Can this reader ready multiple RF tags at one time? The EAS tags for anti-theft purpose.

HI, You'd better not do it , as the different labels will cause interference.

BTW,card can’t be read again within the range of read antenna after read once. User must move it out of reading antenna range first, swipe card again & can be read.

Will this read the tags that are implanted in pets (US based)?

Hey alanv73 I can confirm that this works with implantable chips, I have one in my hand and one in my dog, both work with this reader. however I know there are some proprietary chips out there such as the avid brand which i havent tested, so your mileage may vary

Hello folks. I bought EM4100 tags from Amazon and this 125khz reader works great with them. But, the tags are printed on the outside with a unique code that is not the same as the ID that the reader sees. How to correlate the tag's printed code with the ID seen by the reader? Example: tag printed on plastic "0009429268" and reader sees "000042E1E5" in UART/TTL mode. Thanks!

Answering my own question here... because I matched up the wrong TAG with the reader output. The value printed on my plastic tag is the decimal representation of the first 10 bytes of the reader output. So if the reader gives me 000042E1E5, then the tag should be printed with 0004383205. Easy enough when you organize your data correctly.
