The Eros card employs the same technology as the Oyster card, an
RFID-based fare payment card used by more than 10 million British commuters in the city's subway and bus system. The
high-frequency (13.56 MHz) passive
inlay inside the Eros card contains a Mifare
chip from
NXP Semiconductors. The card contains a magnetic stripe onto which the customer's account ID number is encoded; that number is also printed on the face of the card.
Unlike the Oyster card, however, the financial transaction is performed remotely with Eros. That is, the amount of money in the Eros account is stored on a server, and the transaction is performed through a payment network, via a message sent from the
reader terminal containing the account ID encoded to the card's RFID chip. In contrast, when a commuter uses an Oyster card, the
interrogator deducts the fare's value from an amount stored on the card.
The Evening Standard worked with several technology vendors to develop the card, Mullins says. TS3 Services Ltd., its lead integration partner, provided the application software that enables online registration and maintains the database card IDs and the value assigned to each card. TS3 Services also installed the RFID-enabled payment terminals—manufactured by
Sagem—at the 15 newspaper vendors accepting the Eros cards, in and around the Waterloo station.
The company worked with
Conchango, a business consultancy in the financial services industry, to develop an interface between the Eros software and the payments network to process transactions when cardholders load value onto their cards. Starting next month, the
Standard plans to roll out the service to more than 30 subways stations and surrounding vendors.
According to Mullins, the
Standard hopes the discounts will entice readers to use the Eros card to purchase the paper with a quick pass of the card over the reader, rather than buying another periodical using a MasterCard or Visa contactless card. Both credit card organizations are rolling out their respective RFID payment cards (PayPass and payWave), which banks in the United Kingdom are beginning to issue (see
MasterCard Rolls Out Contactless Carpet in the U.K.). These cards are heavily marketed to commuters as a method of paying for inexpensive items, such as newspapers or coffee, without having to dig for bills or coins.
