1b. What is the price of EPC Class 1 compliance UHF tags?

The prices ranging from 50 cents to 1 dollar.

The fact about RFID:

RFID will not take off until the tags cost less than five cents? Answer is wrong

For many projects you do not need a $0.05 tag to be able to justify the project. The cost of RFID tags has been high. Many vendors are still charging in the $0.50 range. The cost of a tag is defined by many things: cost of silicon, silicon processing, die handling and attachment process, antenna design, form factor of tag. Each of these processes has to be optimized to get the lowest cost tag price. Many companies are working to do this, not just for EPCglobal™ tags but for all RFID tags. The final factor in all this is volume. If there is a large enough order, the price will fall as economies of scale come in to play. This is true for all frequencies of RFID tags. Of course some tags will always be more expensive than others, the cost of a wire antenna is likely to always be more than that of a printed one. The five cent tag is still in the future when manufacturing techniques have been devised to help reduce the cost, but many applications can show a good ROI on tags at the $1.00 - $0.50 level.

What is EPC?

EPC stands for Electronic Product Code. Like a bar code, the EPC is divided into numbers that identify the manufacturer, product, version, and serial number. The EPC however, uses an extra set of digits to identify unique items. The EPC is the only information stored on an RFID tag's integrated circuit and it enables an infinite amount of dynamic data that can be associated with an item.

What is EPC compliance?

EPC compliance refers to adhering to the specifications set by EPCglobal (formerly AUTO ID, Inc.) for RFID. In order to realize the EPC vision of an "internet of things", RFID systems must be available from a variety of vendors and must work together and be interoperable.

What are the EPC Standards?

The Auto ID Center (now administered by EPCglobal) has developed a Class 1 standard for UHF systems to act as the foundation for EPC hardware. The standard is necessary to address user requirements: low cost hardware, writable tags, solid range and speed, global application, and open to many hardware vendors. Class 1 tags are expected to be the most widely deployed of all, as they are the backbone of the EPC system. The Center started with Class 1 as the foundation for its standard-setting efforts because it is crucial to make the Class 1 system as simple and low-cost as possible, while still leaving a forward path to interoperable higher-functionality systems.

How will the standards be enforced?

EPCglobal will assume responsibility for implementing the specifications as standards and certify EPC systems as compliant.

From how far away can a tag be read?

EPC Class 1 UHF tags can be read at 1 meter (~3 ft) in any orientation, and up to 5 meters (~15 ft) if held in the optimum orientation. Battery-powered tags can be read reliably at up to 30 meters (~100 ft).
