The wet inlay is the most economical tag in our store, but it still packed full of features. It contains an NXP NTAG213 chip with a built in UID and scan counter. Like all NTAG213 tags, these tags are lockable and can be protected with a password. With 137 bytes of usable memory, these tags are great for embedding in other products, when printing is not required and they will be protected from the elements. They are round clear tags with an adhesive backing.
