How Do I Test or Use an Audio Jack Reader Such as Shuttle, UniMag, UniPay, or VP3300AJ?

I have an audio jack reader and I want to swipe a card and see the results. What do I do?

The ID TECH audio jack reader is supported as a mobile device accessory on iOS, Android, Windows mobile, and Blackberry platforms. Many application providers have written and distributed applications for these readers. ID TECH provides a demo application to prove reader functionality and compatibility. Make that the audio of your mobile device is turned to the maximum volume.

Download the UniMag Demo or UniMag Utility for Shuttle, UniMag II and UniMag 1.5 from Apple's app store. Launch the app, select the appropriate reader type, and swipe a card.

For VP3300 Audio Jack, download uDemo from the VP3300 AJ product page. 

The Google Play Store has a few apps supporting the Unimag and a Universal SDK Demo app supporting UniPay and other devices.
