Oobit picks a fundamentally different architecture from every other card in this comparison set: funds stay in your wallet, and each swipe triggers an on-the-fly swap and settlement. It's technically elegant and the self-custody story is real. The practical trade-offs are low unverified caps, KYC-gated mobile-wallet support, and the per-spend fee model.

Where Oobit is strong
- Self-custody. Funds never leave your wallet. For users who internalised "not your keys, not your coins", this is the only correct architecture.
- No top-up step. No pre-funding means no minimum amount sitting on the card.
- Wide global acceptance. 150+ countries supported.
Where Cryptocardium is stronger
- Higher unverified ceiling. Cryptocardium's no-KYC tier scales to $50k per top-up; Oobit's unverified tier is small-spend only.
- Apple Pay without KYC. Oobit asks for ID before mobile-wallet provisioning.
- Lower effective fees at scale. 2% once at top-up vs 1.5-3% on every spend.
- Monero. Oobit doesn't do XMR.
- Programmatic access. REST + MCP for agents.
Which should you choose?
Oobit is the right answer for users whose primary value is self-custody and who accept the low unverified caps. Cryptocardium is the right answer for everyone else — higher caps, no KYC at scale, no per-spend fee, mobile wallet on the unverified tier, and an API.
