Youyou card is a very appropriate application example of integrating RFID technology into your life. As long as you are active in Taipei City, you will have a “youyou card” in your purse, because as long as you have one card in your hand, you will be in Taipei City. It can almost unimpededly shuttle between major traffic points. It even incorporates the function of an electronic wallet, allowing users to directly use the EasyCard to spend in convenience stores or chain supermarkets, further expanding its use scale and added value.
In fact, the application of the Yoyo card is not only that, in addition to being a contactless smart card, it also has the function of RFID, so as long as it is an application type that uses RFID for data exchange or authentication, you can basically use the Yoyo card. Finish. Therefore, many companies cooperate with the Yoyo card company to transplant the modules of the Yoyo card into other daily necessities, such as watches, mobile phones, etc., to make the appearance of the Yoyo card have different changes. There are even many users who take out the modules in the leisure card by themselves and process them into other personal items for use.
Other applications of EasyCard
At this stage, the most common application scope of the leisure card is the electronic ticket of public transportation. In fact, it can also be used in other corners of life.
• Access control:
In fact, for the current Taiwan area, in addition to being used as a ticket for public transportation and an electronic money wallet for consumption, the EasyCard can also be used as a pass for an access control system, just like some high-priced restaurants require an electronic magnetic card. Only to be able to lead to a specific floor.
Nowadays, new high-tech houses have actually introduced a similar mechanism. Shared gates and elevators also need to be opened through RFID induction, or allow users to go to specific floors. Therefore, as long as the manufacturer is asked to read the original RFID Add the identification information of your leisure card to the database linked by the fetcher. In addition to the RFID tag provided by the original manufacturer, you can also use the leisure card to enter. For access control, it provides another level of control.

This is why the current application range of RFID is still less personalized, but mainly focuses on logistics, tickets, etc.
Perhaps when UHF or microwave RFID technology is more mature and has unified specifications, more personalized applications can be seen (because the amount of data that can be transmitted is larger, and the encryption mechanism is relatively complete), perhaps One day we will really be able to achieve the ultimate goal of “one card in hand, unimpeded”.
