I like most how it's able work with our software already installed at my store so no need to install new one. It also works well if you want your customers' information secure which we do since this are very important data about them (like names etc). Nothing really dislike but maybe sometimes when there isn't enough space left or other problem happen during login/logout session then some things might get lost from users info such us phone number where they have entered previously before logging out. This product help me manage all type of people visiting into retail stores including sales associates.
