Many wireless applications in the world require identification and authorisation of a device or a person for carrying information. Also there is a need of transmission schemes for transmitting such signals to the host computer over the network. In such applications different tools are used for authentication, that includes barcodes, magnetic stripes, chip cards, RF tags, iButton, etc. Similarly, different wireless technologies are available viz. Bluetooth, ZigBee, Wi-Fi, etc. A review of different applications based on ibutton and ZigBee used for accessing and data transmission schemes are discussed in this paper.
