Thick wallet turned into a bag, Sinji Pouch Basic 4

Sinji Pouch is a product that won the 2011 D2B Design Fair Award. It is a card pouch used as an attachment at the back of the smartphone. As smartphones are always carried around, attaching a pouch makes it convenient and safe. There’s no need to open a bag or wallet to get your transportation card. Moreover, smart consumption is made possible by accommodating various point cards.

How to use


1.  When using my transportation card or ID card inside the Sinji Pouch, it sometimes is not recognized. Why is that so?  

The transportation card or ID card often transmits or receives wireless transmissions, while electromagnetic waves from the smartphone, or the metallic material on its surface, disrupt wireless recognition. Particularly, the aluminum used for the body of the iPhone 5 / 5s and iPhone 6 / 6 plus disturbs the electric waves and causes a significant drop in recognition rate.

In this case, inserting a material that can absorb the electromagnetic waves between the transportation card and the smartphone can increase the recognition rate. The electromagnetic wave absorbing card of Sinjimoru has the function to absorb electromagnetic waves and transform them into thermal energy. Thus, it can be used to increase the recognition rate. Moreover, if a different kind of card is inserted between the transportation card and the smartphone, the electromagnetic waves are partially absorbed and thus it helps to improve the recognition rate.

2. What is the maximum number of cards for the pouch?

We usually recommend inserting 3, but it may store up to a maximum of 10.

3. Is there a concern of cards falling out due to stretched fabric? 

The fabric used for Sinji Pouch is a highly elastic fiber that easily recovers from every day use. Thus, there is no need to worry about cards easily falling out.

4. Can it still be used after removal?

We do not recommend reusing the Sinji Pouch since its adhesive tape does not support it. However, as adhesive power remains to a certain level even after removal, it may be reused if there are no alien substances.

5. What are the differences among the Sinji Pouch series and with which criteria should I select them?
