Tokenization
SLIM CD offers a variety of data tokenization methods.
- Tokenization options
- Authentication tokens
- Transaction processing tokens
- Tokens provided by credit card processing companies
Authentication Tokens
Authentication tokens can be public or private. These tokens are used to authenticate the user when performing a transaction, thereby eliminating the dependency on a userid/password mechanism.
Public Authentication Tokens allow software developers to authenticate the transaction from public-facing websites.
Private Authentication Tokens allow developers to post financially significant transactions from server-to-server connections without having to rely on userid/password values.
Authentication tokens are created by logging into SLIMCD.COM. Their use can be restricted by specific transaction types, IP addresses, or browser referral settings. Authentication tokens are unaffected if the merchant changes their password, but can be deactivated by the merchant at any time.
Transient Tokens
Transient Tokens provides a method to queue data for processing. The data is transmitted from the merchant’s website or POS system and queued for immediate processing. When the data is queued, a transient token is returned. This token must be used within minutes, as it expires rapidly. Transient tokens can queue up a variety of data that cannot be stored or tokenized through any other means. This includes card swipe track data and PIN debit pin blocks.
Gateid Tokens
Each SLIM CD transaction that is stored by the SLIM CD servers is represented by a unique transaction id, called a “gateid”. This “gateid” represents the entire transaction on file with SLIM CD, including the cardnumber, expiration date and address of the consumer. The gateid value can be provided to SLIM CD as a tokenized representation for the data on file. This allows developers reuse data in SLIM CD when performing subsequent transactions. Gateid values are returned for each successful credit, check or gift card transaction and can be used to create new transactions. Data can also be loaded into SLIM CD as a way to generate gateid tokens without actually charging the card. Gateid values can be sent to SLIM CD instead of payment data when performing SALE, VOID, CREDIT, and other transaction types.
Processor Tokens
Processing companies are now generating their own tokens that can be used in place of credit card numbers. These tokens are typically merchant-specific. They can be formatted to look like credit card numbers, or can be formatted as other encrypted values. For certain processors, SLIM CD supports returning these values from the processor. For certain processors, SLIM CD also supports accepting these values from the merchant instead of a card number. This functionality can augment Gateid tokens by providing a redundant method for merchants to store tokenized information on transactions without storing the actual card numbers.
