|
| Random Access Memory |
A volatile memory used in integrated circuit cards that requires
power to maintain data. |
|
| Read on Insertion |
Reading information from a magnetic stripe while the card is
being inserted into the reader device |
|
| Read on Withdrawal |
Reading information from a magnetic stripe while the card is
being removed from the reader device. |
|
| Read-Only Memory |
Non-volatile memory that is written once, usually during card
production. It is used to store operating systems and algorithms
employed by the microprocessor in an integrated circuit card during
transactions. |
|
| Reflex Hologram |
A hologram produced in film form similar to a photonegative
that gives full 3-D imagery. |
|
| Reg “E” Registration Authority |
Regulation promulgated by the US Federal Reserve Bank under
the Electronic Funds Transfer Act establishing the right and responsibilities
of parties involved in electronic funds transfer transactions.
|
|
| Registration Authority |
A party usually designated by a standards body to register identifiers
or codes. |
|
| Relief Height |
The height above the surface of the card of characters formed
on it by embossing. For ISO standard identification cards this
height should not exceed 0.48mm (defined in ISO 7811) |
|
| Reloadable Prepayment Card |
A prepayment card where the cardholder can add value after the
initial issuance of the card. |
|
| Remote Batch Terminal |
A terminal remote from the computer to which it is connected
which collects data for and returns data from batch processing.
|
|
| Repudiation |
Denial by a party to a transaction that the transaction ever
took place. |
|
| Retailer Card |
Proprietary card issued by a retailer or retailing group |
|
| Retinal Scan |
A Personal Identification Verification technique based on an
infrared scan of the eye retina. |
|
| Retinal-Scanning |
A device used to recognize patterns in a human retina. The
device makes a digitized image of a strip of retina. This image
can then be compared with a pre-stored one. Retinal patterns are
almost unique to individuals and retinal scanning is currently
on of the most powerful methods of biometric authentication. |
|
| Routing |
The chain of transmissions by which a transaction passes from
an acquirer to a card issuer in a payment system. |
|
| RSA Algorithm |
AN asymmetric (public key) algorithm developed by Rivest, Shamir,
and Adleman |
|
| RSA - Rivest Shamir - Adleman Cryptosystem |
A public key cryptosystem in which public and secret keys are
derived from the factors of very large numbers. |
|
| Runaway Card |
A lost or stolen card that is being misused frequently and fast.
