Octopus is widely used in Hong Kong for purchases on public transport, and in convenience stores, fast food shops, supermarkets, cake shops, vending machines, schools and parking. Octopus is also used for office and residential premises access control.

Each Octopus has a built-in microchip containing an electronic purse and other applications which can accurately record the holders' transaction details. Users simply wave their Octopus over a reader, and the correct amount will be deducted automatically. There's no longer a need for coins.

Using Your Octopus

	Use of an Octopus is subject to the Conditions of Issue of Octopus
	If the value of your Octopus is positive (i.e. HK$0.1 or above) but insufficient to cover the full cost of your next transaction, you may incur a negative value of up to HK$35, which will be recovered when your card is reloaded.
	If the value on your Octopus is zero or negative, your Octopus cannot be used until it is reloaded.
	Special offers for Octopus holders, such as concessionary fares for children or the elderly, are subject to the terms and conditions issued by the relevant transportation companies or organisations.
	The card will be valid for 3 years from the last add value date.
