A smart card (SC), chip card, or integrated circuit card, is a card used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are contactless, and some are both. Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, public transit, computer security, schools, and healthcare. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Numerous nations have deployed smart cards throughout their populations.
Mobile payment, also referred to as mobile money, mobile money transfer and mobile wallet, is any of various payment processing services operated under financial regulations and performed from or via a mobile device. Instead of paying with cash, cheque, or credit card, a consumer can use a payment app on a mobile device to pay for a wide range of services and digital or hard goods. Although the concept of using non-coin-based currency systems has a long history, it is only in the 21st century that the technology to support such systems has become widely available.
The Octopus card is a reusable contactless stored value smart card for making electronic payments in online or offline systems in Hong Kong.

It is also used for purposes such as recording school attendance and permitting building access. The cards are used by 98 percent of the population of Hong Kong aged 15 to 64 and the system handles more than 15 million transactions, worth over HK$220 million, every day.
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s.
Suica is a prepaid rechargeable contactless smart card and electronic money system used as a fare card on train lines and other public transport systems in Japan, launched on November 18, 2001, by JR East.

The card is also widely used as electronic money for purchases at stores and kiosks, especially at convenience stores and within train stations. In 2018, JR East reported that Suica was used for 6.6 million daily transactions. As of October 2023, 95.64 million Suica have been issued, and 1.63 million stores accept payment via Suica's digital currency.
The Brussels Metro is a rapid transit system serving a large part of the Brussels-Capital Region of Belgium. It consists of four conventional metro lines and three premetro lines. The metro-grade lines are M1, M2, M5, and M6 with some shared sections, covering a total of 39.9 kilometres (24.8 mi), with 59 metro-only stations. The premetro network consists of three tram lines that partly travel over underground sections that were intended to be eventually converted into metro lines. Underground stations in the premetro network use the same design as metro stations. A few short underground tramway sections exist, so there is a total of 52.0 kilometres (32.3 mi) of underground metro and tram network. There are a total of 69 metro and premetro stations as of 2011.
The Navigo pass is a family of contactless smart cards that can be used for payment in public transportation in Paris and the Île-de-France region. It was first introduced on 1 October 2001. The cards are implemented as contactless smart cards using the Calypso standard, initially with Radio-frequency identification (RFID), then Near-field communication (NFC) since 9 December 2013, and enables authenticated access at turnstiles by scanning the card at an electronic reader. Cards can be loaded with tickets and passes at staffed counters and at ticket vending machines. Since July 2018, they can also be recharged directly using a smartphone. Certain smartphones and smartwatches can be used in place of physical Navigo passes using mobile apps, such as Île-de-France Mobilités, Samsung Wallet, or Apple Wallet, which allow verification at Navigo card readers using NFC functionality.

Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication (NFC) for making secure payments. The embedded integrated circuit chip and antenna enable consumers to wave their card, fob, or handheld device over a reader at the point-of-sale terminal. Contactless payments are made in close physical proximity, unlike other types of mobile payments which use broad-area cellular or Wi-Fi networks and do not involve close physical proximity.

Kolumbus AS, formerly Rogaland Kollektivtrafikk FKF, is the public transportation administration in Rogaland, Norway and organised as a county agency. The agency is responsible for planning, marketing and organising the public transport in Rogaland, including buses and passenger ferries, but does not perform any transport itself. Instead it awards public service obligation (PSO) contracts to independent operators. The agency was created on January 1, 2002 and has 35 employees and offices at Byterminalen in Stavanger. All buses operated in Rogaland are branded as Kolumbus and painted green. Before Kolumbus was created, there were several smaller companies who was responsible for the transport in the different parts of Rogaland. However, because of complications with bus lines not overlapping with each other, the bus companies finally decided to unite and become Kolumbus, or Rogaland Kollektivtrafikk as it is also known as.

The TFI Leap Card is a contactless smart card for automated fare collection overseen by Transport for Ireland (TFI). It was introduced in the Greater Dublin area in 2011 for Luas, DART, Iarnród Éireann and Dublin Bus, but acceptance has significantly expanded, and it is now accepted in cities nationwide and on some longer distance commuter routes. Initially, Leap Cards offered only a pre-paid electronic wallet system for single-trip fares; since May 2014, it has also been possible to load it with weekly, monthly and annual subscriptions. In September 2017, there were over 2.5 million Leap Card users according to the National Transport Authority. The Leap Card is the result of many years' work by the Railway Procurement Agency and the National Transport Authority as part of the rollout of an integrated ticketing scheme for public transport in Dublin city. Fares are generally discounted compared to cash prices, and integrated ticketing is offered in the Dublin area via a flat fare system across all modes of transport. The minimum top-up for the card is currently €5, and it can be topped up via iPhone/Android App, at LUAS or DART ticketing machines, and in convenience stores offering Payzone services.
