The start up company 'My QRV' is hoping that the custom product created for, and given to, Eva Longoria at the web summit, will earn them a tweet or an Instagram post from the actress.
Founder Victoria Benhaim designed a custom, gold piece for the actress.
"I designed a special one for her - 100% gold with... diamond".
"I gave it to her... and she loved it".
"I hope she will tweet me a picture of her wearing it".
Benhaim came up with the idea for a QRV bracelet - a piece of jewellery featuring an engraved QR code - as her sister is allergic to penicillin.
The QR code sents anyone who scans it to a medical history of the wearer, allowing for quick and easy access by paramedics to records of patients in times of emergency.
The QRV bracelet is designed to look like a piece of jewellery, enabling the wearer to keep the code on at all times. Benhaim designed it so her "fussy" sister would wear it.
"I made one for my sister... I hoped that she would wear it, and she does".
