I havent used it in a store yet but loading card data is easy and best of all it syncs to my wifes two iPhones her iPad and my 3 devices. I love the concept of having all my cards with me in my phone and more room in my wallet.
I used it several times and it has been very convenient. Some stores scanners cant read the barcode but the numbers are large and easy to read so they happily enter manually.
