For a short visit with no planned eligible transfers, an enabled foreign contactless Visa or Mastercard can be the simplest way to pay on supported transit services. If you expect eligible connections in Greater Buenos Aires (AMBA), need a SUBE-specific benefit, or want the broader established transit network, use a physical or supported digital SUBE instead. Coverage is not universal for bank-card payments, so check your route and carry a backup.
How the two payment options differ
Argentina accepts contactless Visa and Mastercard credit, debit, and prepaid cards issued abroad on services equipped for open payment. The official terms also describe NFC phones or watches and QR as payment options, but acceptance depends on the service and active equipment. A bank card that works on one vehicle or line is not proof that it will work across your trip. See the official open-payment information.

SUBE is the broader established network option. The official SUBE FAQ lists buses, subways, trains, metrobuses, trolleybuses, and boats across 61 localities. Open-loop bank-card payment, by contrast, is available only where the relevant equipment is active. Check the SUBE FAQ.

RED SUBE can reduce the cost of eligible AMBA connections, but it applies only when you pay with physical or digital SUBE—not with a contactless bank card. On eligible combinations, the first trip is charged at full fare, the second gets 50% off, and later eligible trips get 75% off within the program’s two-hour window. Exclusions apply, and you must use the same eligible payment medium for the linked journeys. Read the RED SUBE rules.
#1 Best Overall
- SECURE YOUR WALLET FROM e-PICKPOCKETING: Prevent potential identity and financial theft through your contactless cards. This is the simplest and most effective prevention solution! Block RFID and NFC signals, protect your personal information, and enjoy peace of mind wherever your travels or business take you.
- JAMMING CHIP: An antenna and jamming chip makes up the main components of the card. The antenna will sense incoming radio waves and draw power for the chip to create a jamming signal. Lifetime usage as the card does not require battery.
- BROAD WORKING DISTANCE: With a 2.4” working distance, your entire wallet stays protected. The premium RFID blocking card helps secure cards within 1.2” on either side, providing reliable protection against electronic pickpocketing.
- ULTRA-THIN & COMPACT: At the size of a standard credit card and at only 0.03” thick, the card will fit into any wallet, purse or card case. Keep your wallet compact with no added bulk from this card. Best for travel, business, and everyday use.
- TEST THE CARD: Test the card is working at your local supermarket. At the self-service checkout machines, combine the card and a contactless card on the payment reader. Payment with the contactless card will be blocked and an error message should occur on the reader.
That makes the choice practical: if you expect qualifying connections during the two-hour window, SUBE may be worth the extra setup. If you expect only isolated rides, or your route does not qualify, the discount may not change your decision.

Choose based on your trip
Use a contactless bank card for a simple, supported ride
If you are taking a small number of rides and do not expect eligible AMBA transfers, trying an enabled foreign contactless Visa or Mastercard can avoid obtaining a separate transit card. Confirm open-payment support for the specific service, and keep another payment option available in case the route or card is not accepted.

Check before relying on one payment method
- Confirm open-payment support for the exact line, vehicle, or mode on your planned route.
- Ask your card issuer about foreign-transaction charges, restrictions, and approval when used abroad.
- Do not assume that a digital wallet token will behave exactly like the physical card; acceptance rules do not settle behavior for every issuer and wallet.
- Check current SUBE purchase and loading details through official channels, since prices and terms can change.
- Keep a backup payment option available rather than relying on one card for every leg.
