You discover it at boarding: your 15-year-old is heading to an exchange program in the US and no bank back home has a card for them. Paths exist, but no one explains them properly. Wise multi-user solves it with real parental control and low spread. C6 Conta Jovem works for a teen traveling with family. A prepaid card from an FX bureau is almost always the worst option — and the one that sells most at agencies. This guide gives you the right choice for each scenario, with limits, risks, and what to do when the card gets lost at 10 PM in Lisbon.

The question always lands the last week before departure. "My 14-year-old is going to Disney with school, what card do I give them?". Or worse: "My 17-year-old's exchange to Boston was approved, she boards in 20 days, the bank here said she can't have an international card. Now what?".
Now what is this: Brazil doesn't have a native product like the US PiggyKid or Greenlight cards for minors. Itaú, Bradesco, Santander, Nubank — none of them sell a prepaid international card for under-18s with parental controls and a decent spread. The local market for minor cards stopped at the teen checking account for kids who get an allowance. If your child is traveling, you'll have to improvise.
The good news: you can improvise well. Wise has a multi-user product with dependents from age 13. Nomad issues a supplementary card linked to the titleholder's account. C6 has a Conta Jovem that works in some scenarios. And for young kids (6-12), the problem simply doesn't exist — parents centralize everything on their own international cards.
The bad news: most parents fall for the FX bureau marketing. They buy a Travel Money prepaid card at the airport, pay R$ 6.30 per dollar when the official rate is R$ 5.55 (nearly 14% spread), and still think they're financially protecting their kid. They're just burning money.
This guide separates what works from what looks like it works, organized by real scenario.
The structural problem: why no native product exists
International cards for minors in Brazil hit three regulatory walls:
- Minor law: under-18s cannot have their own credit card without explicit judicial authorization in some cases. A functional international prepaid card is viable but requires a guardian.
- FX (BCB Resolution 277): FX operations for minors require documented legal guardians. Banks prefer not to issue separate products — it costs more than it's worth.
- AML compliance: a minor with an independent international card is a compliance flag. Brazilian banks avoid it.
Result: international fintechs (Wise) or those that pivoted to USD (Nomad) filled the void. And C6, the only Brazilian bank with a dedicated teen product, did it without being exactly international — it's a domestic account that pays in dollars with an embedded spread.
The four paths available as of May/26
| Product | Min age | Card type | Parental control | Spread over interbank FX | Typical daily limit | When it makes sense |
|---|---|---|---|---|---|---|
| Wise multi-user | 13 (dependent) | Physical, dependent's own | High: limits, categories, remote block | 0.4-0.7% | Configurable up to $5,000 | Exchange, teen alone, family travel |
| Nomad supplementary | No formal minimum (supervised use) | Add-on linked to holder | Medium: monthly limit, block | 1.1-1.4% | Up to main account limit | Family already using Nomad, travel with kid |
| C6 Conta Jovem | 13-17 | Brazilian debit with international function | High: parental app controls everything | 2-3% over PTAX + full IOF | $1,000-2,000 (adjustable) | Teen on short trip with family |
| FX bureau prepaid (Travel Money, Confidence) | None (supervised use) | Reloadable card | Low: only per-load limit | 7-10% | Loaded amount | Small backup, emergency |
Straight up: for 80% of cases, Wise multi-user is the right choice. For the other 20%, one of the alternatives. FX bureau prepaid almost never.
Scenario 1 — Kids 6 to 12 traveling with parents
Recommendation: no card needed for the kid.
This is the easiest scenario. Parents already have (or should have) Wise, Nomad or a premium Brazilian card with reduced FX fees. Everything goes through them. The child doesn't carry a card, doesn't have an app, has no financial responsibility.
The common mistake is parents buying an FX bureau prepaid "in case the kid needs it". The kid won't need it. If separated from parents, it's a safety problem, not a money problem — and a card in an 8-year-old's hands is more risk than solution.
Correct setup:
- Parents with Wise or Nomad as main travel account
- $100-200 cash split between the two adults
- Photo of the child's passport on both parents' phones
- Bracelet or card with name + parents' phone numbers (not money)
Card cost for the kid in this scenario: zero. It's the ideal scenario.
Scenario 2 — Teen 13 to 17 on international exchange
Recommendation: Wise multi-user is the gold standard.
