fake currency Current Affairs - 2020
The Council of Scientific and Industrial Research (CSIR) and National Physical Laboratory (NPL) developed an ink to combat the problem of fake printing of passports and counterfeiting of currency notes. The ink has a new security feature o protecting itself against duplicity
Key facts of the discovery
The ink was produced based on single excitable dual emissive luminescent pigment. It was developed based on the concept of fluorescence and phosphorescence phenomena. Currently, the currency notes display only one color with the emission of wavelength. However, in the ink developed by the scientists features changes in pigment color after the notes are printed.
In ambient light the ink shows white color. When the ink is exposed to UV light, it turns red and when the UV source is switched OFF it turns green.
Why the new ink?
According to the annual report of RBI (2018-19), the risk of duplication of Rs 500 and Rs 2000 notes are higher. The report says that recently launched 500 rupees notes are accounted to 121% of duplication and Rs 2000 notes are accounted to 21.9% duplication.
Fluorescence and Phosphorescence
Both in phosphorescence and fluorescence the radiation is electromagnetic and is spontaneous.
In case of fluorescence, the radiation stops after the source is switched off. On the other hand, in phosphorescence, the glow continues for few hours.

The government has issued orders to suspend the Line of Control (LoC) trade between Jammu & Kashmir and Pak Occupied Kashmir (PoK).
Why did the government suspend LoC trade?
- The LoC trade was initiated to facilitate the exchange of goods of common use between local populations across the LoC in Jammu & Kashmir.
- On the contrary, the reports indicated that Cross LoC trade routes were being misused by the Pakistan based elements for funnelling illegal weapons, narcotics and fake currency etc.
- NIA probes also indicated that a significant number of trading agencies engaged in LoC trade are operated by persons closely associated with banned terror organisations involved in fueling terrorism/separatism.
The notification by the Ministry of Home Affairs has stated that it has decided to suspend LoC trade at Salamabad & Chakkan-da-Bagh in Jammu & Kashmir. Further, a stricter regulatory and enforcement mechanism is being worked out & will be put in place in consultation with various agencies and the issue of reopening of LoC trade will be revisited thereafter.
