Q) Should I feel guilty for using libdmtx if I never make a donation?

Absolutely not. You should never feel guilty about using libdmtx. It is 100% free software, which in this case guarantees:

• freedom to use
• freedom to modify
• freedom to redistribute
• free of cost
• free of guilt

Q) In that case, why would anyone ever make a donation?

Donations come in many forms including source code, bug reports, sample images, and yes, cash. People have been extremely generous with their time and effort, and libdmtx is undoubtedly better as a result. Money donations, however, allow individuals and companies to help cover the expenses associated with software development and project hosting.

Q) What kind of expenses could an open source project possibly face?

It's usually a case of small expenses adding up over time, for example:

• New server that uses a tiny amount of electricity
• Website bandwidth
• Research materials (ISO Specification, error correction book, etc...)
• Organizational maintenance fees (legal, accounting, etc...)

Q) Can I donate with my non-US Currency?

Donation amounts should be specified in whole U.S. dollars. The Universal Currency Converter from www.xe.com can help with the conversion.

Q) What is the minimum non-zero money donation?

No minimum.

Q) Why does the donation go to Dragonfly Logic instead of an individual?

We created the Dragonfly Logic, Inc. corporation for two main reasons: for liability protection and to enable formal business relationships. In late 2006 we learned that even "patent free" technologies can be impacted by patents trolls, and this drove home the need for a legal entity to be the official project steward for libdmtx. Copyrights on the code, images, and documentation are still held by individuals, but the corporation handles all financial transactions.

Q) Is this a tax deductible donation in the U.S.?

We are structured as a for-profit corporation, so donations from individuals probably are not tax deductible.
