A Portable Bluetooth Printer is the product of microcontroller based interface and prints the text, numbers, and characters on the paper. A user can send SMS from a mobile phone-based application which is transferred to the microcontroller based system on Bluetooth signals. Our system makes use of a microcontroller based circuitry interfaced with a printer to achieve this purpose. The system makes use of an android application to transmit the text data to be printed through the printer.

The Encrypted Magnetic Head both clear and encrypted text date output. If the encryption function is not enabled then the user can set output format of the data decoding such as setting the prefix characters, characters etc. It reads interrupted swipes in both directions and reads all magnetic cards. There is data retained even if power is removed.

Magnetic Card Decoder is the most popular product in western Europe, domestic market, and South America. The magnetic card is the ideal for access control, timekeeping, ID recognition, banking, credit verification and related application. It has programming software for various read/ writes performance. It is most useful for reading and writing drivers licenses.

A Schottky diode is an electronic component which is necessary for the operation of the circuit. It is used to radio frequencies, RF functions as a mixer or a detector diode. Schottky Diode comes useful for functions having power because of processing low forward voltage drop that would result in power loss at the least level in comparison to the general PN junction diodes.
