Question

Mobile devices

The task is as follows, if the device that will act as a portable document scanner and as a device for sending them after scanning via the gprs channel (i.e. it has a sim card installed), (PS has climbed all Chinese sites, there are only hand-held scanners with memory cards miroSD).
It is even possible to take a device (scanner) simply with a memory card, that is, is there a device (small inexpensive) that will send the contents of the memory card by pressing a key to the mail.
