When I scan ANY card, I always get 2 values each. I tested with a commun usb card reader, FYI. The IDs I get are: Device 1 (same as USB reader) = 0006628180. Device 2 (The odd one) = 10109044. Beware that this is the same card. I have other examples if you want. I can think of two reasons this may be happening: 1) CRC or checksum . When I scan ANY card, I always get 2 values each.

I can think of two reasons this may be happening: 1) CRC or checksum calculations at the start vs. end of the tag ID (vendors may implement this differently) but it sounds like you've already investigated that. 2) The readers are configured to read different areas of the tag. I have two different RFID readers which both give different outputs. One RFID readers is this one from dealextreme: http://dx.com/p/intelligent-id-card-usb-reader-174455 It is plug and play. Of the.
I have a lot of RFID cards that I'm using, but around 1/4 of them does not work with the code I have. First off, I have an USB RFID card reader that I use to read and program the RFID cards, plus store their hexadecimal values to our SQL database. Measure the output of the reader with a multimeter. You should see 5V when there is no card present. If you see 0V here then the signal needs inverting with a transistor. For proximity tags (predecessor to modern RFID) which used lengths of up to 37 bits, it was very common for readers to output the data as octal digits. Although hex is in many ways preferable, devices that expect data from magnetic .
On my RFID TAG is the number "0007912551". The serial monitor says "9 9 8 8 5 6 6 7 4 5 6 0". I used to work designing RFID readers and access control systems. Often the number printed on the tag has no relationship with the number stored in the tag. Encoding your RFID tags becomes very important in a couple of different scenarios common in the RFID industry: If you purchase a roll of RFID tags that all have the same EPC number, and your application requires each tag to have a specific set of numbers.
I have a pretty generic NFC reader that simply emulates a keyboard and outputs an 8 bit string of numbers when it scans an NFC tag, then hits enter. I wanted to find out how it’s determining this number and, after looking back at the listing, noticed it states that the output is “2H+4H (8 bits).” When an access control card (the RFID tag) is shown to the access control reader next to the door (the RFID reader with RFID antenna), that specific number is sent to the access control panel (a physical controller).
