In an effort to illustrate further what I'm talking about in regard to the terminals, I'll share with you this candid ditty. Everyday I hear my customer's frustrations. Everyday I also am frustrated with the process of explaining to them the simple process of waiting for the total, agreeing to the amount, and swiping their card....would you believe that even after instructing customers countless times a day how to use them. If I'm making a purchase through them, I will often swipe first and then wait for a total even though I know how to use them. My company isn't as much pompous as it is cheap. The OS that we use was written in the 80's. It infuriates me that they haven't upgraded it or many of the other processes that would be very cost beneficial to fix. But, I'm low on the totem...
Tags, whatever you want to call them, are useful. That's why they've been adopted. This shouldn't be a controversial point. I'm willing to spend a lot of time exploring the best way to implement them, but I'm pretty firmly convinced that a feature that has become commonplace elsewhere shouldn't be treated cavalierly just because we're "trying something new."
