Options to know if you will get the "3 Beeps" (cleared for PreCheck)
Since there are 4k+ posts to date I thought it might be helpful to summarize 2 ways to sort out, once enrolled in Pre, options to scan and read barcodes on an iPhone. There may be other options.

1) Print out your BP. Download Manatee Works barcode scanner app (free). Start the app and position about 6" over the barcode. Read and/or copy the scan to Evernote. I delete everything to the right of my AAvantage #.

For this approach, it is not necessary to waste the paper by printing the BP. The Manatee scan works just as well with the pdf image on the computer screen. In both cases, it can take a bit of time, and options 2) and 3) below are better and faster

Next assess your Pre status on this BP: On Manatee I always have an open or blank field immediately to the left of the field before 'AA AA' followed by my AAdvantage number. If the next field to the left of the open field is "3" I've always sailed thru Pre. Like this:

M1xxxxxxx/xxxxx/ 6 digit record locator/DENDFWAA 2096 160X006E0068 148>218 WW0131BAA 00000000000002900100123227983 AA AA xxxxxxx EXP

2) With the AA app, save your BP to Passbook. This is in the Aztec format, which is square. Download the Qrafter barcode scanner app (free).

- Open Passbook and find your BP. Take a screenshot of your mobile (Passbook) BP: press the home button (at the bottom) and the power button (at the top) simultaneously. This saves your Passbook BP to your iPhone photos.

- Open Qrafter,and choose to scan a picture from photos. Opt for move and scale to center the Aztec code. Access the BP 'photo' and scan the Aztec code.

- Read the results as you do with Manatee and save if you like to Evernote. I have noted that with the same BP ( one printed and read with Manatee, one on Passbook and read with Qrafter) that on Qrafter the open field between the "3" and AA AA... now contains a digit - often a "2" . Like this:

M1xxxxxxx/xxxxx/ 6 digit record locator/DENDFWAA 2096 160X006E0068 148>218 WW0131BAA 000000000000029001001232279832AA AA xxxxxxx EXP

On this trip anyway, I cleared Pre at DEN with the Passbook BP. Some of the fields left of the AA # apparently indicate whether or not you are Pre enrolled and 'eligible' but I don't know if that was the 9, 8, or 2 in my case.

3) Have the mobile BP sent via the website. Open this on the phone and save the QR image to the Photo Roll simply by touching it. Then feed this to Qrafter. Since this contains only the QR barcode, it avoids the need to do any move/scale operations.

One thing to note is that if you get an agent printed BP, they show 31 and not 32. It is of course the 3 that makes all the difference.
