Problem description:
Can dual-voltage RS-MMC card be used on QD? Is it better than ordinary mmc card?
Analysis:
Yes, just plug in the card holder (take it with you when you buy the card, and use it without removing it). My buddy uses QD, and he uses PQI's 5 12M card. I heard that the best QD is PQI.
Most cards of other brands are too thin to be used on QD.
The full name of RS-MMC card is REDUCED SIZE MMC card, which is also a reduced version of MMC card.
But there is one thing you should pay attention to. The market price of 5 12M is generally around 250 yuan.
Be careful when buying, the price is too outrageous ~! Please read the following article to prevent the trap.
Authentication of MMC card;
Let's take PQI memory card as an example to talk about how to distinguish between true and false MMC cards.
(1) From the appearance, the patterns and characters printed on the surface of genuine PQI are bright, while the colors of counterfeit products are dim and the characters are not very clear; In addition, the bottom of the genuine product is engraved with a series of product numbers, but there are no counterfeit products.
(2) All PQI products are affixed with laser anti-counterfeiting labels. The real laser anti-counterfeiting label has the word "PQI", but the counterfeit product does not.
(3)PQI launched the 800-yard anti-counterfeiting system through the National Quality Inspection Association. There will be a service card in the package of the genuine PQI, and there will be a visible 800 telephone security code on the back of the card. Users can immediately identify the authenticity of products by dialing 800 toll-free telephone number and entering the anti-counterfeiting code on the card.
Look at PQI.
Jinyong International Co., Ltd. has been selling all over the world under its own brand "PQI" since its establishment. Its product lines include: memory modules, various flash cards, portable disks, card readers, disks on modules (DOM) used in industrial control market, etc. Not long ago, PQI Shanghai Marketing Center Jinyong (Shanghai) International Trading Co., Ltd. was officially announced, which also marked Jinyong International pushing its flash memory products to the domestic market. But before that, due to the imperfect domestic agency mechanism, the domestic market was flooded with a large number of counterfeit PQI products, and the share even reached 40%. In order to improve the current unfavorable situation and comprehensively crack down on counterfeit products, PQI has taken a series of anti-counterfeiting measures. This paper introduces the identification method of genuine PQI, and consumers who are going to buy PQI products must pay attention to it.
1. All PQI products are affixed with laser anti-counterfeiting labels. As can be seen from the picture, the real laser anti-counterfeiting label has the word "PQI" on it, but the counterfeit product does not.
2.PQI launched the 800-yard anti-counterfeiting system through the National Quality Inspection Association. There will be a service card in the package of the genuine PQI, and there will be a visible 800 telephone security code on the back of the card. Users can immediately identify the authenticity of products by dialing 800 toll-free telephone number and entering the anti-counterfeiting code on the card.
3. From the appearance, the patterns and characters printed on the surface of genuine PQI are bright, while the colors of counterfeit products are dim and the characters are not very clear; It is obvious from the figure that the green background color and the red word "Hi-Speed" of the 64MB and 128MB CF cards are obviously different. In addition, the bottom of the genuine product is engraved with a series of product numbers, but there are no counterfeit products.
4. Finally, there is the difference in price. One of the main ways for counterfeit products to occupy the market is relatively low prices, and with the gradual improvement of PQI product agency mechanism, the prices of all PQI products in the domestic market will be unified, so counterfeit products must be the kind with large price differences.
The quality and performance of counterfeit products are far from those of genuine PQI products, and after-sales service is not guaranteed. Therefore, once again solemnly remind consumers not to give unscrupulous businesses a chance to be greedy for cheap. After all, for storage products, you should rest assured.
