Key Cards


Hotel keys have gone the way of rotary telephones, luggage stickers and luggage trunks—vintage collectibles. Taking their place are magnetic key cards, which let visitors gain entry into hotel rooms. Key cards have become commonplace in the lodging industry. Many other businesses and industries use security key cards to limit access to company buildings or to certain areas within company buildings. Key cards provide several benefits over traditional keys including:
  1. Cost effectiveness: Key card systems eliminate the need for re-keying locks when a guest or an employee has taken off with or lost a key.
  2. Security: In the hotel industry, security key cards are not marked with room numbers.
  3. Limiting Access: Security key cards can be used by companies that want to prevent non-employees from entering the premises or that want to restrict admittance to specific areas.
  4. Marketing opportunities: Advertising key cards enable you to print information on your key cards to promote your brand or advertise services.

Hotel key cards

Hotel key cards have a magnetic strip on the back that is programmed each time a guest checks in. Magnetic key cards work only on the guest's room lock and only for the duration of their stay.

Key card systems go green

Some manufacturers are offering key cards made using green manufacturing practices or key cards made from recycled or biodegradable materials.

Special event key cards

Hotels often partner with special events and conventions to offer custom printed key cards that commemorate the event. Sporting events and conventions can also use custom printed magnetic key cards in place of paper tickets.

Advertising key cards

Restaurants and businesses can partner with nearby hotels to offer co-op advertising on key cards.

Locks that work with key cards

Before you invest in key cards, figure out which key card locks to purchase. Most key card locks come with their own controllers, programmers and software that enable you to program the magnetic key cards.

Security key cards keep your business secure

Key card systems limit access to your establishment and eliminate the need to change the locks if an employee loses a key, resigns or is terminated. Security key cards come in magnetic stripe or proximity varieties. Magnetic stripe key cards are swiped through a card reader. Proximity key cards are waved in front of a key card reader.
