A post circulating online this month urges users of the crypto card service BingCard to bring claims against Visa and Mastercard, on the argument that the networks lent their brands to an operation that took deposits and did not return them. The post is anonymous, names no plaintiff, court or case number, and no filed proceeding against either network on these facts could be located. Neither company appears to have been asked to comment. Those claims are reported here as claims, and nothing in this article should be read as a finding that either network has done anything wrong.
What is documented is the customer experience. BingCard is a custodial service: users deposit bitcoin, ether or stablecoins, the value is held off-chain as a card balance, and they spend through virtual or physical cards. Across review platforms the complaints are consistent and repetitive. Withdrawals sitting in a processing state for six weeks and longer. Deposits credited against a balance still showing zero. Pre-authorised amounts that are never released. Trustpilot carries dozens of such reports, and independent scoring sites rate the service poorly.
One detail in that record is worth more than the rhetoric around it. BingCard's own pages now refer to leading international card networks without naming anyone, where earlier material named Visa and Mastercard directly. A company quietly removing the two most recognisable marks in payments from its own marketing is telling you something about the state of its arrangements, and it is a change anyone can check.
The structural point behind all of this is one most consumers have never had explained. A fintech does not join a card network the way a bank does. It sits behind an issuing bank that holds the licence and sponsors a card range, and the network's relationship is with that bank. A logo on a website therefore means a bank somewhere has accepted the programme, not that the network has audited the company, verified its custody arrangements or approved its treatment of customer funds. It is a plumbing connection presented, and widely received, as a certificate of standing.
