Cardpool's advantage was a seamless, balance-verified exchange that removed the trust barrier from peer-to-peer gift card trading.
Features such as instant redemption, snail-mail-free electronic selling, and the Cardpool Purchase Guarantee differentiated it from informal resale channels during its operating years.
Cardpool set buyback and resale prices based on each brand's popularity, earning a cut as the intermediary on every transaction.
Highly desirable cards such as Best Buy traded close to face value, while less popular brands carried steeper discounts, letting the platform balance supply and demand across card types.
Cardpool's core offering was an online gift card exchange where consumers sold unwanted gift cards for cash and bought pre-owned cards at a discount.
The marketplace verified each card's balance before listing, accepted both physical cards mailed in and electronic codes, and added instant-delivery options plus a mobile app for redeeming cards on the go.
