    Good reader

    2016-07-07 01:30:44

    Works very well (from about 4cm already), but watch out for the output. As I'm from Belgium, my keyboard layout was AZERTY, which gives strange results in scanning output, make sure it's set to QWERTY. Apart from that, read the other review in here that explains how the ID is read, that helpen me to figure out how to parse the data.

    Works fine - comments on interpreting output

    I am also using RC522 readers with Arduino for an application and bought this unit as a way to check cards/tokens. It only reads the card ID and not other card data. e.g. good for use as a simple ID token reader. This acts as an input device - so will send the CSN/ID of the card as if it had been typed in from a keyboard e.g. focus needs to be on an input box when a card is read. The card ID is the only thing read, this is 4 bytes in decimal format. The card ID bytes are in reverse order with this

    very good product

    The product is excellent, reads easily the cards. One point that could be great would be to have a possibility to program wether the keyboard wedge sends data as upper case or lower case, or just emulate a keypad stroke.

    Works perfectly - limited read zone

    So the product works as advertised and is immediately recognized by windows 8.1. The area that reads information is rather small so if you need something that reads from a surface larger than a US penny then buy something else.

    Plug and play easy

    Just plug it in and this little device scans cards and fobs and outputs the id as if you are typing it at the keyboard.