This is the most common scenario today. School exchange to the US, Canada or Ireland, 3 months to 1 year. The teen will live abroad, will need to pay for Uber, buy food, eventually rent things. They can't depend on the parents' card for two reasons: time zone (parent in São Paulo asleep at 3 AM when child needs them in Boston) and financial responsibility (controlled limit, not full account access).
Recommended setup:
Before boarding (2 weeks):
- Parent opens Wise account (if not already).
- Adds child as dependent. Wise requires minor's documents + guardian authorization. Process takes 3-5 business days.
- Orders physical Wise card for the child. Delivery in 7-10 days.
- Initial load: 1 month of expected allowance + emergency reserve (~$500-800 extra).
- Configures in parents' app:
- Daily limit ($100-200 depending on city)
- Risk category blocks (gambling, adult sites, crypto)
- Push notification on every transaction
- Remote block ready to trigger
After arriving in the US (first 2 weeks): 6. Open a US debit account. Charles Schwab High Yield Investor Checking accepts foreigners with a temporary local address (school/host family), charges no annual fee, and refunds ALL global ATM withdrawal fees. It's the dream account for an exchange student. 7. Child uses Schwab for day-to-day USD spending, Wise becomes reserve and bridge with home.
Why this works better than anything else:
- Wise has 0.5% spread — over 1 year of exchange, that's $300-500 saved vs Nomad
- Real parental control: see spending in real time, adjust limit remotely
- Child's own physical card — doesn't look like "mom's card", accepted everywhere
- If lost, block in 10 seconds via parents' app. Wise reships in 5-10 business days (ask at embassy/school, not at temporary address).
Alternative when Wise doesn't fit: C6 Conta Jovem with Mastercard. Works internationally, but the 2-3% spread + full IOF makes it 4-5x more expensive than Wise long term. Only worth it if the family is already a heavy C6 customer and wants to keep everything in one place.
Scenario 3 — Teen 14 to 17 traveling with family
Recommendation: depends on the autonomy level you want to give.
15-30 day trip, family together the whole time. The teen will want to buy sneakers alone at the mall, pay for a snack with friends they met at the hotel, go out to the movies. Parents want controlled autonomy.
Two viable choices:
Option A — Wise multi-user with own card:
- Child has physical card
- Parents load $50-100/day of "travel allowance"
- When child spends it, they ask for more — parents transfer in 5 seconds via app
- Hard cap daily limit configured
Option B — Nomad supplementary card:
- No physical card of their own for the child (Nomad issues supplementary but use is supervised)
- Parents hand the supplementary when the child goes out
- Control: shared monthly limit, instant block via app
- Simpler, less "teen product" feel — works like "I'm lending you my extra card"
For family trips up to 30 days, Option B (Nomad) is usually enough and simpler. For long trips, exchange or families with 2+ teens, Option A (Wise) scales better.
Scenario 4 — Young adult 18+
No special rule. Their own Wise or Nomad, independent account, no guardian. This scenario isn't this guide's problem.

Parental control: what each platform actually delivers
Marketed vs delivered:
| Feature | Wise multi-user | Nomad supplementary | C6 Conta Jovem | FX bureau prepaid |
|---|---|---|---|---|
| Daily limit | Yes, granular | Monthly only | Yes | Only per-load limit |
| Instant remote block | Yes | Yes | Yes | Slow (call center) |
| Category block (gambling, adult) | Yes | Partial | No | No |
| Push notification per transaction | Yes | Yes | Yes | Not all |
| Transaction geolocation | Yes | Yes | Yes | No |
| ATM withdrawal abroad | Yes, Wise fee (~$1.50) | Yes, ~$2.50/withdrawal | Limited | Expensive |
| Lost card reshipment | 5-10 business days, international | 7-15 business days | Brazil only (no international reship) | Slow |
Wise wins on every line that matters. Nomad is a comfortable second. C6 works, but Brazil-only reshipment is a serious travel problem.
Real risks and what to do
Teen loses card at night abroad.
- Wise/Nomad: 10s block via app. Child uses Wise virtual on phone (Apple Pay / Google Pay) until physical arrives. Reship: 5-10 business days.
- C6: block via app, but reship Brazil-only. Child stays without card until returning.
- FX bureau prepaid: block via phone center, slow process, refund depends on police.
