What a Prepaid Card for Kids Actually Is

A prepaid card works differently from a real debit card tied to a bank account: it has to be loaded with money before it can be spent. Because of that one mechanic, the card can't go negative — the loaded balance is a hard limit, not a suggestion. That's exactly why it's usually the first card a child gets, years before most banks will open a real account in their name.

Why Age Requirements Vary So Much

Most banks require someone to be at least 13 for a joint checking account and debit card, and legally an adult to open one alone. Prepaid cards sidestep that entirely: some accept kids as young as 5 or 6 (BusyKid, Acorns Early), and a few — Greenlight, FamZoo, Jassby, Mazoola — have no minimum age at all, since the card is really tied to the parent's account and controls, not the child's own credit history.

Comparing the Top Prepaid Cards

  • Greenlight — starts at $5.99/month for up to 5 kids, with tiers up to $19.98/month (Family Shield) adding identity protection and investing; debit limit around $5,000, ATM limit $400.
  • Acorns Early (formerly GoHenry) — $8 or $12/month for up to 4 children, built around educational games and chores; debit limit $2,500, ATM limit $120.
  • Chase First Banking — $0/month, ages 6-17, but only works if the parent already has a Chase checking account to fund it from; debit limit $400/day, ATM $100.
  • FamZoo — $5.99/month plus a $4.95 cash deposit fee, with a genuinely unusual feature: parents can set up "informal loans" to a child at whatever interest rate they choose.
  • BusyKid — $4/month billed annually at $48, covers up to five kids on one subscription, and includes a basic investment account.
  • Current — no monthly or annual fee, automatic round-ups that push spare change into savings, and access to 40,000+ fee-free ATMs, but only for teens 13+.
  • American Express Serve — $0 to $7.95/month depending on the version, one of the few offering 1% cash back, but requires the cardholder to be 18.
  • Jassby and Mazoola — no minimum age, no physical bank account required; Jassby leans into a rewards catalog (Apple, Starbucks, Target gift cards), Mazoola is virtual-card-only and markets itself specifically as COPPA-compliant.

What Actually Matters When Choosing One

Look Past the Monthly Fee

$0/month sounds best on paper, but a free card that only works if the parent already banks with that institution, or a $5.99 card that covers five children on one subscription, can both be cheaper in practice than they look on a comparison table. AbacusWise breaks down the free options — and when they actually beat a paid card — in its guide to free debit cards for kids.

Match the Spending Limits to Real Use

A $400 daily debit limit is plenty for a 9-year-old's allowance and school purchases, but becomes a problem the day that same card is also meant to cover a family shopping trip.

Practical example: for a family with three kids ages 7, 10, and 13, a single BusyKid or Greenlight subscription covering all three at $4–$19.98/month usually beats paying for three separate app-based accounts, simply because most of these tools price per family, not per card.

Pros and Cons of Prepaid Cards for Kids

Pros:

  • Can't go into debt — the card just declines once the loaded balance runs out, since there's no line of credit behind it
  • Lower age minimums than any real bank account, some with no minimum at all
  • A lost or stolen card can be frozen instantly from the parent's app, unlike cash
  • Gives a child hands-on practice with real money before the stakes are as high as an adult account

Cons:

  • Reloading with cash usually costs $3 to $5 each time, an easy cost to overlook when comparing "$0/month" cards
  • Monthly fees on some prepaid cards are actually higher than a real teen checking account
  • Balances and activity don't build any credit history, even after years of consistent use

Is the plan to keep a child on a prepaid card only until they turn 13, or to actually use these first few years to build real money habits?

Wise Tips

  • Add up the real monthly cost, not just the advertised fee — a family plan covering multiple kids at once is often cheaper than it looks even when the sticker price is higher.
  • Confirm the card is FDIC- or NCUA-insured before loading meaningful amounts, since not every prepaid product carries the same protections as a bank account.
  • Read the privacy policy of any app collecting a child's data — COPPA compliance should be explicitly stated, not assumed.

TL;DR

Prepaid cards for kids remove the two barriers that keep children off a real bank account — age and credit — by requiring the balance to be loaded before it's spent. The right pick comes down to matching spending limits and family pricing to how many kids need a card and how they'll use it, not to picking the lowest sticker price; reload fees and per-family pricing usually matter more than the monthly rate quoted upfront.
