The UniMag family of audio jack readers communicate with the host device (phone or tablet) via the audio jack. The way this works is similar to a fax machine. In that, the card is read and the character stream is converted to an audio signal and is is sent to the phone or tablet via the audio jack. An application written using ID TECH's audio jack SDK will "listen" to the audio and convert it back to characters by decoding the audio signal.
Virtually all Apple devices (iPhones, iPads) are compatible and should work without any additional configuration. Just make sure the audio is clear and unaltered. Turn the volume up (80 - 100%). Make sure it is set to stereo not mono. No equalizer, no base-boost, no effects.
There is a umcfg.xml file. This file holds a set of settings (setting profile) that have been found to work for each device we by model number. We have either tested the device ourselves or some from customers who report that they have a customer discovered the settings profile that work of a specific model device.works and share it with us.
