In recent years, this type of tag has become a trend. In fact, it's not unusual to see all types of them - for businesses as diverse as grocery stores, pet shops and fitness centers - hanging from thousands of key rings.
The key-chain tags are similar to more traditional plastic cards in that they all carry bar codes. However, a key ring is more easily accessible than a card, which is usually stored in a wallet.
They're extremely popular because of their ease of use for customers. You need your keys to start your car or to get into your home. Most of the time, you have them with you and can grab them quickly.
The tags also provide a wonderful form of advertising. The tags are just another innovation derived from the creation of bar codes and scanners a quarter-century ago and are being utilized by thousands of companies worldwide.
In many cases, retailers are using key tags to offer discounts and special promotions that can be tailored to a particular customer's tastes. At the same time, the stores get an immediate record of who is buying what product and when.
