Crypto card fees on Onboard Flex Card, and what it offers
Three fields decide what Onboard Flex Card costs: the annual fee, the issuance fee and the top-up fee. For this card the dataset holds an annual fee of Free, an issuance fee of Free and a top-up fee of Not supplied. Top-up is the one that recurs, because it is charged each time value is moved onto the card, which is why it costs more over a year than the annual fee usually does. Onboard Flex Card publishes no ATM limit, so the dash in that column means the dataset holds no value for it rather than that there is no limit.

|---|---|---|---|---|---|---|---|---|---|
| Visa | Virtual | Required | Free | Free | — | 0% | — | Apple Pay, Google Pay | No |
