EURO CARD WALLET – 10€ Always On You

EURO CARD WALLET – 10€ Always On You

(Credit Card Size Coin Holder)

This is not a coin wallet.

It’s an emergency backup cash card that lives in your wallet.

Same exact size as a credit card, but with 10€ always available when:

• the POS is down
• your phone battery is dead
• cash only is accepted
• you need to pay fast, right now

You put it in your wallet once.

You forget about it.

But when you need it… it’s there.

No noise.

No mechanisms.

No bulk.

Just real cash, always available, without carrying loose coins.

⭐ WHY IT’S A REAL BACKUP

• ISO 7810-ID1 format (same as a bank card)

• Total capacity: 10€

   

  • 4× €2 coins
  • 2× €1 coins

   

• Ultra-thin and lightweight
• Slides behind your cards in the wallet
• Zero moving parts → nothing to break
• Designed for EDC, travel, motorcycle, car, sports

This is the kind of item you almost never use…

but when you do, you’re glad you have it.
