Bluetooth MFi is Apple’s licensing program for hardware and software specific to their iDevices. MFi, or Made for iOS (iPod/iPhone/iPad), in hardware like the Scanfob® 3002i denotes a special Bluetooth connection mode called IAP. IAP is similar to SPP on Android — which allows a peripheral device to connect as a virtual COM port. This capability allows software developers to interface peripherals directly with their apps. Simulating a virtual COM port means that scans are sent faster and more reliably. Simulated COM ports have the additional benefit of being able to send special characters or information that you would not be able to send using HID (keyboard emulation). All Serialio apps for iOS allow for MFi compatible scanner connectivity. These apps include (but are not limited to) Mobile Grid, Mobile Order, SerialMagic Keys, RS3 NFC Setup, yACK BLE, and iScanBrowser.
