*2.2.1 Manual entry*

The VIN is entered by the user using a keyboard from its paper template, from the vehicle registration document, COC2 sheet, etc. Manual entry is still the most common way of capturing data in vehicle registration information systems. This method features the lowest quality of data captured, i.e. VIN error rate. Incorrect, unrealistic VIN values may be shown in the documents. During the copying process, the user may make unknown, unintentional errors (misreading the VIN entry from the document, typing it incorrectly, swapping adjacent VIN characters due to finger motor skills on the keyboard, etc.). Deliberate errors in the VIN entry in order to change the identity of the vehicle, so that it cannot be checked against, for example, police tracking systems containing stolen vehicles, are quite common as well.
