Scan the back of your license / permit using a medium - high resolution. The resolution should be set so that the 2d barcode is about 2000 pixels long. Open up the image in Photoshop and cut out the 2d barcode. The 2d barcode is the one on the bottom in the picture.
I am given a task to develop a small library which needs to be able to read PDF417 barcode located on the back of the Driver's License card and parse the data out to our custom object.
However I need to know what data types are these Data types denoting?
The complete documentation can be found at: http://www.dol.wa.gov/external/docs/barcodeCalibration-basic.pdf
Guessing here, but <field length>/ANS, where A is alphabetic, N numeric and S spaces?
For example, 3/A is 3 alphabetic characters like USA.
Funny that weight and sex are both 1/N, but the example given (2 in both cases) fits my hypothesis.

The Washington spec is based on the AAMVA standard here:http://www.aamva.org/DL-ID-Card-Design-Standard/
The 2013 ID Card Design Standard is here: http://www.aamva.org/WorkArea/DownloadAsset.aspx?id=4435
The PDF 417 barcode specifications start on page 51 (65) of that document. On page 58 (72) they list the type definitions: 'A=alpha A-Z, N=numeric 0-9, S=special, F=fixed length, V=variable length'
6 A/N means it is a 6 digit or spaced (A)lpha/(N)umeric variable. For example 5'7' could be expressed as a variable that would fit the format as '067 in' (quotation marks only enclosing the actual variable. Very common definition of terms usually found in Database programming. Your variable will always be 6 characters long (including the space character)--3 alpha ( in) and 3 numeric (067).
