The Troika card is now entirely produced in Zelenograd, a significant achievement in domestic production. Deputy Mayor Maxim Liksutov announced that from the end of 2023, both the card and its microchip will be entirely produced in Moscow. More than 3.5 million of these domestically produced cards have already been delivered to the Moscow Metro.

Five-step production process
The Troika card is produced using a complex five-stage technology:
Microchip production – microchips are manufactured on silicon wafers in a specialized “clean” room. The newest Troika chip is entirely domestically produced.
COB module production – the Chip on Board (COB) module protects the microchip from damage. To do this, it is necessary to separate the chip from the plate, install it on the substrate and enclose it in a protective case.
Inlay manufacturing – a film with preliminary marking for future cards is prepared, onto which a COB module with an antenna is soldered, forming a functional RFID tag capable of interacting with turnstiles and validators.
Printing and design of the card – the recognizable design of the Troika card is applied. The insert is placed in plastic, which completes its appearance.
Card personalization – a unique identification number is programmed into the chip memory, which is linked to the Moscow Metro database. This number is used to track the balance, eligibility for travel and other information related to a specific user.
Advanced technology and safety
Each Troika card consists of five layers:
Transparent protective layer Front printed layer Embedded layer with chip and antenna Back printed layer Additional protective transparent layer
The chips themselves are grown on silicon wafers, a process that can take up to three months. The latest Russian-made chip has three times the memory capacity and meets the highest security standards.
The backbone of the Moscow ticket system
Launched in 2013 under the leadership of Mayor Sergei Sobyanin, the Troika card has become the backbone of Moscow’s public transport ticketing system. It efficiently calculates more than 3,500 fare options depending on the type of transport, zone and validity of the pass.
The development of a ticket system based on Russian technologies is a critical step in ensuring the stability and safety of Moscow’s urban transport network, emphasized Maxim Liksutov.
The complete localization of Troika card production underlines Moscow’s aspiration for technological self-sufficiency and uninterrupted service to millions of passengers.”
