SUBE cards are credit card sized cards that allow you to preload payment and board public transportation in Buenos Aires, greater Buenos Aires other cities in Argentina such as Rosario, Mendoza and Bariloche without the need for a paper ticket.
SUBE works not just for the subte (subway) but also for colectivos (buses), trenes (trains), and some ferries in Buenos Aires and other cities.
It should be noted that as of late 2024, subte stations now accept direct credit or debit card payments, so travelers don’t strictly need a SUBE card if they only use the subway occasionally.
For buses and trains, SUBE is still the standard, so having one makes day-to-day travel smoother.
Those who register their cards with the government to track aggregated user patterns and tax dodgers, pay only 45% of the full fare.
Students, retirees, and low-income groups can get further subsidies.
Whether privacy is worth the higher fare is a personal decision but one subway worker in Catedral station said a surprising number of people — almost half — dont’ register their cards.
The tracking is part of Buenos Aires’ efforts to operate as a smart city.
This tracking helps city planners analyze traffic flow, optimize bus and subway routes, and understand peak travel patterns — so it doubles as a tool for urban planning.
In sum, if you don’t care about privacy, you pay less.
