Fraud Rings Exploit LINE Screen Sharing to Steal TWQR Payment Codes

TWQR is a common payment standard developed by Financial Information Service Co. in partnership with financial institutions. Its payment codes can trigger direct debits from linked accounts, making a leaked code akin to handing over a wallet. Since March 2026, fraud rings have combined fake online sales, bogus delivery services and LINE screen sharing into a social-engineering chain, showing how the convenience of mobile payments can also be turned into a channel for real-time money laundering.

Taiwan's Criminal Investigation Bureau announced the results of its “Code Sweep” operation on June 22, 2026. Police conducted coordinated raids across Taiwan from April 27 to 30, arresting 117 suspects, 41 of whom were detained in custody, and seizing 33 mobile phones and NT$270,000. A preliminary investigation identified 1,341 victims and losses totaling NT$130 million. Joint fraud-prevention efforts by police and banks subsequently reduced the daily caseload from about 300 to roughly 10.
