The growing popularity of connected devices and the booming internet of things market have generated enormous profit potential for manufacturers of radio frequency (RF) transmitters, including RFID readers. The world is developing, testing, manufacturing and selling RF equipment. Common RFID readers on the market are:Manufacturer hologram sticker PVC printed card，2 or 3 tracks Java J2A040 Card，FM5542 Smart Card，40K/80K EEPROM Java Card，Dual Interface J3D081 Card，ISO15693 RFID Smart Card .To control production costs, many manufacturers selling equipment in the United States conduct design and regulatory compliance testing overseas.
Then, in recent months, the development costs of manufacturers that conduct R & D and equipment testing in many overseas countries will grow rapidly as a result of the Federal Communications Commission (FCC) restrictions.
Currently, FCC began to remove the authorization of various testing laboratories. This will also have a negative impact on the manufacturer's sales in the United States.
