You can use the application to attach things like videos, text, or files onto any physical item by scanning the barcode through the application.
I don't bank with Chase anymore, but I kept the app on my phone because I do still have a credit card with them. I always remember I couldn't log on for some reason... I only kept it to find nearest ATMs on my phone.
I like mobile bank apps, if they're designed well. This one is. They're also useful when used with the Mint app and the Pageonce (Personal Assistant) app.
