 20 Jun 2005 11:20 how to start to develop SIM card reader |
|

good day,
I wish to develop a sim card reader/writer, wish able to backup the data inside the card, and restore it back to another sim card.
I wish to know how to start with.
as far as i know, Maxim has MAX1740, MAX1741 level shifter.
perhaps i will use PIC as controller. I don't know how to control the Sim card.
I guess Sim card is one of the smart card, and those circuit might be the same
Thanks.

Thanks tcsa35.
here are some questions more.
1. What's the relation between smart card and sim card?
2. There are quite a number of smart card reader from the web. Can I
use smart card reader to read sim card? I found one smart card reader IC from Atmel as well.
3. What is gold card / silver card? where can i get them? i couldn't
find it from microchip.com.
4. What uC is used in sim card? mine have "GEMPLUS" printed on it. Is
that a pic or avr?
5. Are the sim cards using same file system, regardless the phone
model and service provider?
6. What protocol and the filesystem of sim card?

>"Gold & Silver Wafer Programmer"
Thats for cards containing a microchip technology pic processor, it is not for SIM cards.
>1. What's the relation between smart card and sim card?
A smart card is a card that is smart, that term is used to refer to payphone cards, chipa-and-pin credit cards, satellite TV cards, ecash cash etc. A sim card is a Subscriber Identity Module for a mobile telephone.
>What is gold card / silver card? where can i get them?
Google. They are mainly used for pirate satellite TV cards.
>What uC is used in sim card?
Sim cards are not microcontrollers, they are ASIC's.
>Are the sim cards using same file system, regardless the phone
>model and service provider?
GSM sim cards work in any GSM phone (network locks allowing).
