There is a wide range of reader technologies which can be used to identify a user
- Proximity Readers can read cards, key ring tokens, and even specially adapted watches. They work by reading the card or token at a range of between 8cm to 3 metres, so are quick and easy to use. Proximity Cards can also double as an ID card by using printable versions.
- Token Readers read a key ring style token and requires the token to be touched onto the reader. Tokens are also quick and easy to use.
- Swipe Card readers read a magnetic strip on the back of a card. They require the card to be swiped through a slot in the reader. Swipe Cards can also double as an ID card by using printable versions.
The above technologies require the user to carry a token or card. The following options below do not require a token or card to be carried.
- Keypads can be used to grant access via either a unique pin for each user or a generic pin for all users. They are less secure than other methods however provide a convenient method of low security access.
- Finger Print Readers can be used to identify a user and grant access if the fingerprint is authorised. This provides a very convenient and secure method of entry and is the most popular biometric solution.
