The Election Commission has decided to introduce QR code-based identity cards at counting centres to prevent unauthorised entry during vote counting for Assembly elections in five states on May 4, an official said on Thursday, the PTI reported. 

Implementation across states and future expansion

The system will be implemented on counting day for the Assembly polls in West Bengal, Assam, Kerala, Tamil Nadu, and Puducherry, as well as for bypolls in seven Assembly constituencies across five states. It will later be extended to all Lok Sabha and Assembly elections, the official said.
