He said the bids would soon be invited by the Central Board of Direct Taxes (CBDT) in this regard to issue PAN cards with biometric features.
The biometric PAN card could use "iris" scan for identification. This means that one might have to provide fingerprint or iris/retina impression.
The Income Tax department had mooted introducing such cards about two years ago, when it found that over 13 lakh people out of about total four crore PAN card holders had duplicate cards.
Most of them had provided wrong information about their home address or even furnished different names in the column of father's name to get two or three PAN cards.
The move has been, however, delayed due to lack of consensus in the department over the use of technology and due to high costs.
Currently, a PAN card costs about Rs 60. A biometric PAN card, however, will cost anything between Rs 200 and Rs 300, sources said.
Chidambaram further said the biometric cards would be introduced only for new applicants, and "old PAN cards will be valid".
