We want to accept credit card postings via iPhone and Android phones, but cannot find any devices that connect via the headphone jack that fills the field in the phone’s browser. This is very easy to do with USB devices connected to a PC.
There are several existing devices for telephone jacks with a proprietary API, but from what I can say, they require their own applications. To do this, it makes sense to standardize this or use the open source API, but perhaps there is no market yet.
Does anyone know how to get a credit card swinger for headphones to fill in the field in the phone browser?
EDIT: This is not possible. For some reason, no one has a problem using HID standard USB readers for PC / Mac, but this is not normal for phones and tablets. Thus, the best option is to use PhoneGap to connect to an inexpensive reader.
But here is the problem: the readers' choice seems to be between 50-100 US dollars or 5 US dollars from China, which we cannot work reliably. I am looking for a reliable device in the range of $ 15 to $ 20 and will post my research as reliable answers.
