1. The blink card is blue.
   The blink card is round.
2. The blink card can be read by a special machine.

Blink credit cards do everything a regular credit card does. The key difference is that the blink card can be read by a special machine from a few inches away, eliminating the need to hand over your card to a store employee for swiping.

1. privacy
   speedy checkouts
2. both of the above

You can keep your blink card in your hand at all times. Embedded within your blink card is a small RFID (radio frequency identification) microchip that is read quickly by the terminal, which checks with your bank and confirms payment.

1. Speedpass
   Slowpass
2. Roadpass

You can use Speedpass to pay for your gas without ever taking a credit card out of your pocket. Just wave your special keychain fob in front of the Speedpass logo on the gas pump and the cost of the gas will be deducted from your account.

1. the library
   the doctor's office
2. the pharmacy

A JPMorgan Chase & Co. survey found that the top two places people hate to wait is at the doctor's office and at the department of motor vehicles. Blink technology is touted as an important innovation that will save you time waiting on lines.

1. Its data is encrypted.
   Its transmission range is short.
2. both of the above

The transmission range of data transmitted by ISO 14443 is about 4 inches (10 cm) and all data transmitted by it is encrypted (in code). It is particularly suited to keeping private data private.

1. an electric
   a magnetic
2. a radio

In 1831, Michael Faraday discovered that a magnetic field can produce an electric current in wires passing through the field. This is known as Faraday's Law of Induction.

1. microcell
   microchip
2. microcomputer

The blink card's microchip gets its power from the voltage generated by induction in the terminal's magnetic field rather than by a battery. This process is known as inductive coupling.

1. a photo ID
   a signature
2. both of the above

Requiring a signature would slow down the blink process and isn't necessary, because of the blink card's built-in security provisions including encryption.

1. positioning the terminals carefully
   using RFID blocking wallets
2. both of the above

If you're worried that you may end up paying for someone else's purchases by simply getting too close to a blink terminal, you've got reason to be concerned. Check to be sure stores have taken proper precautions and store your blink card in a wallet or sleeve lined with metal to protect you from all unwanted blink card activity.

1. 4 inches (10.2 centimeters)
   24 inches (61.0 centimeters)
2. 48 inches (121.9 centimeters)

You should hold your blink card no more than 4 inches from the reader terminal.

1. two
   20
2. 50

Though Chase claims that blink transactions are 20 percent faster than regular credit card transactions, this is probably due to the fact that signatures aren't necessary.

1. People spend more money with blink cards.
   People are happier with blink cards.
2. People are more economical with blink cards.

One motivation for Chase's interest in promoting blink cards might be that research has shown that people spend more with blink cards than with regular credit cards. Banks need people to use their cards for spending.

1. MasterCard
   American Express
2. both of the above

In addition to Chase's blink card, you might want to try MasterCard's PayPass or American Express' Express Pay, two contactless credit cards that have been introduced in certain markets.

1. keychain fobs
   shoes
2. underwear

Without the restrictions of a magnetic strip, you can expect contactless credit "cards" to take many new forms. Look for keychain fobs, toys, coins and more in the future.

1. frequency
   speed
2. rate

A frequency of 13.56 MHz is suited to inductive coupling, is resistant to environmental interference and claims a low absorption rate by human tissue.
