Cool ring! At work it is convenient to open the doors now) size, only, slightly more than expected. 2 keys are read by MIFARE readers (13,56 MHz), their UID is not rewritable. And one read by EM-Marine readers (125 kHz). Here is his UID can be overwritten. It is necessary to arrange with interphones somehow to make MIFARE the key to the base of the entrance. Many opportunities open when working with a smartphone with NFC module. But, for me, it's clear to play and forget. Although, there are interesting pluski, for example, the record in the ring of different information. In general, stylish, fashionable, youth, modern)) every fan of gadgets should try it)

What can I say about the ring:
1. could only write to ID the entry key of the Vizit system. Registered immediately. Registered in the workshop for making keys for 500 tenge in Pavlodar Kazakhstan.
2. binding map Caspian gold Caspian bank could not independently to ring for non-contact payments. I was told to the bank that the bank does not do such procedures with cards. On the fifth day of using the ring one of 3 stones peeled off and lost. Due to, that the ring does not correspond to the description and does not perform all the declared functions I opened a dispute about the return of 10 $. The seller agreed with my dispute. For which the seller Thank you.
