Most likely you would import function starting with a word "validate":
``js
// Hong Kong ID card (Supports two leading letters):
import { validateHkid } from 'validid/hkid';
validateHkid('AB987654(3)'); // returns { id: 'AB9876543', ok: true, ... }
// Taiwan ID card (including National Identification Card and Resident Certificate):
import { validateTwid, identifyTwidType, identifyTwrcVersion } from 'validid/twid';
validateTwid('A123456789'); // returns { ok: true, ... }
// Some services still need to identify NIC and RC:
identifyTwidType('A123456789'); // returns "NIC"
identifyTwidType('A800000014'); // returns "RC"
// And even to identify old and new RC:
identifyTwrcVersion('A800000014'); // returns "RC_2021"
identifyTwrcVersion('AB12345677'); // returns "RC_LEGACY"
// Korea ID card:
import { validateKrid } from 'validid/krid';
validateKrid('781030-5668081'); // returns { id: "7810305668081", ok: true, ... }
// No checksum is required according to latest system:
validateKrid('7810305668082'); // returns { id: "7810305668082", ok: true, ... }
// China ID card:
import { validateCnid } from 'validid/cnid';
validateCnid('120103198806018241'); // returns { ok: true, ... }
