HI,
I have a special project i try to understand and reading.
This is originally an SD Card which has credits on it, chinese card works with an Android Panel. When you make online purchase it's adding credits on the card for copy or print.
The pictures shown a 16 pins, look like EEPROM that read and write when you add credits. I think it's a SPI EEPROM and i would like to know who to read it and learn hacking the SD CARD.
First, i was thinking about it's was a basic SD Card, but after opening the card, it has only that SPI chip.
The Chip shown TS201 or TS20I with numbers 1619 (possible TS201 1619 or TS20I 1619). It's works on native sd card power. IF connected to a PC, it's doing nothing. It's needing a SPI programmer, which i have. I have a MiniPro Programmer.
I need help for identifying this chip. I search over baidu and google and not found anything with theses numbers.
Any help is appreciated.
Thanks
