All QuickFare machines have now been replaced by more modern technology.

Document 6: Contactless payment: 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, e.g. Samsung Pay, Apple Pay, Android Pay, or any bank mobile application that support Contactless) for making secure payments. The embedded 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 mobile payments which use broad-area cellular or WiFi networks and do not involve close physical proximity.

Document 12: Speedpass: Speedpass is a keychain RFID device introduced in 1997 by Mobil Oil Corp. (which merged with Exxon to become ExxonMobil in 1999) for electronic payment. It was originally developed by Verifone. As of 2004, more than seven million people possess Speedpass tags, which can be used at approximately 10,000 Exxon, Mobil and Esso gas stations worldwide. At one point, Speedpass was deployed experimentally in fast-food restaurants and supermarkets in select markets. McDonald's alone deployed Speedpass in over 400 Chicago area restaurants. The test was deemed a failure and McDonald's removed the scanners from all their restaurants in mid-2004. Additionally, the New England grocery chain Stop & Shop tested Speedpass at their Boston area stores; the units were removed in early 2005. Speedpass has also been previously available through a Speedpass Car Tag and a Speedpass-enabled Timex watch.
Document 13: Breeze Card: The Breeze Card is a stored value smart card that passengers use as part of an automated fare collection system which the Metropolitan Atlanta Rapid Transit Authority (MARTA) introduced to the general public in early October 2006. The card automatically debits the cost of the passenger’s ride when placed on or near the Breeze Target at the fare gate. Transit riders are able to add value or time-based passes to the card at Breeze Vending Machines (BVM) located at all MARTA stations. The major phases of MARTA's Breeze transformation took place before July 1, 2007 when customers were still able to purchase TransCards from ridestores or their employers. They were also able to obtain paper transfers from bus drivers to access the train. As of July 1, 2007 the TransCard and the paper transfers were discontinued and patrons now use a Breeze Card or ticket to access the system (except for single bus rides, which can still be paid for in exact change), and all transfers are loaded on the card. Breeze Vending Machines (BVM) distribute regional transit provider passes (providing that the requested system has completed their transformation to the Universal Breeze AFC.) The Breeze Card employs passive RFID technology currently in use in many transit systems around the world.
Document 14: EZ-Link: The EZ-Link card is a contactless smart card based on the Sony FeliCa smart card technology and used for the payment of public transportation fares in Singapore, with limited use in the small payments retail sector.

It had a monopoly on public transportation fare payments in Singapore until September 2009, when the NETS FlashPay card, which had a monopoly over Electronic Road Pricing (ERP) toll payments, entered the market for transportation payments (and vice versa). EZ-Link cards are sold, distributed and managed by EZ-Link Pte. Ltd., a subsidiary of Singapore's Land Transport Authority. In September 2009, the new CEPAS EZ-Link card replaced the original EZ-Link card.
