Q1: KLTAG tag memory which is divided into several zones?
A: Tagmemory (tag memory) divided Reserved (Reserved), EPC (electronic product code), TID (tag identification number) and User (user) four separate memory blocks (Bank).
Reserved Area: Storage KillPassword (inactivated password) and AccessPassword (access password).
EPC Area: Store EPC numbers.
TID District: Storage tag identification number, each TID number should be unique.
User Area: store user-defined data.
There are also various blocks Lock (Lock) status bit is also used in the storage properties of such a unit.
      Q2: KLTAG label, which has several state?
A: Yes, continuous wave (CW) exposure that power (Power-up) after the label can be in Ready (ready), Arbitrate (cutting), Reply (back order), Acknowledged (answer), Open (Open), Secured (protection), Killed (inactivated) seven kinds of states.
1, Ready state on the label is not inactivated power, they began the state, ready to respond to commands.
2, in the Arbitrate state, primarily Query commands such as waiting for a response.
3, in response to Query, enter the Reply state, further response ACK command can be sent back to EPC number.
4, sent back EPC number, enter Acknowledged state, and further can respond Req_RN command.
5, AccessPassword not zero before they can enter the Open state, in which the read and write operations.
6, it may enter Secured known AccessPassword state, to read, write, lock and other operations.
7, go to the Killed state label will remain unchanged and will never generate a modulated signal to activate the RF field, thereby permanently disabled. Inactivated label should be maintained in all environments Killed state, the power to enter inactivated state. Irreversible inactivation of operation.
To make the label into a state generally requires proper sequencing of a combination method command, in turn, can only be when the label of each command in the appropriate state to be effective, the tag response command will go to other states.
      Q3: Which commands are divided into several categories?
A: From the command architecture and scalability perspective, divided into Mandatory (mandatory), Optional (optional), Proprietary (proprietary) and Custom (customized) four categories.
From the use of functional point of view, is divided into labels Select (Select), Inventory (inventory) and Access (Access) command categories.
In addition, orders for future expansion of the length of different coding aside for later use.
      Q4: essential (Mandatory) command is what?
A: Meets G2 protocol tags and readers, and should support the necessary commands are eleven: Select (Select), Query (query), QueryAdjust (adjust query), QueryRep (repeated queries), ACK (EPC reply) , NAK (steering cutting), Req_RN (random number request), Read (R), Write (write), Kill (inactivated), Lock (lock).
      Q5: Optional (Optional) command what?
A: Meets G2 protocol tags and readers, support can not support the optional command has three: Access (Access), BlockWrite (block write), BlockErase (block erase).
      Q6: Proprietary (Proprietary) command is what?
A: proprietary command is generally used for manufacturing purposes, such as labels and other internal testing, labeling manufactured after this command should be permanently disabled.
      Q7: Custom (Custom) What are the command?
A: Yes, the manufacturers themselves and open to the user defined commands, such as the Philips company provides: BlockLock (block lock), ChangeEAS (EAS change state), EASAlarm (EAS alarm) and other commands (EAS electronic anti-theft system is a commodity ElectronicArticleSurveillance abbreviation).
      Q8: Select (Select) class command what?
A: Only one: Select, is a must.
Tag has a variety of attributes, based on standards and policies set by the user, using the Select command to change some attributes and flags on artificial selection, or the delineation of a particular tag group, you can only count on them to identify or access operation, so helps to reduce conflict and duplication identification, accelerate the recognition speed.
      Q9: Inventory (Inventory) class command what?
A: There are five: Query, QueryAdjust, QueryRep, ACK, NAK, are essential.
1, the label receipt of a valid Query command, meet set standards are selected each tag generates a random number (like dice), and a random number is zero for each label, will reverberate (RN16 temporary password sent back - a 16-bit random number), and transferred to the Reply state; meet some conditions the label will change some of the properties and flags, thus exiting the tag group, helps to reduce duplicate identification.
2, the label QueryAdjust receipt of a valid command, but the new labels to generate a random number (like re-roll the dice), the other with Query.
3, the label receipt of a valid QueryRep command, only the label group in the original random number each label minus one, the other with Query.
4, only one of the labels in order to receive a valid ACK command (using the RN16, or handle Handle - a temporary identity label represents the 16-bit random number. This is a security mechanism!), Received, sent back EPC zone content?? EPC protocol most basic functions.
5, the label after receipt of a valid NAK command, except in Ready, Killed by keeping the original state, the other cases are transferred to Arbitrate state.
      Q10: Access (Access) type command what?
A: There are five essential: Req_RN, Read, Write, Kill, Lock, and three optional: Access, BlockWrite, BlockErase.
1, the label receipt of a valid Req_RN (withRN16orHandle) command, sent back handle or a new RN16, depending on the state and different.
2, the label receipt of a valid Read (withHandle) command, sends back an error type code, or required contents of the block and handle.
3, the label receipt of a valid Write (withRN16 & Handle) command, sends back an error type code, or write back to handle success.
4, label receipt of a valid Kill (withKillPassword, RN16 & Handle) command, sends back an error type code, or inactivation success back handle.
