IrRedyIrFront is ACCESS’ original compact embedded IrDA protocol stack. IrFront was developed primarily for mobile phones and other resource-restricted embedded systems. IrFront is compliant with IrDA specification for infrared*. In Addition to standard feature support like IrCOMM and IrTran-P, major functions like IrFM for IrDA financial services as well as IrMC for OBEX are available as options. IrFront has been widely deployed on mobile phones, and has been used for both data exchange and financial services. Supporting such diverse services ensures broad compatibility with many systems and devices, including digital cameras, mobile printers, POS (Point-of-Sale) systems and more.
