ZankMe makes it easy for musicians to upload music, videos and other digital media and print their own custom download cards, stickers and t-shirt hangers that can be sold or used as promotional giveaways. When fans redeem the cards, artists and labels can capture the fan's email address and location.
Zankme offers a free trial with 10 MB of storage, 50 codes and a 1 month campaign. A basic account is $10/month with 50MB of storage, unlimited codes, and 5 for up to 3 months. A $20 pro account offers 100MB, unlimited codes, and 50 campaigns for up to 12 months.
