An IC card security system that tracks kids is now being offered by Tokyu Land Corp. Homeowners who purchase a Tokyu Security home security service plan have the option to enable the Tokyu Kids Security system which sends messages to the parents mobile about where the child is. For this Tokyu has partnered with PASMO Co. which issues rechargeable contactless PASMO IC smartcards for rail and bus systems in Japan.

With the child security function enabled, when the child uses the PASMO card to enter a train station, an email is automatically sent to sent to pre-registered addresses of the parents mobile. The email indicates the location and the text says "passed over the entrance".

The Tokyu Security website depicts the child using the IC card at stations, school, and after school at  cram school. The colorful Tokyu Kids Security PASMO card readers are sold at Tokyu retail stores. Some new offices and residential buildings constructed by Tokyu utilize the PASMO security system at the building entrance. The card is used as a key to enter entrance and lobby areas and the owner’s front door.

If a condo owner purchases the optional Kids Security plan, the "passed over the entrance" email is automatically sent to the pre-registered addresses when the child uses the card to enter or exit the building. The Kids Security plan costs JPY 525 per month in addition to the cost of the basic residential security plan. (Tokyu Security)
