Stein Mart conducted a referral campaign using direct mail and social sharing to increase store redemptions and build their customer database. They sent 20,000 postcards to existing customers containing a URL linking to an ePush landing page. This page allowed customers to share a $10 off $25 offer through social networks. Over 3,500 people shared the offer, bringing in over 25,000 additional responses and adding over 13,000 new customer names and emails to Stein Mart's database. The social sharing increased store redemptions to 8,000, over 13 times more than the 600 expected.

Optical and afm studies of vacuum evaporated cds thin filmsIAEME Publication
The document summarizes research on the optical and atomic force microscopy (AFM) studies of cadmium sulfide (CdS) thin films prepared by vacuum evaporation. CdS thin films of varying thicknesses were deposited on glass substrates. The optical band gap, absorption coefficient, and extinction coefficient were estimated from optical measurements. AFM images showed the surface morphology consists of round nano particles with grain sizes ranging from 40-180 nm. Both the optical band gap and particle size increased with increasing film thickness, while the extinction coefficient decreased with thickness.

Consisting of an RFID chip for data storage
an antenna to facilitate communication with the RFID chip
A reader/antenna system to interrogate the RFID inlay
Application software and a host computer system
5. RFID TAG
The RFID tag consists of an integrated circuit (IC) embedded in a thin film

antenna circuit embedded in the RFID inlay via radio frequencies, to an
RFID reader

RFID tags data can be changed or added
More effective, bring lots of convenience to us
Negative
Cost is relatively remain high (compare to barcode)
RFID signals may have problems with some materials
RFID standards are still being developed
