Just wanted to put it that there for anyone interested in using a physical reader/swiper to capture credit card data (name, number, expiration), I just finished writing the first reliable plugin for both Android and iOS!
Unfortunately, it won’t work with just any card reader. Only the IDTech Unimag Swipers (original, pro, II, and shuttle) are supported. However unlike the other half-finished or undocumented IDTech plugins floating around, this one actually works and is easy to use.
Hope it helps you!
