The developed wireless multi-channel PPG system comprises tiered communication subsystem with two sensor modules and a single base module. The sensor modules process the input signals simultaneously into 16-bit samples and wirelessly transfer them to base module using Bluetooth technology. In base module, the samples are combined using time division multiplexing into composite stream and serially forwarded to the host computer. The string buffer is implemented in the sensor module firmware to increase the transfer time, transfer samples in chunks and eliminate the wireless transmission latency. The wireless network is established between modules. The newly implemented firmware results in... 

Mobile banking (M-Banking) has been welcomed in most of the countries as a new branch in electronic banking (E-Banking). In developing countries such as Iran mobile banking is limited to fields such as SMS due to lack of infrastructure and because of high costs.
