Presumably, encryption would add hardware costs to a device that they're giving away tens of thousands off for free, and only provide the illusion of additional security on top of there existing security measures once it hits the iOS client (pure speculation on my behalf).

This would prevent the device from being useful for anyone but Square. It may not be worthwhile to do so, but it certainly isn't the illusion of security if your concern is accessing the raw data.