5, the label receipt of a valid Lock (withHandle) command, sends back an error type code, or lock the handle back to success.
6, labels receipt of a valid Access (withAccessPassword, RN16 & Handle) command, sent back handle.
7, labels receipt of a valid BlockWrite (withHandle) command, sends back an error type code, or block write back to handle success.
8, the label receipt of a valid BlockErase (withHandle) command, sends back an error type code, or block erase success back handle.
      Q11: The so-called conflict (collisions) how it is, how anti-collision? What mechanisms G2 anti-conflict?
A: When the above mentioned solution Q9, when there is more than zero, a random number sent back to different pins of the RN16, they will appear at the receive antenna of the waveform superposition of different RN16, also known conflicts (collisions) and thus can not correctly decode. There are many anti-collision mechanism superimposed waveform distortion can be avoided, for example, managed to (midnight) to make certain that only one label "speak", followed by a single treatment, will be able to read and write more than one label identifying each of a label.
The three Q-prefix command reflects the G2 anti-collision mechanism: random number label to send back to zero RN16, if there are multiple tags random number is zero, but not correctly decoded, it is strategically retransmission Q word or a combination of the first command, the tag group to be selected, until it can be correctly decoded.
       Q12: tag identification number (TID) should be unique you? How to reach?
A: tag identification number TID (Tagidentifier) ??is a sign of the difference between the labels identity (analogous to the ticket number). From the safety and security point of view, should not be any two identical G2 label, the label should be unique; Q1 answers from the above, we know that the label four memory blocks each use, and some can always be rewritten after the factory Only TID should also be capable of doing, so the label TID should be unique.
Factory G2 chip manufacturers should use the Lock command or other means acting on the TID, making it permanently locked; and the manufacturer or relevant organizations should ensure that the appropriate length for each TID G2 chip is unique in any case there will be no first two same TID, even if a label is Killed G2 status will not be activated before using its TID (still this tab) will not appear on another G2 label.
Such as TID is unique, although the label EPC codes can be copied to another tab up, but also through the label to distinguish between TID and thus get to the root. Such a framework and methodology is simple and feasible, but be careful to ensure uniqueness of the logic chain.
V109 version of the G2 protocol TID provisions required only 32-bit (including 8-bitallocationclassidentifier ,12-bittagmask-designeridentifier ,12-bittagmodelnumber); need for more bits bit, such as SNR (serialnumber serial number), said is "Tagsmaycontain", rather than "should". However, EPC numbers are designed to be used on single items distinguish ,32-bit is probably not enough, should have SNR. G2 protocol amendments or Class2 will consider these and other bars.
      Q13: G2 agreement inactivated (Kill) command effect how? Can re-use has been inactivated label?
A: G2 protocol sets the Kill command, and use 32-bit passwords to control and effectively use the Kill command tag will never generate a modulated signal to activate the RF field, thereby permanently disabled. But the original data may still label, if you want to read them is not entirely impossible, consider improving the Kill command meaning - with erasing the data. Really the case, then people should be completely at ease.
In addition, in a period of time, the cost of using the G2 label or other reasons, will take into account both labels can be recycled reusable condition (such as the user wants to use tabbed revolving trays, boxes, the contents of the corresponding replacement EPC number, User District contents to rewrite; replace or re-mount tags costly, inconvenient; etc.), you need to be permanently locked even if the labels can also be rewritten command, because the impact of different locking state, or only Write BlockWrite, BlockErase order, not necessarily rewrite EPC number, User Content or Password (if the tag's EPC number is locked and thus can not be rewritten, or not locked but forgot the label AccessPassword and not to rewrite EPC number). This gives rise to a demand that requires a straightforward Erase command - in addition to TID District and Lock Status bit (TID label can not be rewritten after the factory), other EPC numbers, Reserved Area, User Content and other areas Lock status bit, even permanently locked, and will all be erased to prepare for rewriting.
By comparison, improved and increased Kill command Erase command functions the same (including should use KillPassword), the only difference is that the former does not produce the Kill command so the modulation signal, so you can return to the unity brought about by the Kill command different parameters RFU value to consider.
      Q14: G2 access (Access) and other commands are optional, if the label or reader does not support optional commands how to do?
A: If you do not support BlockWrite or BlockErase command can fully Write command (write once 16-bit) instead of more than a few times, because the erasure can be considered a write 0, the former block write, block erase block is several times 16-bit, others using similar conditions.
If you do not support Access command, only AccessPassword to 0, before entering the Secured state to use the Lock command. In the Open or Secured state where you can change AccessPassword, and then use the Lock command locks or permanently locked AccessPassword words (pwd-read/write bit is 1, permalock bit is 0 or 1, the reference schedule), the label never not enter Secured state, and also no longer use the Lock command to change the status of any locks.
If support for Access command, it may use the appropriate command to enter all the various states of freedom, in addition to the label is permanently locked or not locked permanently refused to execute certain commands and is Killed outside the state, but also more effective implementation of the various commands.
G2 agreement provides for an Access Order is optional Optional, but in the future if we let Access command or manufacturers become essential for G2 tag and reader support Access command, then it will control and use more flexible and comprehensive.
