View Mobile Device Certification


Certification of Mobile Devices for the Hudson Platform

When the first tablet computers were released to the market, Hudson quickly adapted its applications to run on those specific devices. As tablets and other mobile devices became more popular, the market was suddenly flooded with a variety of devices made in many different sizes and powered by several different operating systems.  It quickly became challenging for Hudson to adapt its code to work on all devices and platforms.

As clients consider integrating mobile devices into their fleets we request that before purchasing devices in any quantity, that you review the list of previously certified hardware and operating systems below. These are devices which we have tested and evaluated and are certifying as HGTS compatible (Hudson Ground Transportation System).  If you are interested in a new device or device not previously certified by Hudson, we invite you to send us a sample piece of hardware. We will test it for certification and add to the list.  If adjustments or updates to our applications are required in order to run on the sample device we will generally make those adjustments at no charge. This process however can add to the time required for full deployment.
Please see important note at the bottom of this page regarding updating the Operating System on your mobile device(s)!.

Evaluation Criteria

The Hudson device certification process is a fairly straight forward instance of installing the application on a device and then observing and measuring its performance. While the application may run, Hudson looks to ensure it runs consistently, predictably and quickly.  If the app runs slowly or at less than optimum levels on a specific device, the device might not be certified, though it would still launch and run. Here is a list of the evaluation steps taken with Android devices.

Device Testing
-  Download Latest Version of app
-  Install App (This may require allowing unknown sources)

Credit Card Swiper / Reader Compatibility

If you will be accepting and swiping credit cards in the field, then you will need to add an external credit card reader to your VMDT hardware.  There are many different devices out and available on the market, but like the VMDT hardware certification above, Hudson has reviewed and evaluated the card readers below and found them to be compatible with all approved VMDT hardware.:

Most devices on the market currently use either iOS developed by Apple, or Android developed by Google.  These developers offer updates to the operating systems frequently.  It is vital that you do not update the operating system on your device until you have confirmed with Hudson that the vMDT application is not adversely effected by the update!  While many clients like to stay on top of the latest updates to hardware operating systems, in this case, upgrading your devices can result in unexpected problems with the way the device works.  You can check back to this web page at any time to see if new OS versions have been reviewed, tested and certified.  In all situations, be sure you backup your device BEFORE doing an OS update. Failure to do so may result in the inablility to revert to an earlier Operating System.
