CardWarden instantly syncs barcodes across your household.
The moment a card's balance changes on one phone, it updates on everyone else's - no refreshing, no double-spending, no awkward surprises at the register.
Check your balance using the retailer's own balance checker, right inside CardWarden.
CardWarden is built on zero-knowledge encryption. Because your card details are encrypted on your device before they're ever uploaded, a breach on our end would expose only unreadable ciphertext - never your card numbers, PINs, notes, or the keys to decrypt them.
