Enabling Smartphone Use with Laser Bar Code Readers

Providing a Better User Experience and OEM Hardware Differentiation

Every day, smartphone use continues to increase, and they become more a part of our daily lives. Point-of-sale (POS) retailers have reacted to this by transitioning coupons, loyalty cards, event tickets and gift cards from their usual paper and plastic format to a lower cost, more convenient electronic format.

However, one hurdle to mass implementation of all-electronic barcodes is that laser-based barcode scanners (unlike LED-based) cannot read barcodes shown on smartphone displays.

bar code reflection

Smartphone screens display data using light. The light sensor in a laser barcode scanner is searching for a reflection from the laser, and translates that reflection into barcode data. However, the light source of the phone (the display) doesn’t allow a reflection; all the barcode reader "sees" is a constant reflection, not what is on the display. In plain English, it’s a little like shining a second light source on a shadow; the second light source makes the shadow disappear.

Through the implementation of Mobeam’s® patented Light Based Communication (LBC) technology on PolarPro® 3/3E or ArcticLink® 3 S2/S1 CSSP programmable devices, QuickLogic has solved this issue. LBC technology uses the any LED light source (typically the Infrared LED) present on smartphone to “beam” the barcode data to the laser scanner’s receiver, allowing the coupon code to be read into the retailers system.

Smartphone OEMs implement a programmable logic device from QuickLogic, featuring the LBC technology, during the design stage of a new product. The device can be customized for individual OEMs needs, and can have additional technologies added without increasing product footprint to maximize usage of board space.
