Question: Does the OPUS card use close physical proximity or WiFi networks to make payments?

full_context: Document 1: OPUS card: OPUS is a rechargeable, contactless stored-value smart card using the Calypso Standard and is used by major public transit operators in Greater Montreal and Quebec City, Quebec, Canada.
Document 2: ORCA card: The ORCA ("One Regional Card for All") card is a contactless, stored value smart card used for payment of public transport fares in the Puget Sound region of Washington state, United States. ORCA was introduced on a limited basis on April 20, 2009, with a full public launch in June 2009. As of March 2016, an adult ORCA card costs $5, one of the highest prices for a public transportation smart card in the United States.
Document 3: Octopus card: The Octopus card () is a reusable contactless stored value smart card for making electronic payments in online or offline systems in Hong Kong. Launched in September 1997 to collect fares for the territory's mass transit system, the Octopus card system is the second contactless smart card system in the world, after the Korean Upass, and has since grown into a widely used payment system for all public transport in Hong Kong, leading to the development of Oyster Card in London.
Document 4: List of smart cards: Some widely used contactless smart cards include Sydney's Opal Card, London's Oyster card, Hong Kong's Octopus card, Stockholm's Access card, Japan's Suica and Pasmo cards, Manila's Beep cards, ETC Card], Paris' Calypso/Navigo, the Dutch OV-Chipkaart, Toronto's Presto card and Lisbon's LisboaViva card, which predate the ISO/IEC 14443 standard. The following tables list smart cards used for public transport and other electronic purse applications.
Document 5: Yikatong: The Beijing Municipal Administration & Communication Card (), more commonly known as the Yikatong (literally One-card pass), is a store-value contactless smart card used in Beijing, China, for public transportation and related uses. It is similar to Hong Kong's Octopus card, Singapore's CEPAS, or the Oyster Card used by Transport for London in London, England.
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 7: Proximity card: A proximity card or prox card is a "contactless" smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and "contact" type smart cards. The Proximity cards are part of the contactless card technologies. Held near an electronic reader for a moment they enable the identification of an encoded number. The reader usually produces a beep or other sound to indicate the card has been read. Proximity cards typically have a read range up to 50 cm (< 15 inches) which is the main difference with contactless smartcard with 2 to 10 cm (1 to 3 inches) . The card can often be left in a wallet or purse , and read by simply holding the wallet or purse near the reader. The term "proximity card" refers to the older 125 kHz devices as distinct to the newer 13.56 MHz contactless smartcards. Second generation prox cards works in UHF frequency are in use for mass and distance reading application.
Document 8: Digital wallet: A digital wallet refers to an electronic device that allows an individual to make electronic transactions. This can include purchasing items on-line with a computer or using a smartphone to purchase something at a store. An individual's bank account can also be linked to the digital wallet. They might also have their driver’s license, health card, loyalty card(s) and other ID documents stored on the phone. The credentials can be passed to a merchant’s terminal wirelessly via near field communication (NFC). Increasingly, digital wallets are being made not just for basic financial transactions but to also authenticate the holder's credentials. For example, a digital wallet could verify the age of the buyer to the store while purchasing alcohol. The system has already gained popularity in Japan, where digital wallets are known as "wallet mobiles". A cryptocurrency wallet is a digital wallet where private keys are stored for cryptocurrencies like bitcoin.
Document 9: FeliCa: FeliCa is a contactless RFID smart card system from Sony in Japan, primarily used in electronic money cards. The name stands for "Felicity Card". First utilized in the Octopus card system in Hong Kong, the technology is used in a variety of cards also in countries such as Singapore, Japan and the United States.
Document 10: Contactless smart card: A contactless smart card is a contactless 13.56-MHz credential whose dimensions are credit-card size. Its embedded integrated circuits can store and sometimes process data and communicate with a terminal via radio waves. There are two broad categories of contactless smart cards. Memory cards contain non-volatile memory storage components, and perhaps some specific security logic. Contactless smart cards do contain read-only RFID called CSN (Card Serial Number) or UID, and a re-writeable smart card microchip that can be transcribed via radio waves.
Document 11: Rabbit Card: The Rabbit Card is a rechargeable contact-less stored value smart card used to transfer electronic payments in systems in Thailand. It was launched in May 2012 to collect fares for the BTS Skytrain and the Bangkok BRT. The card can be recharged at minimum THB100 at a time. It can be recharged at all BTS and BRT ticket offices and most of McDonald's branches in Thailand.
Document 12: Metrebus Card: The Metrebus Card is a contactless smartcard ticketing system for Rome. It has stored value on a paper ticket for either 1, 3 or 7 days. All three versions of the tickets look the same on the front, but on the back of the ticket the magnetic data printed on the ticket varies depending on which version of the ticket was purchased.
Document 13: Microsoft Wallet: Microsoft Wallet is a mobile payment and digital wallet service by Microsoft that lets users make payments and store loyalty cards on certain devices. Making payments is currently supported with the Microsoft Lumia 950, Lumia 950 XL, and Lumia 650. Microsoft Wallet does not require Microsoft Wallet-specific contactless payment terminals, and can work with existing contactless terminals. Similar to Android Pay, Microsoft Wallet utilizes Host card emulation (HCE) for making in-store payments.
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. Established in 2001, it was promoted as the means for speedier boarding times on buses. 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.
Document 15: Android Pay: Android Pay is a digital wallet platform developed by Google to power in-app and tap-to-pay purchases on mobile devices, enabling users to make payments with Android phones, tablets or watches. Android Pay uses near field communication (NFC) to transmit card information facilitating funds transfer to the retailer. It replaces the credit or debit card chip and PIN or magnetic stripe transaction at point-of-sale terminals by allowing the user to upload these in the Android Pay wallet. It is similar to contactless payments already used in many countries, with the addition of two-factor authentication. The service lets Android devices wirelessly communicate with point of sale systems using a near field communication (NFC) antenna, host-based card emulation (HCE), and Android's security.
