What is PMU, and how does it work?

Our products are characterized by a unique QR code or RFID, fully integrated into the design of our collection. A third party spots this QR code or RFID and can scan it. On his/her mobile devise a hyperlink to PeekMeUp’s chat system on Facebook and twitter appears. He/she posts their comment about, for example, the bag or T-shirt the QR code or RFID holder is carrying or wearing. The QR code or RFID holder, of course, realizes who is scanning their code. The visual contact, in real time, is the key element of this system. The QR code or RFID holder receives notification that someone has posted a comment on their page. The QR code or RFID owner can then decide whether to reply to this comment. For someone who has previously scanned a QR code or RFID and posted a comment, they receive notification of this on their mobile and can consequently starting chatting. If The QR code or RFID holder has no intention of being in contact with this specific person, they can just ignore his/her post.

Only with the RFID system, the RFID object’s owner can enhance his/her object with any extra information he/she wishes to share. This enhanced implementation offers major advantages:

The RFID owner can add the information he/she wants to share.
Every object becomes unique and, for this reason, the RFID object will be immediately identified, and only the notifications to this specific object will be notified to his/her owner.

This object can be given away, the new owner can decide to leave the previous owners comments or block them and keep only his/her own ones. This last feature is going to be implemented in the short future with no need to substitute by the customer any purchased item.

The RFID tag is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data.
