The first method: If you don't have to keep the contents of the original card, you can do this:
First, treat it as 8515 card, then write the card according to the method of writing 8515 card. If you can verify the success, you can confirm that it is 8515 card.
If it is not the 8515 card, write the card according to the method of writing 877 card. If the verification is successful, it can be confirmed that it is 877 card.
Even the 877 card is not, generally it can be judged 84 card, the same can be confirmed by writing 84 card.
If you want to judge the external storage capacity of the card, that is, whether it is external storage such as 24C16, 24C64, or 24C256, you can try to use the 24C16, 24C64, or 24C256 capacity file when writing the external EEPROM. If it succeeds, it will respond. External storage.
The second method: you judge whether it is 8515 card or PIC card (84 card, 877 card) according to the circuit.
As shown below, 7 of the 8 contacts for the 8515 card (the 6th contact is not connected) to connect to the chip, and 84 and 877 cards, only 5 (No 6, 6, and 8) Connected, that is, there are 3 redundant contacts, you can use a multimeter to measure the resistance of the three contacts to other contacts to determine whether it is 8515 card, or PIC card (84 card, 877 card).
The third method: according to the price, the general price of less than 30 yuan should be bought 84 cards, 8515 and 877 prices are basically the same, it is not easy to distinguish.
Often people will judge according to the shape of the metal piece in the card or even the color appearance of the card. Last year, there was a certain role, but now the card dealer basically finds what card base to use. The original 84 card is often used in gold. Yellow, but now I have found a head card, gray or even white 84 card.
