Do not purchase.
I purchased this app for a couple reasons. The ability to scan code 39 barcodes and also to be able to consolidate the cards carried in my wallet. It did not scan the code 39 barcodes as advertised and also did not store the "avatar" of the grocery store card I tried to add, making it impossible to differentiate between multiple cards added. Complete waste of 99 cents.
