New Delhi, Mar 15: The new rules for debit and credit cards to increase security and reduce frauds kick in from Monday. In January, the Reserve Bank of India (RBI) had issued new rules to improve user convenience and increase the security of card transactions. These rules will help in curbing the misuse of debit and credit cards.

RBI has directed banks to allow only domestic card transactions at ATMs and PoS terminals in India at the time of issuance/reissuance of card. For international transactions, online transactions, card-not-present transactions and contactless transactions, customers will have to separately set up services on their card.

These rules will be applicable for new cards from March 16. Those with old cards can decide whether to disable any of these features.

As per the existing rules, these services used to come automatically with the card, but now it will start at the request of the customer.

Debit or credit card customers who have not yet done any online transaction, contactless transaction or international transaction with the card, then these services on the card will automatically stop from March 16.

The Reserve Bank has asked all banks to provide mobile banking, net banking option to enable limit and enable and disable service 24 hours a day, seven days a week.

If the customer makes any change in the status of the card, the bank will alert the customer through SMS/email and send the information.

Issuers shall provide to all cardholders facility to switch on/off and set/modify transaction limits (within the overall card limit, if any, set by the issuer) for all types of transactions -- domestic and international, at PoS/ATMs/online transactions/contactless transactions, etc.,

The provisions, however, are not mandatory for prepaid gift cards and those used at mass transit systems.

The latest instructions come in the wake of rising instances of cyber frauds and the huge increase in the use of cards.

Srinagar, Jan 9: Envoys from 15 countries including the United States were shown around Srinagar on Thursday, the first visit by New Delhi-based diplomats since the government stripped Kashmir of its semi-autonomous status and began a harsh crackdown five months ago.

The diplomats were driven by Indian authorities in a motorcade amid tight security from the airport to the military headquarters in Srinagar, where they were briefed on the security situation, an army officer said. He spoke on condition of anonymity as he was not authorized to speak to reporters.

They also held discussions with civil society members and some Kashmiri politicians, said Raveesh Kumar, spokesman for the Ministry of External Affairs (MEA).

The objective of the visit, organized by the Union government, was for the envoys to see first-hand “how things have progressed and how normalcy has been restored to a large extent'' in Kashmir since August, Kumar told reporters in New Delhi.

In October, a group of European Parliament members had visited the region, which is claimed by both India and Pakistan.

The delegation that visited Kashmir on Thursday included US ambassador to India Kenneth Juster and diplomats from Bangladesh, Vietnam, Norway, the Maldives, South Korea, Morocco, Niger, Nigeria, Argentina, the Philippines, Fiji, Uzbekistan, Peru and Togo.

Offices, shops and businesses were open in Srinagar on the cold winter day, but the diplomats did not stop to talk to people as they moved to different venues of their meetings.

They were to fly to Jammu, the winter capital of Kashmir, later Thursday and return to New Delhi on Friday.

Congress leader Jairam Ramesh pointed out the oddity of taking foreign diplomats to the troubled state but not allowing allowing Indian political leaders to freely visit it.

The National Conference said it was "disappointed" with the way the government brought envoys from various countries to "endorse" its "claims of normalcy" in the union territory. The party alleged that it was no more than a "guided tour" with access limited to "handpicked individuals who toe the government line".

“The NC wishes to ask these envoys that if the situation in Jammu & Kashmir is "normal", then why are scores of people, including three former chief ministers, under detention for almost 160 days and why have the people been denied access to the internet for over 5 months?" a statement issued by the party said.

Kumar dismissed as unfounded criticism of the visit, and said more such visits to Kashmir by New Delhi-based diplomats are likely in the near future.

Washington DC, Jun 8: Astronomers acting on a hunch have likely resolved a mystery about young, still-forming stars and regions rich in organic molecules closely surrounding some of them.

They used the National Science Foundation's Karl G Jansky Very Large Array (VLA) to reveal one such region that previously had eluded detection and that revelation answered a longstanding question.

The regions around the young protostars contain complex organic molecules which can further combine into prebiotic molecules that are the first steps on the road to life.

The regions, dubbed "hot corinos" by astronomers, are typically about the size of our solar system and are much warmer than their surroundings, though still quite cold by terrestrial standards.

The first hot corino was discovered in 2003 and only about a dozen have been found so far. Most of these are in binary systems, with two protostars forming simultaneously.

Astronomers have been puzzled by the fact that, in some of these binary systems, they found evidence for a hot corino around one of the protostars but not the other.

"Since the two stars are forming from the same molecular cloud and at the same time, it seemed strange that one would be surrounded by a dense region of complex organic molecules and the other wouldn't," said Cecilia Ceccarelli, of the Institute for Planetary Sciences and Astrophysics at the University of Grenoble (IPAG) in France.

The complex organic molecules were found by detecting specific radio frequencies, called spectral lines, emitted by the molecules. Those characteristic radio frequencies serve as "fingerprints" to identify the chemicals.

The astronomers noted that all the chemicals found in hot corinos had been found by detecting these "fingerprints" at radio frequencies corresponding to wavelengths of only a few millimetres.

"We know that dust blocks those wavelengths, so we decided to look for evidence of these chemicals at longer wavelengths that can easily pass through dust," said Claire Chandler of the National Radio Astronomy Observatory, and principal investigator on the project.

"It struck us that dust might be what was preventing us from detecting the molecules in one of the twin protostars," added Chandler.

The astronomers used the VLA to observe a pair of protostars called IRAS 4A, in a star-forming region about 1,000 light-years from Earth. They observed the pair at wavelengths of centimetres.

At those wavelengths, they sought radio emissions from methanol, CH3OH (wood alcohol, not for drinking). This was a pair in which one protostar clearly had a hot corino and the other did not, as seen using the much shorter wavelengths.

The result confirmed their hunch. "With the VLA, both protostars showed strong evidence of methanol surrounding them. This means that both protostars have hot corinos. The reason we did not see the one at shorter wavelengths was because of dust," said Marta de Simone, a graduate student at IPAG who led the data analysis for this object.

The astronomers cautioned that while both hot corinos now are known to contain methanol, there still may be some chemical differences between them. That, they said, can be settled by looking for other molecules at wavelengths not obscured by dust.

"This result tells us that using centimetre radio wavelengths is necessary to properly study hot corinos," Claudio Codella of Arcetri Astrophysical Observatory in Florence, Italy, said.

"In the future, planned new telescopes such as the next-generation VLA and SKA, will be very important to understanding these objects," added Codella.
