// #############
// Example: MIFARE Ultralight EV1 and NTAG 213/215/216 – implementation of card's specific commands
// - note: for instructions on reading and writing the data,
// please see read-write.js, which is common for all ISO/IEC 14443-3 tags
// - note: this guide applies to NTAG 213/215/216 cards as-well
// (the commands and configuration pages structure is same or very similar,
// the only difference is the location of the pages due to different user memory size)
// - docs (descriptions of the commands and data structure):