Universal solution: always have physical card + virtual card on phone (Apple Pay / Google Pay). If physical is lost, virtual keeps working.
Teen becomes victim of online scam.
- Wise: fraud protection for unrecognized transactions, reasonable chargeback process (15-30 days).
- Nomad: limited protection, depends on card partner (Mastercard international).
- C6: bank protection, but for international transactions the process is slower.
Teen exceeds limit.
- All products have hard cap on loaded limit. Can't spend more than what's available. This is the structural safety — that's why these accounts beat parents' credit cards.
Teen withdraws too much at ATM.
- Wise: $1.50 + 2% above $100/month withdrawal. Configurable.
- Nomad: ~$2.50 per withdrawal. Recommend larger, less frequent withdrawals.
- C6 Conta Jovem: expensive international withdrawal, avoid.
Recommended practical path by profile
Family with young child (up to 12) traveling:
- Parents with Wise/Nomad as main account
- Brazilian premium card as backup with reduced FX fee
- $200 cash split
- Total parent cost: zero additional product for the child
Teen (13-17) traveling with family:
- Wise multi-user (if international travel is frequent) OR
- Nomad supplementary (if family already uses Nomad and trip is one-off)
- Cost: zero annual fee on both, only FX spread
Teen (13-17) on exchange:
- Wise multi-user before boarding
- Charles Schwab High Yield Checking after arrival (3-6 weeks)
- $300 emergency cash
- WhatsApp + emergency call set up
- Cost: ~$10 Wise card + zero Schwab. Spread 0.5%.
Young adult (18+):
- Own Wise or Nomad
- Brazilian premium card with reduced FX as backup
- Outside this guide's scope
The $400 mistake parents make every week
A parent buys Travel Money at the airport, loads $2,000 for a child going 4 months to Ireland. 8% spread over the commercial dollar. The parent paid $160 extra just on spread. In 4 months, the child withdraws 3 more times at ATM ($10 each fee), loses the card and reshipment takes 20 days. Total burned on the wrong product: ~$300-400.
The same operation on Wise multi-user, with child's own card, parental control and 0.5% spread: total cost ~$10 + $10 spread.
Difference: $300-400 per exchange. Per child. Every time.
Documentation you need
Before opening Wise multi-user for a dependent:
- Parents' ID (titleholder)
- Minor's ID (from age 12 usually exists)
- Minor's tax ID
- Proof of address (either parent)
- Guardian selfie for biometrics
- Electronic authorization in app (Wise generates the form)
For Nomad supplementary:
- Guardian's active Nomad account
- Dependent's documents (ID/tax ID)
- App request, approval 24-48h
For C6 Conta Jovem:
- Minor's ID and tax ID
- Both guardians' authorization (if applicable)
- Supervised use agreement
About FX and taxes
Wise and Nomad operate as international remittance. Brazilian IOF of 1.1% applies on each USD balance load (until the schedule drops soon — see IOF guide). C6 Conta Jovem operates as international debit, full IOF of 3.5% per transaction for now.
In 2026, with remittance IOF gradually dropping, Wise and Nomad become even more advantageous vs Brazilian debit. The difference goes from today's 2-3% to 4-5% by year-end. Anyone planning exchange for 2027 should set up the Wise structure now.
For more on IOF and the drop schedule, see the cluster-specific guide. To understand why Wise became the standard for Brazilian international travel, see the Wise vs Nomad vs Avenue comparison guide.
Honest conclusion
Brazil isn't launching a native product for traveling minors anytime soon. The market is small, compliance is expensive, and margin is low. The solution will keep being the international fintech for the next 2-3 years minimum.
Parents who understand this early save money and headaches. Parents who find out at the airport will pay dearly — either by buying the wrong prepaid, or improvising with their own card and discovering unauthorized international charges three months later.
For 80% of families, the answer is Wise multi-user. Set it up once, it serves the entire international life of the child until they become an adult. ~$10 initial investment, real control, low spread. No Brazilian product comes close today.
Pontos-chave
No native Brazilian product for international kid or teen cards exists. The market solves it via workaround.
Wise multi-user (dependent from age 13) is the best option for a teen on exchange or traveling alone. Real parental controls, low spread, dedicated app.
Nomad supplementary card works for families already using Nomad. Single account, category controls, no independent card for under-18.
