// Notes for ISO14443-A emulated tags:
// * Only short UIDs are supported
// If your UID is longer it will be truncated
// Therefore e.g. an UltraLight can only have short UID, which is
// typically badly handled by readers who still try to send their "0x95"
// * First byte of UID will be masked by 0x08 by the PN53x firmware
// as security countermeasure against real UID emulation
// Example of a Mifare Classic Mini // Example of a Mifare Classic Mini
// Note that crypto1 is not implemented in this example // Note that crypto1 is not implemented in this example
