My Starbucks is a barcode.
My Library card is a barcode.
My grocery rewards points are barcodes.
My Airmiles is a barcode.
My gym membership is a barcode.
And all of these are just some of the ones routinely scanned AS a barcode.
If I use LastPass to store that info I either have to type in a long number myself or tell the person behind the till/desk the number to type it in.
Why the heck can I not just ID it in LastPass as a commonly used barcode and in the UI on my phone press the barcode icon next the the account number and it kicks in a full screen barcode depiction of the number and turns up the brightness so that I can flash my phone at the scanner and proceed.
