Welcome to our store.  Our one product is the Phillips/NXP Hitag S 2048 2 x 12mm glass RFID tag.  These tags are not sterilized so they will require a bit of sterilization or sanitization before being placed into a living creature.  They do not have any type of anti-migration coating on them so should the need arise removal will be easier than if there was a coating on the tag. Each tag also comes pre-programmed with it's own unique 10 digit ID code (HEX 0-9 A-F) so that the tag can be read by any standard EM4102 reader and to top it all off, if you have a Hitag S writer you can change the code. If you have a specific code you would like programmed into the tag just let us know in the checkout notes and we will be happy to do that for you.  For more information or to order click here.   If you have any questions check the spec's on the product page before placing your order or send an e-mail to the address listed in the "Contact" section of the site.
