Review on YARONGTECH RFID Chip 125Khz EM4100 by Justin Garrett

I recently purchased an RFID chip for my company`s commercial access control needs. As a result of using this product, I found that it is a perfect fit for our requirements... The chip operates at 125Khz, which works well with our existing systems. It is also durable and can withstand daily usage without any problems. The chip is industrial and scientific grade, which provides additional peace of mind. The only con is that it requires additional programming to integrate with certain software. Overall, I highly recommend this product for any commercial door products in need of reliable access control..
