Per-seat pricing is what usually forces the comparison
Most people arrive at a Blinq alternatives search for one of two reasons, and it is worth separating them because they lead to different answers.
The first is cost at scale. Per-user pricing is clean and predictable at twenty seats and becomes the dominant line item at two thousand. When the card programme is company-wide rather than sales-only, the seat count is headcount, and the annual number stops looking like a marketing tool and starts looking like a platform commitment. Pricing by active codes rather than by seat changes that arithmetic, though the honest caveat is that it changes it in your favour only if your card count is genuinely lower than your headcount.
The second is a failed IT review. SSO alone is frequently not enough — the question that stops rollouts is deprovisioning, and "an admin deletes the card" is not an acceptable answer when the control needs to be automatic. That is a capability question rather than a pricing one, and no amount of discount resolves it.
What Blinq does better
Blinq's free plan is the most generous in the category and it is not close. If you are one person who wants a good digital card at no cost, Blinq is the right answer and recommending anything else would be dishonest.
Its native mobile apps are also more refined than a web-first experience, which matters if the primary interaction is opening your own card on your phone to show someone. QRBold's cards are web pages — nothing to install for either party, which is an advantage for the person scanning and a trade-off for the person sharing.
