Donor Zip helps solve electronic fundraising for nonprofit organizations in the 21st century. The project is built so that it can be accessed by any non-profit organization, endowment fund or similar, regardless of their area of assistance or the end beneficiary (disabled people, disease research, etc.). It is an application add-on for e-shops that has never been released and run in the Czech Republic before. The principle is very simple. At the end of your online purchase, you can choose to support an organization of your choosing, in any amount, without having to give the organization your contact details.
