^ if we have not used or seen the scanner or reader before, then Apple has new reader/scanner which they put it in next iPhone.. but it is not actually new because we have seen/used the reader/scanner on the previous devices such as laptops, on office walls, etc.. in the past.
Besides, I don't care if the companies put old tech in their upcoming products/devices... it is up to them. If you don't like it, then don't buy it or if you like the device except the reader, then you can keep it turned off.. but you will have to use the reader at the job so you can be clocked in/out.
At the retail stores, you can see the employees walk up to the reader on the wall near the customer service.. which you could see his/her finger on it to be scanned so he/she can be clocked in or out. Depends the locations, some stores have old fashioned devices such as punch clock, something like that.
