!!! Overview
[{$pagename}] is a [Pseudonymous] [Bank Card Number] values that replace the [Primary Account Number|PAN] in the [Payment Network].
 


The [{$pagename}] is the [Bank Card Number], along with possibly some other information, from the [Issuer Bank|Card Issuer] as a result of the [Card-Emulation] process.

[{$pagename}]s are used to reduce the [risks] inherent to the transfer of sensitive payment data such as the [Primary Account Number|PAN]. 

Generation of the tokens is done by the [Token Service Provider] or [TSP].

During the payment process [{$pagename}] is 
* sent from the handset to the POS device 
* then to the [Card Issuer] for [transaction] authorization
* the [Token Service Provider] also provides a service to map back the [PAN] from the [{$pagename}] used in the transaction, which is sent over the [Payment Network].

This way, the unsecure token space and secure PAN space are distinct areas.

The [{$pagename}] Framework is published in 2014 by [EMVCo Tokenization].

A [{$pagename}] number does not reveal to the Merchant the [PAN] and possibly other information about the purchaser.

The [Payment Token] is a surrogate [Bank Card Number] for a [PAN] that is a valid 13 to 19-digit numeric value that must pass [Luhn Check Digit|Wikipedia:Luhn_algorithm |target='_blank'] and other [CVM] of an account number. 

The Payment Tokens must not have the same value as or conflict with a real [PAN].

[{$pagename}] [MAY] be:
* Limited in [Time To Live]
* Limited by number of uses.
* Capped by maximum amount.
* or other conditions

Both [Apple Pay] and [Google Wallet] utilize a [{$pagename}] in their wallet process, however, they are handled differently.
[{$pagename}] maybe referred to as:
* [EMVCo Token|EMVCo Tokenization]
* Device Account Number (DAN)
* Google Pay Virtual Card
* or various other [Marketing] terms
