Laptop scanner online
And for that a business card scanner is one of the most useful devices. Of course if you have been in business for a while, you probably already have a Rolodex that you put to regular use. However, a Rolodex can get filled up in a surprisingly short time, and you will have to pore through it and discard the business cards that you don't need sooner or later. This shouldn't be a problem in most cases, unless you need to find a contact that you had inadvertently thrown out. This is only one situation wherein a business card scanner could have avoided a lost contact.
