Free app allows public run check on taxi drivers - Independent.ie
You can just input the car reg or roof number or driver badge and up pops a photo and name of the driver.
Also the car details come up - color, make and reg.
Walk along the rank, put the number in your phone and if the details don't come up you know it's a rouge driver and you can report.
It's an official app so all the drivers should be on the database.
What other information should the customer be told about their driver - criminal record maybe?
You can do it online also but you don't get a photo of the driver.
