This Boho-Chic Alpaca hand knit Smart-Sweater Vest by j-na couture is in denim with black trim and leather fringe. It is seriously high tech. My virtual business card/chip is on the inside right next to the sweet bone button. Thanks to NFC wearable-technology the vest is smartphone readable, and eliminates the need to carry around and give out those antiquated oh-so-forgettable paper business cards. My smart-vest has literally become my platform and spokesperson to the virtual world. My friends and peers can tap into this platform right from their smartphones when it's held up to my vest. HELLO FUTURE. GOODBYE BUSINESS CARDS. All of j-na couture clothing has these chips in them. For more gorgeous handmade pieces visit j-na couture. Wearing this vest all winter that's for sure.
