A selective transaction authorisation method and system

A selective transaction authorisation method including the steps of receiving a payment authorisation request for a transaction, said request including restriction information indicating a restricted purchase is requested; determining a status of an account being used to make the transaction; and declining the payment authorisation request if the status of the account does not meet a requirement of the restricted purchase, or authorising the payment authorisation request if the status of the account does meet the requirement of the restricted purchase. The restriction information may include age verification information, wherein authorisation may be declined if the account is not eligible to purchase age restricted items; or discount information, wherein authorisation may be declined if the account does not qualify for the discount. The restriction information may be generated by a point-of-sale system. If the authorisation request is declined an alert may generated and sent to a third party who may authorise a subsequent payment authorisation request. The payment authorisation request may also include restriction categorisation information and may further include a merchant identifier such that the authorisation request may be declined if the merchant is not included in a list of approved merchants.
