Factory Direct sales: cool card reader microSD/TF card/mobile phone memory card high speed 2.0 card reader

1. How to buy a card reader?

1. Look at the chip: at present, the chips with relatively stable market come from several brands in Taiwan: Qiyan Jianrong Chuangwei, among which Jianrong can surpass 360 and Chuangwei has the fastest speed; Some factories adopt chips of a domestic brand, this type is not very stable, and large files are sometimes disconnected, and can be transmitted after several attempts.

------- Our factory uses Taiwan rock chips.

2. Look at the Shell:

(1) Materials: Shell materials are divided into environmentally friendly materials and non-environmentally friendly materials;

(2) gloss: whether the gloss of the shell is bright or dim;

(3) shell wedge: Card Reader shell is assembled together with up and down 2 buckle. Some manufacturers do not buckle the inferior shell tightly, and it is easy to pry the two shells open with a small force when inserting the memory card.

(4) aesthetics: classic cool card reader is widely used, and its length, width and thickness are 4.8*2*0 respectively. 6cm is a reasonable size ratio. In order to save costs, some factories reduce the shell length to 4cm, which is out of proportion.

------- The shell of our factory is made of environmentally friendly materials, bright color, well-wedged shell.

3. Test method: now we choose to use a full test card reader. The full test can be divided into full test of insert memory card and full test without insert memory card. The test without insert memory card can only test whether the circuit board works normally and cannot test whether the memory card can be read and written normally; only by inserting a professional instrument into a memory card can we test whether it can read and write normally.

------- Our factory tests the read and write function with professional instrument card.
