I am looking for someone with high experience in GSM/GPRS and SMS data transmission. I need the qualified bidder to build a GSM Magnetic Stripe Card Reader. After the card has been swiped, the data has to be sent via the GSM module to a phone number of my choice.
Also most importantly the reader must be able to read interrupted swipes. (If the card is swiped half way and then back out and then forward in a fast,slow or jitter motion), the magnetic reader can still read the data from the card.
It also must have a long life rechargeable li-ion battery. The device is required to be portable, so the PCB is required to be as small as possible.
