card device

I need magnetic ultra small magnetic card reader to be designed and implemented and to be placed in a device which i can give to you. There are 2 variants of implementation and please tell me which of them can you do, price for it, and time for implementation.

1 variant - audio magnetic card reader:

This variant uses audio device and reads the information stored on track2 of the magnetic stripe of the card and saves all information as .mp3 or .wav format. The device must be ultra small and must work for at least 5-6 hours using a clock batteries. The device must read in both directions. Also it must be able to be recharged when the batteries run out and also to have ability to download the information to PC without destroying the device for exmaple using USB cable.

2 variant - magnetic card reader implemented with microcontrollers:

In this variant the device must be ultra small and must read in both directions and read the information on track2. It must be able to be recharged and to run on clock bateries and to operated at least 5-6 hours. In order to sve batteries it can be implemented to go in sleep mode when no reading. In this variant it must be programmed to save the information in ASCII format and the file where the information is stored must be password protected or encrypted. Only me must be able to open the file with the stored information. All the information must be checked for errors (LRC) and each infomation must be stored by date and time, for example:

(date) (time) (record1)
