Hex has launched a new iPhone 4/4S case that features a shielded internal storage compartment for an RFID-enabled card. The Hex Stealth Case offers protection for the back and sides of the device, and features raised corners that improve screen protection. RFID-enabled cards stored within the case can continue to be used for tap purchases without creating any cross-interference with the iPhone's antenna. The Hex Stealth case can be ordered online for $35 in both black and white models.
