Depends on how you define airgapping. If it's a fungible "you know what I mean," well then obviously yes. If it's an actual air gap, then no. Practical busin

Depends on how you define airgapping. If it's a fungible "you know what I mean," well then obviously yes. If it's an actual air gap, then no. Practical business requirements on inventory management, sales metrics, system administration and (funnily enough) payment processing all prevent a register network from being airgapped. If you want to say their protection of those communication channels was shit, well, we already have proof it was. But airgapping? Not so much.
