Cardzen

Cardzen とは？

The average premium cardholder leaves up to $1,500 in credits and points on the table every year. Cardzen tracks every credit, perk, and multiplier across your cards, reminds you before anything expires, and tells you which card to use for every purchase. Ask the AI advisor anything about your wallet, get a daily digest of what needs attention, and stop paying annual fees for benefits you never use.
