> Is there a better way?

If one's visitors are gamers, perhaps one might use gaming payment providers to sell an "supporter badge"? But that's perhaps be pushing their envelope.

If one's visitors are from the "rapidly-developing world", with well-adopted candybar-scale micropayment systems - China, India, Indonesia, Brasil, Kenya, SK, Sweden... hmm. Direct access from elsewhere seems still very limited, but perhaps one might use a global payment gateway like Adyen? My impression is transaction cost is more than $0.10 but less than $1.

In the "less-rapidly-developing world", X.com has been working towards a similar superapp with Visa for the US. The Visa/MC duopoly seems to have shifted from its years of preventing US micropayments, to something like "maybe 2030-ish".
