1st says IR but it should be NFC.
3rd says NFC when it should be IR.

No.# A -- magnetic reader (NFCU has these at the workstations)
B -- Signature pad (for customers to sign)
Not D -- Web camera (for each workstation? Security cameras should be centralized from a server.)

No.# 1) The first factor is a processor (with liquid cooling)
2) Second is RAM.
3) Third is the GPU (graphics processing unit).
4) Fourth is the SSD/HDD
[Since processor is not in the list then assume liquid cooling is not a factor?]
