Check the capture setup before the price
A computer is fine: check the software release, operating system, processor, graphics and memory against your actual machine. For a Mac, match the chip, memory and app before comparing packages. Original EINSTAR and MetroX requirements differ from those of EINSTAR 2 and MetroX Pro. For MetroX on a Mac, confirm the exact Revo Metro build, processor support and any translation software it needs.
You want to use a phone: check the named capture mode. POP 4 laser capture needs a computer; compatible phone capture applies to infrared modes. Before buying for an iPhone, confirm that the required iOS app is available for your model and capture mode. Creality's compatible phone workflows can require the optional Scan Bridge, which the Raptor and Otter base offers here exclude. Include the bridge and any additional phone in your budget, then check processing and export on that exact setup.
Check the POP 4 mode and phone requirements ↗ and Creality's mobile capture instructions ↗ for your chosen setup.
You need capture on the scanner itself: check that your chosen model documents that capture path. Compare capture setups in the full catalog or change that answer in the selector. A wireless link to a computer is a different setup.
