We have an app called VeriScan Pro, it scans IDs (such as Driver License) on iPad and allows picture taking, data / signature collection. All data is saved to .csv file you open in Excel. Signature gets a time/date stamp. We will be glad to provide few free Licenses for qualified parties in exchange for a feedback.
