As someone who is always on the go, I often find myself scanning documents and receipts while on the road. Because of this, a scanner app is a must-have for me. In my line of work, I work with different clients and I often have to reimburse some expenses. To do this, I need to keep copies of my receipts.
I use Microsoft Lens simply because it is a Microsoft product and I am sure of its security. Honestly, I was using CamScanner before and then I uninstalled it immediately when the news came out that it can be compromised. I don’t want that to happen again so I went with MS Lens.
So far, I am liking it because of the enhancements it can do to the scanned image because sometimes the original image just won’t cut it.
