Matters needing attention
1.The standard reading distance of the card reader is 5-15cm, the reading distance of the ID card reader is slightly longer, and the reading distance of the IC card is slightly shorter. If you use a keychain-type proximity card,the reading distance will be shorter, generally 1-3 cm. The way to read the card, it is recommended to use the card to face the card and naturally approach it, and the card reading method of using the card to quickly swipe from the side is not advisable, and the success of the card swipe is not guaranteed.
2.The card reader is installed on a metal surface. Since the card reader is a radio frequency product, the metal pair near the front or the rear will absorb its radio frequency signal. If the metal surface is large, it will even affect the card reader. card, or the reading distance is very attenuated.
3.The distance between the two card readers will also affect the card reader, some will shorten the card reading distance, and some will cause the two card readers to read the card at the same time or the card reader cannot read the card.
Solution: try not to install it on a metal plane, or dig out the back of the card reader against the metal part, and keep the distance between the two card readers more than 25cm.
