:?: I’m a model railroader and I want R/W RFID chips to fit under HO scale (like your read only button size) I see a ID-20RW but I can’t find any more info. Can you provide me with a link to your page and info about which tag to use? I like the glass tube, can they be R/W? An off layout writer would be fine as it will be used mostly for initial installation.
Hello jwk.
The [glass RFID tags we carry are not writable, but we do have a MIFARE laundry tag that’s small and can be written too. You’d need a reader like [SM130 to read or write those tags though. We don’t have a hookup guide for this reader/writer but we do have a [Arduino shield that includes an antenna and that has some example code to get you started.
Just to let you know, these are not really plug and play components and they are going to take some work and programming on your part to get them working. They are more of an advanced level product.](https://www.sparkfun.com/products/10406)](https://www.sparkfun.com/products/10126)](https://www.sparkfun.com/products/9416)
