. In addition, several other counties use similar travel card systems.
A prepaid leap card is available for transport in the greater Dublin area, providing access to LUAS, DART and Dublin Bus services. The card may be topped up online.
In the United Kingdom anyone over the "age of eligibility" and people with certain disabilities travel free on most public buses throughout the country at certain times (typically between 9:30 a.m. to 11:00 p.m. on weekdays and all day on weekends and Bank Holidays) through the English National Concessionary Travel Scheme. Some councils also allow these people to travel free on trains, trams or ferries. This scheme was also introduced in Wales in 2002, in Scotland in April 2006, and later in England. Northern Ireland runs a similar scheme but the age limit is 66.
The "age of eligibility" was 60 until 6 June 2010, but it will increase over ten years to 65, in line with parallel changes to women's eligibility for state old age pension.
Travel card schemes for general public use are currently operated in the United Kingdom in a number of areas including:
Travel card schemes are often supplemented or replaced by stored value cards.
With the Octopus smartcard many transport operators, including bus, minibus and railway companies provide free transfers or discounts on the second leg of the journey. Also, the major bus companies, as well as MTR, the railway operator, offer a discounted flat fare for senior citizens on certain days of the week, at HK$1 and HK$2 respectively.
Prepaid transit passes are moving toward electronic plastic-based or paper-based contactless cards.
Early cards are plastic based and limited only for underground railway trips. For surface transportation they have unlimited trips within a fixed period of time. A passenger has to pay a security deposit of 30 roubles for the card itself. When the pass expires, passenger can recharge it with the same or another type of fare or return the card and get the security deposit back. The card itself expires 90 days after not being recharged. In this case, the security deposit cannot be returned.
In 2010 appeared the first non-rechargeable disposable paper-based electronic transit passes for a certain number amount of trips on trams, trolleybuses and buses. They are sold with a protective foil sticker, which should be removed prior to first use. They are not time-limited except that they expire 30 days after the countrywide or citywide fare changes, which happens usually each 1–2 years.
In 2011 the "Podorozhnik" ("Plantago") cards came to the stage. Their difference from early plastic cards is that they have a conventional area where a fare for specific amount of time (15 days, one month) could be written (the unit is a single ride) and an "electronic wallet" which could be charged with any amount of roubles (the unit is Rouble) with an ability to get a discount - the more rides the cheaper a single ride is. Electronic wallet gets unlocked when a fixed period fare expires. Also they have bigger expiration period after not being recharged (3 years).
Unlimited Ride passes allow travel on all CTA buses and trains with a 1-Day Fun Pass, or 3-day, 7-day or 30-day unlimited-ride passes. The pass, via Ventra, activates the first time the rider uses it and is good for the number of consecutive days shown on the front of the pass. 1-Day($10), 3-Day($20), 7-Day($33), 30-Day($100) 
Greyhound Lines: As from September 30, 2012, the Discovery Pass is no longer available for purchase. The company is thought to feel that 'board-anytime go-anywhere' passes complicate their new business model of "guaranteed reserved seats".
In Martha's Vineyard it is rare to offer an annual pass in addition to passes valid for one, three, seven, or thirty-one days. The cost of an annual pass is $100 for adults and $50 for students. All other types of passes are available at adult prices only.

TransLink offers several types of fare cards priced by the number of zones the user will be in. They are currently priced $91 for 1 Zone, $124 for 2 Zones, and $170 for three zones. Concession and student passes are also available. Books of individual fares (FareSavers) can also be purchased at a slight discount. Individual fares, whether purchased from a ticket machine or a FareSaver dealer, are valid for 90 minutes after either purchase or validation.

While fares for individual trips vary, the Washington Metropolitan Area Transit Authority offers various passes for riding Metrobus and Metrorail. A seven-day regular fare pass for unlimited Metrorail rides is $47, but this cannot be used on buses. A one-day rail-only pass is available for $9.00, but on weekdays, this is not valid until after 9:30 AM. A weekly Metrobus pass is available for $15 at regular fare, and it cannot be used on Metrorail.
Riders of Metrorail and Metrobus can transfer between the two services and enjoy a $0.50 discount if they use an electronic SmarTrip card. Those transferring between any two Metrorail lines can change trains without exiting the faregate, thereby incurring no additional fare or requiring a transfer slip.
Transfers are honored both ways between Metrobus and Montgomery County's Ride-on bus service. Ride-on accepts transfers from Metrorail for an additional 35¢ (waived for senior citizens), but there are no transfers from Ride-on buses to Metrorail.

MARC monthly passes are also honored as fare payment for all Maryland Transit Administration bus, Metro and Light Rail services in the Baltimore area at no extra cost.
The Maryland Transit Administration within the Baltimore area generally charges $1.70 for a single trip on one local bus or train. The agency abolished transfers in 1996 in favor of day passes, which at the time were $3.00 and are currently $4.00. Those taking multi-bus/train trips are encouraged to purchase day passes, which at regular fare, are the cost of two one-way trips plus 30¢. Weekly and monthly passes are also available, and all such passes since 2005 have been called "GO-passes." The only transfers that are allowed in the system without additional fare payment are between the various lines of the light rail.
Winnipeg Transit also offers free transfers with all base fares, and these transfers are valid for up to 60 min from the time of fare payment in what is termed power hour by the agency.
