System issues | Resolution |
---|---|
Occasional MTN GSM network interruptions | Data is cached if a mobile connection is interrupted or unavailable. Cached data is uploaded to the central server after cellular reconnection is established or via wifi. |
Ease of use | Resolved by Biometrac – software will be further refined given user feedback. |
Device crashing and poor USB connectivity | Biometrac worked with Lumidigm to resolve the driver and USB connectivity issues and facilitate error handling (users no longer have to restart the table upon crash; they can simply disconnect and reconnect the device). |
Matching | A new fingerprinting templating engine was implemented in August of 2013. Matching issues appear resolved, and we will continue to monitor false positive and false negative error rates. |
Prepaid airtime overruns | Moved to postpaid airtime. |
Training issues | Resolution |
Differences in user technological competence | Subsequent training are incorporating local staff – pilot showed this to be effective |
Lack of training among all staff | Additional training and implementation of training-of-trainers model |
