Ah ha! Thanks. When I went through nfc-list source code it seemed to be trying 10 different “types” of RFID:
printf("\t 1: ISO14443A\n");
printf("\t 2: Felica (212 kbps)\n");
printf("\t 4: Felica (424 kbps)\n");
printf("\t 8: ISO14443B\n");
printf("\t 16: ISO14443B’\n");
printf("\t 32: ISO14443B-2 ST SRx\n");
printf("\t 64: ISO14443B-2 ASK CTx\n");
printf("\t 128: ISO14443B iClass\n");
printf("\t 256: ISO14443A-3 Jewel\n");
printf("\t 512: ISO14443A-2 NFC Barcode\n");
which it’ll print out if you use the -v option, so I had hopes one of these would be the same and it would at least “notice” the LTO-CM, thus testing whether any particular ACR122UA9 was LTO-CM-compatible or not.
